Historical 18-footers on American shores - Photos by Bob Ames

As mentioned in a previous post, three Australian Historical 18-footers were in Annapolis this past week to race against each other as well as the National Sailing Hall of Fame's two sandbaggers.

The 18-footers launched off of Bembe Beach, hosted through the courtesy of the Annapolis Sailing School.

Bob Ames got to be one of the guest crew for one of the race days and sends along these photos he took of the three 18-footers rigging and launching from Bembe Beach.

Header Photo: 49'er Skying

The previous header photo was of the Australian 49'er I plucked from the Internet, hence the location is unknown, but, if I had to guess, I would say this is a screen shot from the famous/infamous medal race at the 2008 Quingdao Olympics.

Australian 12-Foot Cadet Junior Trainer

Nope, I'm not posting about the Jack Holt designed, 3.2 meter, 10.5 foot junior dinghy, popular internationally. This is the Australian 12-foot Cadet, a lapstrake open dinghy, designed in the 1920's and still used as a junior trainer by the Royal Brighton Yacht Club in Melbourne, Australia. The 12-foot Cadet, definitely an anachronism in this modern age, is still used by the RBYC and seems very much at home in the big wind and big water of Port Phillip Bay.

A vintage restored Cadet Dinghy. Sporting a skeg and gently swooping sheer, you couldn't get any more classic lines for an old traditional dinghy, .

Big winds, big waves, spinnaker pulling. The juniors sail them three up and the modern ones are fiberglass with aluminum masts. These dinghies do sport big rigs and a jib that hangs off a bowsprit, both are hallmarks of vintage Australian dinghies.

Clark's UFO; "Peoples" Foiler

Speaking of Steve Clark; he and his son David have been developing an easy-to-use foiler, the UFO, which is now in production from David's shop, Fulcrum Speedworks.

I was able to sneak into the Annapolis Spring Boat Show before it opened back in April and took some quick photos of the UFO. Unfortunately David wasn't around so I didn't have a conversation with him.

The UFO is a short catamaran configuration. One of the main components of a foiler's performance is the ability to keep everything light; cutting down on the surface area of the platform is one way to cut out weight. One must remember that the platform has no contribution to speed and exists to keep all the foiling bits, skipper, and rig tied together (and float everything when not foiling).

I gather the UFO has a low ride height setting for beginners (so that if you lose it the hulls won't come crashing down from up high) and a higher ride for the experts who want to go faster. Photos from the Internet show a weight tolerant package with several skippers over 90 kg (200 lbs) getting the UFO up and going.

I am no foiling expert so it would be best, if you are interested, to scan the Internet for further information.

A link to the UFO class website.

The main foil retracts between the two hulls so the UFO can be rigged upright, launched upright, and beached upright. The foils were designed by a French guru attached to Franck Cammas' foiling group.

There must be quite a bit of fancy composite engineering going on as both the high load main foil and high load mast step are situated back-to-back just at the front end of the forward beam.

Just enough clearance for the main foil to retract between the two hulls. The lime green non-skid gives some contrast to what is basically a white/black package (like most production small boats today).

The rudder and rudder foil sit off a short gantry, again another piece that needs to be engineered for cantilevered loading.

With this photo through the chain link fence, one can see the flat box hulls in the shape of the stern. The box shape of the hulls allow for the most displacement to be packed into a short length.

Geezer International Canoe Design Redux - IC Fatso

If you dig far enough back in Earwigoagin, you'll suss out the blogmeister's history as an International Canoe sailor. (Though, truth be told, I had more-or-less completely stepped out of the class a long time ago, seventeen years ago, way back in 2000, long before this blog.) The International Canoe's are really great performance single-handed dinghies, and they are proving to be a good fit for top-notch (and I mean top-notch) oldster dinghy-ites who have kept up their fitness and boat building skills (ref. Chris Maas, Robin Wood, Steve Clark, Alistair Warren, Colin Brown and others (many of these skippers I competed against in the 1980's) - though you do need a bit of extra dosh to play at the top level; carbon this, carbon that, jibing daggerboard, T-foil rudder, mylar this, super control that... it all adds up).

