First, there have been several requests for the little double enders vital statistics.
Sail area is 7.1 sq m. Thats 76.5 sq ft.
Length is 4.45 m – 14ft 7in
Beam is 1.55m – 5ft 1in
Weight should be around 75 kg 165 lbs
Draft 175mm board up 7in
1.1m board down. 3ft 7in
I dont expect to have to build a proper boat trailer for this, I figure that I will be able to just lift the bow up onto the end board of a handyman trailer, pick the stern up and push the boat forward.
I’ll put plastic imitation grass on the end board to make it slide, and will slot the board to take the skeg which will make it stay centered as I push it.
Managing it on the beach will be with a couple of inflatable sausage shaped fenders used as rollers.
sometimes ones frailalties get in the way.
advice and just build when I feel like it.
No pressure, and it makes it much more fun than trying to meet
deadlines.
only the second meeting of a brand new club and it being a new group means that
the social structure is not so entrench and I’ll fit in more easily. I used to play several instruments, ( badly
but enjoyed them) and should really get one or more out and practice. This will
be an incentive.
great deal of technical and non fiction, writing fiction is very different and
I’m doing a little of that for fun and to make friends here in my new home area
as well. There is no need to be lonely.
daggerboard. Its three laminations of 9mm plywood which is easier for most people than making it up from strips of solid wood.
shape up where it transitions from the rectangular shape that fits the ‘case,
to the foil shape and rough from there down to the tip with a power plane. Next is the hand plane, the dark glue lines
of the plywood make it easy to get the section constant all the way down, and
its at this stage that I go from “eyeball” to fitting the template that I’ve
made from the foil section I drew on the plans.
I got from a hydrodynamics software suite that I have, its designed for high
lift at moderate speeds and to have a very high stall angle, the aim being that
it wont stall when tacking at slow speeds.
styled boat the fact that its double ended means that it will be slower than
boats with near parallel sections from the widest beam aft, that plus even a
really fast small boat is not fast in terms of true speed through the water (compared with say a 70 ft ocean racer) so the medium speed section is more
appropriate to the use.
Laminating the three layers together, use whatever happens to be handy to put pressure on the glue lines.
sander then coat the ‘board with System 3 fairing compound and carefully fit it
to the template.
leading edge by cutting the middle layer of plywood back 20mm and laminating a
piece of mahogany in there. That will reduce impact damage quite a lot.
took about an hour, the rudder blade is next…
