Pegasus in the Shop: Sort of?

In 1963, a New Jersey teenager, Bill Schill, won the Moth Worlds at Larchmont YC sailing a Fletcher-Cates design named Pegasus. The following two photos are of Bill and Pegasus during the glory years.

After Bill died, George A. over at the Mid-Atlantic Musings blog inherited a very dilpidated Pegasus which further malingered in his back yard for a few years. This winter, Bill Boyle, with the help of George, decided to take on the restoration of this piece of U.S.A. Mothboat history - a major, major undertaking after Pegasus oozed out of the back of Bill's truck. Ouch!

Once Pegasus was ensconced in Bill's shop, it was discovered there wasn't much worth saving. Bill's woeful analysis:

"So, here we are. This is what's left. We have a keel, a DB case and the stem. Well, most of the stem. George and I spent about two hours removing the rest of the bow section. We were hoping to get the panels off intact but that didn't happen. We're starting from scratch."

So there it is, a new build with a couple of old parts. Click over here to see Bill Boyle's restoration blog for Pegasus.

Bill Schill, in his senior years, was up for some weird Mothboat projects. He rescued a Duflos hull that had been cut in half, and then hung as decoration in a bar for thirty years. Undeterred, he glommed another side onto her. Here he is in 2009 in this half-in-half project that he got back on the water.

Header Photo: Classic Moth E-City Nationals 2016

Darin McCauley

The previous header photo was taken by professional photographer, Darin McCauley, at this year's Classic Moth Nationals at Elizabeth City. If you look closely, you can see this photo was captured just a millisecond after the point of no return, witnessed by the still present trail of water coming off the tip of the daggerboard. (Also many thanks to Jay Yerkes for performing this difficult athletic maneuver so elegantly.)

I didn't make this year's Nationals because, for most of the summer, my head wasn't into racing. Turnout was off this year for the Nationals but the local fleets in Maryland and South Carolina are gaining strength with local regattas featuring 11 Classic Moths - so a bit of a trade-off.

I feature several other of Darin's excellent photos below. Just a quick plug for Darin, he writes;

"If you know of anyone who could use photographic coverage of any sailing event please let them know I'm available!"

Gary Gowan won the Gen I division in his home-built, woodie, modified Cates (he actually finished third overall which I think is a first for a Gen I since we started slotting the slower designs into their own division).

For the first time in a while, there were no vintage Classic Moths racing in 2016. It is also interesting that 9 out of the 12 competing were wooden dinghies.

2015 Classic Moth Nationals

The 2015 Classic Moth Nationals at E-City this past weekend had two glorious sunny days with winds mostly under ten knots. Jamey Rabbit repeated as National Champ with an even more dominating performance than he had last year. As usual, the Gen II Mistral or modified Mistral designs filled the top four positions. Rod Mincher returned to the Nationals after a several year layoff to take the Gen I division in his Maser. Gary Gowans, who won Gen I last year, copped another victory this year, in the Vintage division.

The fleet was split almost evenly among the divisions with 6 Gen II, 5 Gen I, and 6 Vintage to make a total of 17 Classic Moths.

I was able to wander around and take some yard shots of a few of the Classic Moth fraternity/sorority.

Usually the Classic Moth Greybeard Society doesn't have a quorum at the Nationals but this year they did. Dan Mallott, Gary Gowans, and Jahn.

Bill Boyle, who was the lead builder on the Tweezer project, has built or restored a bunch of Classic Moths. Here he is with his restored Ventnor.

Joe Courter, who puts on the great pre-race party at the Brigantine Regatta, got the Old Goat award (he's well into his 70's).

National Champion for the second year in a row, Jamey Rabbit,

John Zsecleczky finished third overall.

Mike Parsons finished second overall.

Tweezer...........Gone!

Classic Moth design, Le dessein Moth Classique



I've retired Tweezer, my beautiful Gen2 Classic Moth. She's gone back to Bill Boyle, one of her original build team. It's tough to let go of a boat you designed, built and then raced since 2004...... but it's time.