What prompted this post was this recent comment by Steve Clark (ruminating after the recent International Canoe Worlds in Pwhelli Wales, UK) over at the Sailing Anarchy forums.:
"The elders are thinking nice thoughts about a little more stability. Remember that the old development rule allowed boats as skinny as the new rules (750mm) and the boat that emerged as "best compromise" was 1014 mm wide. So I had been meditating about what I can do in a beamier hull form. It will probably give something away upwind and in a short chop, but there isn't much slower than a capsized IC. I have an idea, based on Lou Whitman's Phoenix that was probably faster than the Nethercot in 1970, but never got much of a chance after the ICF made the Nethercot the only approved shape."
Being humble as I am (Oh, what the heck, push your brilliance out there) -- I was echoing Steve's most recent thoughts for a oldster International Canoe over ten years ago!

When Steve Clark proposed his new rule back in 2005, which favored very narrow IC's, I, being the maverick, thought - why not have an IC that was 18.5 feet long and beamy -- should end up about the same speed and easier to sail. So I drew this one up based largely on the Whitman Phoenix design. Predictably, there was not a lot of support from the class to add 1.5 feet (457 mm) in length to the IC rule and this design became an interesting but ultimately a dead-end footnote in International Canoe history. (Note this design was done in 2005 - 12 years ago.) (ed. note: The Phoenix International Canoe, drawn up in the 1960's, was a very fine-lined, shallow-V, beamy International Canoe design by American International Canoe designer wunderkind of post-WWII - Lou Whitman.)

Two years later, 2007, I pulled in my elongated, mod-Phoenix design IC into the normal International Canoe length - 17' (5.182 meters) and did a new design, the IC-Fatso.

The sections (I kept a tall bow to hopefully keep green water from sluicing over the foredeck.):

The topview of IC-Fatso:

Maybe if you wait long enough, you find yourself sitting on the right part of the circle as it comes around again ... and then maybe not. Dinghy designs are always food for thought and more often than not, there is nothing new under the sun.

The IC-Fatso remains a design exercise. I've never checked to see if the IC-Fatso would fit the current IC rule (it would be an OK design to the older one). The IC-Fatso would, under most conditions, be slower than the current narrow IC's and the IC-Fatso wouldn't qualify as a Classic (the Nethercott, Slurp are the two designs in that fleet). It would be a safe design that would get you around mid-fleet with less trauma than the current designs and possibly faster than the Classics but it seems to fit in a tweener world - which makes it a difficult proposition to build for the class.

The blogmeister sailing his Nethercott "No Eyes" at the International Canoe Nationals at Lewes, Delaware in the early 1980's. We made it a family vacation that year and, in 2017, some 30 odd years later, returned a second time for a family beach week (no sailing).

Bertrand Warion Watercolors

Bertrand Warion, French boat builder of classic dinghies such as Moth's, 9m2 Sharpie, and the Dinghy Herbulot, is also an accomplished marine watercolorist.

Bertrand's watercolors are now offered up for sale on the Internet. Well worth a look if there is a area on your wall just begging for some boat art.

Update 09/02: This link allows you to preview 63 of Bertrand's watercolors.

While we are dwelling on art, it's worth checking out Trevor over at the blog eh...whatever (over on the right on my blog list). He has a fair number of posts featuring his watercolors. (Though hailing from somewhere in the middle of America, Trevor's art doesn't feature many boats... still very high quality art nonetheless and always interesting to peruse.)

Australian Sailfish - New Build Completed

Brian Carroll, son of Jack Carroll, designer of the Australian Sailfish, has finished up building an Australian Sailfish over the Australian winter. Greg Barwick sends along this photographic documentation of the Brian's boat build. Greg reckons this is the first new build in thirty years. There seems to be a great uptick in interest as the class website has recorded forty downloads of the Sailfish plans over the last nine months.

To put the document into another tab (for viewing or printing), click the pop-out icon in the top right hand corner.

More Australian Sailfish posts from the Earwigoagin archive - including some of the American Sailfish as well.
