Right on Nugdam ;-)
I have got a few go on my new longboard 9'2" 28" 114litres that goes well, but I would better get an 8'10 29". Because I would have the easy life paddling, wave entry, bottom turn crank, forward stance to nose-riding, and one important feature to be not cumbersome to zigzag through mates down the line.
Here below are the dims as they are by now (9'2" 28" 114litres), and the next one shortens to 8'10"29" 114 litres.
Here are pictures of the actual 9'2" that I want to reduce to 8'10''. I will erase the channels and do a carbon lamination instead of the three wood stringers with glass-also, no more step Deck but thinner the front rail to secure nose riding manoeuvres.