I designed Tweezer with flatter rocker and a potential higher speed without realizing that most Classic Moth racing on the East Coast is shorter course, with lighter air, large shifts and variations in wind speed. Tweezer did fine in a breeze, winning a regatta now and then but always struggled when the wind was down. Part of it was wetted surface, part of it was some of the extra volume up front that seemed to plow when going offwind. Tweezer was also slightly heavy which I could have attacked by redecking her, but she was too beautiful for that.

Tweezer hull lines;

And my!...my!...my!... was she a beautiful little sailing craft. Strip planked out of Atlantic Cedar, both hull and side decks. I'm not known as Mr. Maintenance, but with Tweezer I kept the varnish up. Every time I went on a road trip, I would get someone wandering over at a gas station, rest stop, supermarket to admire and talk boats. They may have just finished some wood kayaks, own some oddball catamaran, or crew on a tall ship, but Tweezer attracted boat nuts of all persuasions to come over and chat.

I'm proud of the design. Tweezer was remarkably vice free, would tack like a dream and kept the bow up reasonably well when going downwind in breeze and waves. As a narrow waterline design she had her quirks and could dump you for inattention, but thats what a Gen 2 Classic Moth is all about.

No regrets at all about the Tweezer project. All great memories in the designing building and sailing of the Tweezer. Again, I would like to offer up my thanks to Bill Boyle and George Albaugh who ensured that Tweezer got built.

Andy Slavinskas did some beautiful 3D CAD rendering of the Tweezer lines. His perspectives are shown below.

Here is the YouTube video of her build;

(editors note - I've dragged the Conclusion to the top of the post - August 2013) CONCLUSION - Let me be clear. The Classic Moth is a short hull and a light hull. At the Gen2 (higher performance racing) level, the Classic Moths are challenging craft to sail but very rewarding at the same time.  A Laser is like an aircraft carrier compared to the more twitchier Gen 2 designs, the Mistral, Energizer, Tweezer or even the Shelly. 

But there are more stable Classic Moths that we classify as Gen 1. I've never sailed a Mint or a Proust design but I would assume that they would be very much the same stability as a Laser or Sunfish. Or, an even older design, a reproduction vintage design such as the Little Mae or Nantais Moth would be the most stable and perfect for kicking around on the lake. 

So there you have it. The Mistral, Shelly and Florida Cates have more or less complete plans. Other designs you would probably need to work off a set of lines drawings and use your builders experience. George Albaugh is our plan librarian. His email is linked from Classic Moth website.  George is also another sailing blogger. You can view his Classic Moth posts over at Mid-Atlantic Musings.

All lines drawings (except the Europe dinghy) were done using MaxSurf's NURBS software.

Quick review of some of the more popular designs and the availability of plans. (Updated September 2012)

(Note; To give a rough idea on the tippiness of a hull, Joe Bousquet developed a scissor-like device he placed over the midsection to visually show the amount of V. I've included his pictures of the various V's from the Mistral, Shelly, Europe, Energizer.)

(Another note: To scroll through hi-res pictures, just click on a picture. Once the hi-res picture comes up, click again in the picture to step through all the pictures on this post.)

MISTRAL - easiest to build. Developable plywood. Stitch and glue. Two 3mm plywood panels are bent up to shape, a centerline piece attached to hold the run flat, a spreader bar at the gunwhales is used to get the correct shape when bending up and glassing. A weekend of work will give you the rough shape. Adding two permanent bulkheads, a temp bulkhead and the transom finalizes the shape. Many people have hacked the hull shape by pushing here or pulling there so we have some semi Mistral hullls out there. Here is a link to a blog post of a local Annapolis Mothist, John Z building a Mistral. A Mistral or some variation of the Mistral has won the Nationals the last umpteen years.

However, the Mistral is a very deep V design. Very floppy and has a tendency to scare newbie Mothists who try to sail her. Many have come ashore and either; 1) rapidly put the boat up for sale or 2) put the Mistral back in the garage for a while and then discreetly sold her. Not all mind you, as we have a core group of about 6-8 who regularly sail a Mistral (or modified Mistral design, i.e. the Mousetrap or Y2K designs) and are able to race them hard in all conditions and win. It helps to have some Laser or Sunfish experience but this is not an ironclad requirement. If you pick a Mistral to build, consider yourself warned. If you decide to proceed, George has the plans (see bottom of article).

