Reply To: Wooden boatbuilding
So after some delay while we voyaged our yacht ‘Hoppetosse’ to the Baltic and then waited for warmer weather the ‘Hoppetosse’ OK is taking shape. I have filled the jig with marine plywood and epoxy and the bulkheads are all cut out. It is still not certain whether I am building an ‘International OK’ dinghy , a just a ‘boat’ but I live in hope.
Not counting tools I am well within my miniscule budget. Just burnt out my battery saw, and the answer to the question ‘how many clamps do you need? is two more than you have got)
But now I come to my next dilemma. Stringers or what?
If I am understanding it correctly, the new rule change allows 4mm of extra plywood over an area of the cockpit. Perhaps not the place to ask here why the 6mm shown on original plans is not allowed but….. as a fat person I am worried about the stiffness of the cockpit floor and the fact that I stupidly put the scarf joints under the middle of the cockpit.
The Pictures of the Dan Leech boat that I can find shows one ‘stringer’ each side.
My thought was that on my hull made from 6mm plywood, a total of four stringers each 50mm wide made from 9mm plywood at about 100mm centres run through the boat would be good, and relatively comfortable but maybe to heavy? My O’Donnel Grp composite (1840) has glass over foam stringers at around this spacing.
Or should I go for one or two 20 x 20mm stringers each side? Any suggestions gratefully received.
