Re: *Increasing* plank friction!

Usually the supper sliding seat is caused by having a fit that is too good. The seat needs to point load in order to stay in place so usually the first best move is to increase the gap between the seat and carriage so it rocks a bit in the carriage, this makes it "jam' just a bit and stay in place. ...

Re: Centreboards ans Rudder shapes ans profiles

Jim, it is probably a mash up of a number of different theories that I have got hold of part of but not all of them. and then it's a way I can describe what I see happening around a hull and do something about it. I guess the source is the Whitcomb Area Rule, which more or less says that the volume ...

Re: Centreboards ans Rudder shapes ans profiles

Airplane wings operate in a simpler environment. Plan form is one of the really obvious variables, but probably one of the least significant. Symmetrical shaping, area and section choice are all a bigger deal. I think practicality trumps any small improvements that might be made. Although we certain...

Re: Balstrom rig

Rod Mincher famously tried a swing rig in 1987. The tale of misfortune is classic reading and is somewhere on the web or in the Canoesletter archives. His problem was that the main leech would load up before the jib would fill and the boat would spin out and stay in irons. This could probably be sol...

Re: Rudder pins

It is hard to discuss rudder shafts or pins without thinking about the shape of the rudder you hope to build. My current thinking is much influenced by others in the sailing world who have gone for deep high aspect rudders. If these are to be anything but very thick sections, you need to make the sh...

Re: How to make a new foredeck?

I cut plywood about 25mm big all the way around. I drill holes in the part that hangs over. I have a pile of hooks made of bent nails that I stick in the holes. I pull the deck down with rubber bands made out of old inner tubes. It helps to pin it at the front and back of the centerline, a brad does...

Re: Board Length

The 1 meter span was on the tablets the bearded bloke brought down the mountain..... While draft restrictions make about as much sense as rig height restrictions, these have been with the class for a long time. The boat may be better with deeper boards, but no one has particularly thought to try the...

Re: K136 The Rebuild

The hollow back deck serves two pretty good purposes. It lowers the CG of the helmsman and makes the boat more stable when you are moving around on the deck. This matters more than you would think. Canoes that have been built with flat aft decks or even crowned aft decks are harder to sail and are l...

Re: Rudder pins

I would stay away from pultruded glass rod and stay with 12mm stainless. If you have a larger rigging shop near you, you can often get cut offs of Nitronic 50, which is the alloy used on solid rod rigging. You will need cobalt drill bits or a friend with a machine shop, to do the drilling for you, b...

Re: Congratulations

Funny about the IC AC handicaps. We sailed a handicap regatta in Ottawa last month using the PY 873 for the ICs. Oliver won over a fleet of fairly competent Contenders, which seem to be able to sail to their handicaps fairly regularly. There was one RS 700 but it was not well sailed, and not much el...

Re: Relative Speeds

We just completed one of our only North American regattas where they do anything like a reasonable job with handicaps. The ICs were assigned a PY of 873, which is the same as the AC. Our primary competition was a group of Contender sailors from Toronto who have good, up to date boats and sail them w...

Re: How to...Check for watertight seat

Unfortunately having the seat fill up with water is a good way to have a very bad sail. So some attention to this detail makes your life much much nicer. The best way to assure that you have a watertight seat is to see if it holds pressure. I use something like a water level so I can see if the seat...