Not all Mistrals are built in plywood. This one was done in foam core/glass, with the hull splashed using an existing wood hull as a mold. Note the very interesting transom design.

Here are the lines to a modified Mistral, the Y2KBug built by Walt Collins. (Pretty extreme wouldn't you say!)

ENERGIZER -Just a hair more stable than the Mistral is the Energizer design. A modification of the 1970's Stockholm Sprite, it is a full chine design but still very V'd. Two have been built with some success. No plans.

Energizer on the Bousquet V-meter.


The original Energizer was the first Classic Moth I owned. Here I am sailing Energizer at Chester River in Maryland.

TWEEZER - Yep, this is my design. I called this design Tweezer D as it was the fourth generation in what I drew up, but the D version was only one built. A Gen 2 design racing against the Mistral, Energizer designs. Stability somewhere between the Mistral and the Shelly (though some other sailors have told me it is close in stability to a Shelley). Flatter rocker in the Tweezer has proven to be quick in a breeze but suffers against the Mistrals and even the Shelly in the lighter stuff (non-hiking breeze) which, on the East Coast, seems to be the majority of our conditions. I may be biased but it is a hull with little vices and I enjoyed racing this design. Round-bilged and the original was built using cedar strips.

SHELLEY - A wider, flatter chined design with moderate rocker from the brilliant New Zealand/English dinghy designer of the 1960's, John Shelley. Much more stable and, in the hands of Joe Bousquet, has done very well in the National championships. George has the Mk3 plans.

MINT - Qualifies for Gen 1 (our Classic Moth division for the more stable, higher wetted surface hulls that are not Vintage). A Bill Lee national championship winner, the Mint is a reasonably docile design from the 1950's. Never built one but the bow sections go very fine and look to present some challenges to the home builder. That being said, 6 hulls were built in Elizabeth City in the 1990's. George has the section lines.

FLORIDA CATES

The most successful American design of the 1960's. Florida boatbuilder, Harry Cates, evolved the shape from Warren Bailey's Mach 1. massaging the shape to make it easy to home build in plywood. Charlie Hunt drew up the plans. A Gen 1 design, the Cates is another V'd shape with a distinctive small topside panel with chine. The transom is small, reminding one of a Sunfish transom. The Cates is very beamy at the gunwhales forward. Low freeboard, a wet boat, but most sailors find it reasonably sailable, with plans available. George A. has the plans (see contact info at top of post).

Gary Gowans has built two of them, with slight modifications. He won the Gen1 class at the 2014 Championships over an Olympic Europe.

A topside shot of a Cates. Bill Boyle in 1965.

The lines to the Cates show a considerable V, hollowed bow sections, and a tiny topside panel. Beam is 1.72 meters.

The top down view shows a pinched transom and wide side-decks.

The sideview shows moderate rocker. The tiny topside panel that disappears at the bow is also clearly shown.

The offsets to the Cates design can be found by clicking here.

MODERN FLORIDA -There are two designs by famous Florida MORC designers; OH Rodgers designed the Florida Wedge (a low rocker design, very stable, but slow in waves and squirrely downwind in a breeze). Four hulls were built by the St. Petersburg fleet and Jeff Linton won the 2003 Nationals with one. I'm not sure if any plans exist.

A stern view of the Florida Wedge showing the flattish, low profile, transom and no stern tank:

Paul Lindenberg designed a Classic Moth which has a resemblance to the Windmill hull. Lindenberg will sell his Classic Moth plans for $400. I don't have an address.

Lindenberg's website does show some Classic Moth building.

A transom photo of a Lindenberg Moth (from George A.'s blog). Note the anti-reflective strips on the transom for safer trailering.

SAVANNAH WEDGE - A Moth copy of the Zuma dinghy built by AMF in the late 1980's, this Classic Moth was designed by Lane Reeves with two built in Savannah, Georgia.  This Wedge design had a wide, flat transom, low freeboard, double-bottom and reverse stern. The Savannah Wedge is not competitive as a Classic Moth racer, too much wetted surface, but with it's double bottom this is a very capable kick-around-the-lake daysailor. No plans existing that I know of.

