Medicare Part A

Today I went and registered for Medicare Part A, which, if you are a knowledgeable American, would precisely date my age. To celebrate, given my temperment, and to what I can look forward to in my coming advancing years, I present a somewhat Anglo-centric but very prescient video. (Let me also state that I work approximately five miles from the longest escalator on the East Coast of the U.S - and I have yet to take a ride on it... bucket list!)

Johnny Z's Classic Moth Mistral Build Reaches the Finish Line

John Z. put on a late summer push to get his Mistral Classic Moth build finished for the E-City Nationals in mid-September. I went over to his place to take some photos as he screwed in the last fittings.

John has installed a 16:1 cascading vang.

The carbon mast is free-standing with a forestay which provides positive rake control.

John used the Ronstan sheaveless blocks for his leads at the base of the mast. Simple and light. I pulled the strings a bit and they seemed to slide fine.

John doubled up the ply in the seat area to support him crashing around and sitting down heavy on the tacks. The carbon boom was a discarded carbon oar from a rowing shell.

John glassed some ears on the boom and then attached it with a through bolt on the mast. 2:1 on the outhaul is external.

John used foam deck pieces from the SUP crowd for his non-slip in the cockpit (comfortable for knees as well).

Benoit Duflos' Moth-Pop, Construction Plans, Part 2

Detailed dimensions of the Moth-Pop Moth Classique are in Part 1 of this series.

Here is a short PDF showing the construction details of building the Moth-Pop upside down over the flat deck. Use the pop-out icon on the top-right corner to put the PDF file into another tab on your browser. From there you can print or download.

Benoit Duflos' Moth-Pop, Moth Classique Plans, Part 1

Construction details for the Moth-Pop can be found in Part 2 of this series.

Benoit Duflos was the designer who, in the 1960's, introduced the narrow waterline, very V'eed Moth design that would prove to be the fastest Moth design of that decade, the Duflos ruled the roost until the class merged with the Antipodean scow fleet and adopted wings. Until George A, the USA Classic Moth plan librarian handed me these plans, I hadn't realized that Benoit also designed a more stable design, specifically for home-builders. Benoit's design, the Moth-Pop (no idea where he came up with the name) is a flat-bottom design, in the tradition of French dinghy designs, Staempfli's Sharpie 9m2 and, Herbulot's very popular Vaurien dinghy. It is designed to be built upside down on a flat deck using three bulkheads, a small bow transom and the normal transom. Starting at the front of the cockpit the flat bottom transitions into a arc'd V toward the transom to reduce wetted surface. There are probably a couple of Moth-Pop's still sailing in France but I have yet to come across a photo of one

I have taken a couple of JPEG's of the plans which can be viewed or downloaded. Use the pop-out icon on the top-right corner to put the image into another tab on your browser. From there you can print or download the file.

In this first side view image we can see that:

  1. Stations b, c, d and bow transom (1a) and regular transom (8e) are the bulkheads that Moth-Pop is built around and stay with the hull after completion.
  2. The bulkheads are set up on the flat deck with a backwards angle (angled towards the transom) as shown by the arc Benoit has drawn at section 1a. This is to keep the bulkheads perpendicular to the design waterline.
  3. All dimensions are in cm. (mm are indicated as a superscript to the cm dimension) unless it is a single digit, which is mm.

Below is an iso view of the underside of the Moth-Pop deck. Benoit has the builder plot the sheer and cockpit dimensions on the flat piece of plywood deck before placing the bulkheads upside down.

The section plans. Note how the bottom becomes an arc as it transitions toward the transom. Benoit has written the metric dimensions on the plans which can be viewed when zoomed in.

Header Photo: Mariposa Again!

As far as I know this is the first sailboat to be featured twice in a header photo. This is Bertrand Warion's Mariposa, a French design Classic Moth with the sauciest sheer (hence the most photogenic) of all current Classic Moths. (Plus I'm partial to lime green as a hull color.) This is the second iteration of Mariposa. Bertrand Warion decided to change the interior of the original Mariposa over to a double bottom (an idea he has since back-tracked on since he is a tall fellow and he felt somewhat cramped when he took away some of the room for his legs).

No matter. This still shows the room for experimentation in the Classic Moth class with probably the most roomiest interior going in the Classic Moth. The trade-off? The tiny gunwhales are definitely not a comfortable hiking platform.

House Chores

I was vacuuming one of the side bedrooms in our house and came across two small pieces of paper on the floor. In picking them up, I discovered they weren't scrap paper but thumbnail prints (most likely cut out from a contact sheet) of the blogmeister sailing his Laser out of SSA (Annapolis) back in the 1970's. They must have fallen from some book I had re-shelved. I don't know who took the photos. (Warning! Blogmeister with hair and beard)

It looks like it was a gusty northwester as I was sailing upwind towards the U.S. Naval Academy.

Nobody had invented flat leg hiking yet!
