Re: Polyester mold for epoxy foils

I have done stuff like this as well. I like to fill up as much of the mold as I can with bits of wood cut to shape to make the amount of bog heating up, sagging, shrinking and otherwise misbehaving down to a minimum. I also have been known to make sanding blocks that are the shape of the section and...

Re: Glue

I used .007" Mylar film for gaskets and stuck it in place with double sided tape. I used to use seam stick that I would get from local sail makers until I started covering wings all the time. Now I have 3m 415-4163 hanging around and use that instead. Once the Mylar is glued down, i cover it with a ...

Re: Rules regarding GNAV's and rigging.

Gnav's are legal. So are multiple purchase shroud adjustment systems. There are , in fact, no restrictions on rigging except a ban on outriggers and spreaders wider than the beam of the IC at the chainplates.

Re: AC Developments and boats in build

Of course Steve, always welcome to recieve input and advice from whatever source. Does this mean ensuring the weight of the pole assembly is balanced by weight added slightly rear of the mid point? Adding counterbalance is not as good as reducing the weight in the ends. You want minimum pitch inert...

Re: Designing DC's

Both String Theory and my new boat have about 300mm of rocker... You are kidding.... right? If I read your table of offsets right the mighty String Theory has 72mm of rocker ( just under 3" for imperialists) not 300mm ( commonly known as a foot.)

Re: AC Developments and boats in build

IF you will accept input from someone who shouldn't be commenting on this thread..... Do EVERYTHING you can to keep the LCG ( longitudinal center of gravity) as far aft as you possibly can. You have lots of structural efficiency available by putting the pole on center line and, You should maximize t...

Re: Designing DC's

The Second String design definitely has both bottom of the stem and the bottom of the stern underwater when at rest. You have to get well forward in light air to stop the stern from gurgling. As soon as the wake starts to break away cleanly from the stern, you can move aft, the bow comes up and she ...

Re: Designing DC's

Correct. For 1/5 scale: divide linear dimensions by 5, area dimensions by 25, volume dimensions by 125. Or stated more generally: by the scale, the square of the scale and cube of the scale.
Looking forward to seeing the design!

Re: fore and aft rails advice needed

Ian You don't need to play with stainless. Around here we have been happy to use 3/4" x 3/4" x 1/8" channel. If the backup is appropriate we screw this to the deck. If not we bolt it. Something like 4" between centers. ( all in Imperial measurements, sorry but don't know what the off the shelf sizes...

Container From USA to Germany

We have the opportunity to ship ICs from the USA to Germany early in 2009. We plan a 20' container with Roger's GER 78 and Peter's new Chris Maas canoe. There is room for 4 more ICs, so if anyone is interested in acquiring other US boats, this would be a great opportunity to get them across the ocea...

Re: GPS onwater training tools

I sail with a Velociteck about half the time. The speedo gives you some instant feedback on what the speed gains/ losses are at different headings, which helps you learn where the go buttons are hidden. The logging function gives you the opportunity to review the sail and form a better opinion of yo...

Re: Designing DC's

This is another one of those areas where our little bit of the sport has eluded the benefits of research. Quite a lot of work has been done on planing motorboats and been paid for by the navies of the world. Not much has been done on double curvature shapes that are pushed from a center more than 6'...

Re: Designing DC's

I don't know if any sailboat really planes in the classic powerboat use of the term. Certainly there is a regime where the hull raises out of the water on dynamic pressure instead of being sucked down as true displacement boats operating above their hull speed are. But unless you have some fancy flo...