Briggs Monteith begs to differ with my assessment - I have dragged his comment to the main post:

"I know this is an old post but as for the Savannah Wedge not being competitive, I finished third in a Savannah Wedge in the '99 midwinters sailing one that I borrowed from Jerry Carter. The boat was amazingly quick I thought, It beat Mean Tangerine and Randall Swans Vanilla. in extremely light air conditions. I think the boat has suffered from sailors who didn't understand the boat." -Briggs Monteith

SKOL; The Skol was a British production fiberglass Moth from the early 1970's. The Mk II, the most popular version, was a de-tuned Mistral with very round sections.  The Mk II had a tub cockpit with a back tank. Here are two pictures of a just retrieved, hence dirty, Skol Mk II. The winglets are illegal in the U.S. Classic Moth Association Rules. (We have a 1" hollow rule.). There are no known plans but a used one would make a good re-decking project (see the last photo is this section).

The original ad for the Skol Mk II

Here in the U.S. Joe Bousquet did a decks-off/plywood redeck restoration of a Skol Mk II, shown here sailing in the 2014 CMBA Midwinters.

A transom shot of the same Americanized Skol. A very round transom, equivalent to the Duflos or Mistral shape.

EUROPE Dinghy- The ex-Olympic Europe is based on a 1960's Europa Classic Moth and there is an active section of Classic Mothists who have purchased plastic Europes, modified the sail to fit the Classic Moth and are sailing them mostly as stock (though we do have three modified Europes, Mark Saunders has done a Europe hull lighter with a wooden deck).

PROUST DESIGN - In 2009, Jim Young built an old French design he found on the Internet. Despite the name he gave her (Tippy), this Classic Moth was anything but. A stable, buoyant design which Jim built modern, in foam/glass. Details on "Tippy" can be found over at this blog post. I've also put up offsets, both metric and English, for my version of the Proust, the Zippy.Also the Zippy sections are posted here.


Tippy at the 2008 E-City Nationals.

The simple single-chine sections for Zippy. There is no compounding of plywood here. This design has ample flotation forward, which makes for a safer hull, particularly downwind in a blow. (For reference, buttock lines spaced at 150mm and waterlines spaced at 60mm.)

---

TITAN - The Titan design is another stable design from the 1960's. It is a round-bilged design, a pretty hull, but the original hulls were built very heavy in fiberglass. Reports from Mothists who have sailed them find the Titan well mannered. The design has some similarity to a small Uffa Fox International 14.

---

RESTORATION - Many of the 60 designs have reappeared as derelict hulls and have been restored rather than homebuilt from scratch. The oldest designs for Vintage (Ventnor, Connecticut, and Dorr Willey designs) must be restored to qualify to race in  the Vintage division (you can still race a reproduction Vintage in the Gen 1 division). 

Here is one of the original ads for the Ventnor Moth.

Bill Boyle has done quite a few Moth restorations and has written about them.

1. Click here to view his restoration of a Fran Abbott Moth.
2. Click here to view his restoration of a Fletcher/Cates Moth.
3. And his latest restoration of a Ventnor copy.

DESIGN YOUR OWN - With the introduction of free hull design software, the more adventurous can design their own Classic Moth. The American rule limits length to 3.3528 meters, beam is limited to 1.524 meters, no concavity greater than .025 meters aft of the daggerboard trunk and hull weight (including fittings) is no lighter than 34 kg.

John Watkins published this set of Classic Moth lines to the WoodenBoat forum in 2015. This design would fit very nicely into the U.S. Gen 1 division.

MARIPOSA

Mariposa is a French Classic Moth three plank design by Bertrand Warion, featuring a flat rocker panel married to developable bow sections, built stitch and tape. The design was one of several new Classic Moth designs built for the "concours de plans Moth Classique" sponsored by the French traditional boating magazine, Chasse-Marée in 2001.

RAZMOTH - another French design by Bertrand Warion. This one is patterned after the Fireball and has a flat rocker panel. RazMoth is another simple flat, two chine, easy-to-build plywood shape, ending in a scow bow. The RazMoth design is on it's second iteration.

BILBON - was another French design built for the "concours de plans Moth Classique" sponsored by Chassse_Marée magazine in 2001. Designed by Christophe Couton, a professional draftsman, it is a simple flat V, easy-to-build plywood shape, ending in a pram bow. Bilbon was one of the faster new designs that appeared at the 2001 design competition.

