Re: Finisning and Fairing

One of the advantages of using a prepackaged filler is that the stuff is all the same density, so it will sand evenly. If you start mucking around adding balloons , you will change that , and the fairing compound won't fair evenly. The filler loading also effects how the stuff shrinks, s0 it is usef...

Re: Movement of seat carriages

Colin: The tongue and groove seems to work as well as anything I have ever done. And I did the many wheels thing that Chris describes but with $14 a pop ball bearing wheels. The slipperiness can be tuned with the selective use of Mclube or Teflon lubricants. I can slide the carriage fore and aft whe...

Re: UK Boats in build

I don't want to stand around declaiming that I know all the answers, particularly here where there are many whose work is commonly regarded as superior to mine, but I have built a few things that were OK, so a tip or two. I have no problem co-curing the outside skin, the core and the inside skin. Bu...

Re: UK Boats in build

I have done it both ways, there are compelling arguments on all sides. I haven't noticed a big difference in the weight or the part quality, so suggest it is mostly a question of how much manpower you have to do the laminates and how good are they. If you don't have the horses, take the extra steps....

Re: UK Boats in build

Not in the UK, so not relevant, or even up to the standard of excellence.... but 5 more sheets of plywood have been fed to the Laser Cutter and these will turn into new boats for David and Me. These are certainly upside down, carbon composite decks on plywood hulls. There are some fun ideas we are e...

Re: mast bouyancy

Last go round in the states, we tried using a sealed masthead with a peg that stuck out the top for mastheads. These were left over Optimist sprit ends, and we didn't have time to make halyard sheaves and halyard locks. We have to tip the canoes over and pull the sails down from the top and slide a ...

Freight to Keil Germany

I am sending a C Cat to Keil Germany. This will not fill the container, so there may be a possiblity to get other stuff from RI to Germany at this time for a contribution to the cost.
Like AUS 18 or some of the other very tasty east coast ICs and Nethercotts.

Re: Hullform development article

Bill Beaver did full scale tests last winter. The results were reported in Canoesletter #29. I think this was distributed to someone in the UK via the Internet. I suggest you contact either Bill, John Kells or Willy Clark to get web worthy copy. Results were not surprising or unanticipated, but actu...

Re: Rig Tension - modern IC's

Using a stress level of 2500 psi for wood, and a guestimated compression load of about 2000 lbs, you something like two square inches of cross section to hold the mast step up with a reasonable factor of safety. The mast steps loads need to be spread into the skins. In practice, I put 6mm plywood un...

Re: Rig Tension - modern IC's

I started with the chain plates about 330 aft of the mast CL. I felt that while the fore stay tension was fine, the mast was not being supported well athwart ship and successively moved the shrouds forward until they are now about 290mm aft of the mast CL. One advantage of wide chain plates is the a...

Nice Tim Wilson IC/AC needs a new home. Silver hull, bright foredeck. Tim Wilson ( knows better than everyone) spec and construction. CST mast, Alexander Sails, Fastercraft foils, Aluminum trolly. This boat hasn't found a home in the US and probably isn't going to. Best deal will be to ship her to G...

Re: JIB BOOMS

I have solved this two ways: First I increased the uptake inside the seat. There was enough friction in the bushing at the end to tack the jib, but not so much that I couldn't yank out extra scope for the runs. Second effort was to put a block on the bungee and lead the sheet tail through the block ...

Re: New IC's

I have done a modification of Kaito,( the 3rd josie.) The section curvature and chine radius in the front 2 meters has been increased and the little tuck aft of the rudder trunk has been straightened. The result looks far more normal. I anticipate the boat will be a bit smoother in a chop and trim l...
