Minion type sup dimensions

Hello Swaylocks, been away from here for a good few years now.  For one reason and another I haven’t built a compsand (or any other board!) for about 3 years.  I have been paddleboarding for some of that time and really like the look of the Minion boards by DEEP ocean.

My next project is going to be an 8ft minion (Tomo?) type, short parallel rails quad fin channels etc.

Carbon Kevlar (corecell)deck, eps core, balsa glass sandwich bottom.

Have built a few carbon bamboo paddles (photos to follow) and now need to start the board.  I think I have the rocker numbers sorted, but was wondering if anyone cpould give me some pointers on fin positions and nose, tail widths and whether the triple diamond tail is really any better than a square tail!!

Thanks in advance

Mark