Here is a middle-of-the-road round bilge design I drew up. A very conventional dinghy hull shape. For reference the waterlines are drawn spaced every 60 mm. and the buttocks are drawn at 150 mm. spacing

Click here for the DXF file of this round bilged Classic Moth design.

I've also pushed around the lines to the Fragniere design by adding a flat rocker panel.

Click here for the offsets for a three plank modified Fragniere Classic Moth design.

William Crosby's SKIMMER - A very early Moth design, published in The Rudder in 1933. According to Crosby, hundreds were built but very few have surfaced in modern times. A scow type, this would make a good off-the-beach boat but is not competitive in the Vintage Divsion when compared to the deeper V vintage designs like the Dorr-Willey or Ventnor.

Skimmer Plans can be found here.

A Skimmer found in a barn in Cape Cod. Note the lack of cockpit.

MASER - And for those with the true hacker spirit - there is the Classic Moth that uses a sliced and diced Laser hull - deemed a Maser.

A Maser at the 2011 Midwinters. You can sort of see the Laser transom, still intact.

MOTH CLASSIQUE: The French have a rich tradition with the Classic Moths and their designs. The French Duflos was the fastest Classic Moth before the arrival of wings. Click here to view Part 1 of Louis Pillon's fascinating history of the French Moth class. I have come across two small jpeg's of French Moth designs on the Internet.

The first is the vintage, scow bow Nantais design which has been mentioned before in this post.

The second is the Fragniere design, a unique transom bow design which was most popular in France before the appearance of the very narrow Duflos and similar designs. Click here for the offsets for the Fragniere.

Here are some photos of a recent build of the Fragniere design. Following the plans, the Fragniere has a full length cockpit.

French designer Francois Vivier has designed a Moth Classique to be built in kit form. Here is the side view of his Moth Grand Largue.

Benoit Duflos, who pioneered the very fast, very Vee'd, very tippy racing Moths of the 1960's also designed a more stable, flat-bottom Moth for the home-builder. Called the Moth-Pop, plans for the Moth-Pop can be found in the links at the top of this post. Here is Benoit's iso-view of the Moth-Pop

The 505 Moth - John Westell, the designer of the 505, also did a 505 type Moth. I haven't come across any that have survived to the modern day.

SCOW Moth - The scow Moth was THE Moth of Australia and New Zealand until the narrow waterline winged Moths proved faster in the mid 1980's. Len Morris was the founder of the Australian scow Moths with his Flutterby design which he built in 1928. His post World War II MK II design was very popular and is still an easy-build proposition out of plywood. Plans for the MK II can be found by clicking here.

The sections for the MK II show a simple flat-bottom scow with vertical sides.

Where to put the mast and daggerboard in a Classic Moth?

Luckily, John Shelley's construction drawings for the Shelley Mk 1, which he used in a patent application, have now surfaced on the internet. His mast and daggerboard placement as indicated in the drawings below are good placements, though, if you went around the fleet with a measuring tape, you would find this might vary by up to 75 mm from boat to boat. 

Center of mast back from stem - 695 mm.

Leading edge of daggerboard back from stem - 1453 mm.

What constitutes a Gen I Classic Moth design?

"What constitutes a Gen I Classic Moth?" As of now, and for the foreseeable future, the good old eyeball. Among the class, we have discussed various parametrics, but the difficulty of measurement, and the almost certain chance of designers trying to skirt any numbers written down (bumps, lumps and so on), have kept us to a subjective division. Most of the designs featured on the this design page are Gen 1 designs. They include the Europe dinghy, the Proust (Tippy or Zippy), the Shelley, the Florida and Savannah Wedge, the Maser, the scows, the Cates, the Mint, the Nantais, the Little Mae, and the Titan. The age of the design does not matter for Gen 1. The primary determinant is waterline beam. If it looks narrow, it doesn't fit Gen 1. Sailing a Gen 1 design should be relatively straightforward for anyone with dinghy experience.

The Gen II designs (narrow waterline) on the Earwigoagin design page are the Mistral, the hard-chine Energizer, the Tweezer, and the wood-decked, modified Skol. They are definitely a tippier proposition to sail and race, but rewarding for those who like a small boat challenge.
