That's really cool. Looks like a stressed skin with pretty substantial bulkheads. What made you settle on 150mm spacing on the bulkheads?
Thanks aeroengr, The 150mm spacing is for the mould. In the actual board it is generally 250mm spacing (
infinity1971.bitbucket.io/#table:board-stations) but with some closer spaced ones on the fin-box and centre-box. For the internal frame I didn't have much to go on so took conservative approach and probably could increase spacing given the stiffness of the skins.
Sandman, Chris, The weight is 16.9kg (
infinity1971.bitbucket.io/#sec:weight). I think if I did it again I could get it down to 15kg. The weight relates to aeroengr point about "substantial bulkheads", I deliberately over-engineered the board structure to ensure I had something which I could rely on and would last. Although according to this
infinity1971.bitbucket.io/#fig:lechner_facebook_05 the original Lechner was 18kg (hollow too) so 16.9kg isn't too bad.
Chris, I'm using twin-cam freeride sail (
infinity1971.bitbucket.io/#testing-the-board). I have the sail below ~1990 and is tight leech, maybe I should give it a go for comparison?
