This has been siiting up in my garage rafters for at least three years now.
I can't even remember why it got sidelined. There must have been more pressing short term projects that got the better of it. But all of those are now done with, and it is back on the table.
6'3" x 21" x 3" single fin. I had planned to fit it with a fin box, but now past experience has taught me that over time, and with enough use, these can be a source of leaks. So I will be going with a glassed on Spitfire outlined fin instead.
I used a double internal stringer, instead of a single one, to help minimise twisting of the frame when the bottom skin is being glued on. Top skins will go on next, and then the shaping of the rails will commence. Hopefully I won't get distracted again.
