Back to jockey consoles then: ribtec 3 man is as follows:
width at bottom 14" (plus 1.5" flange for glue and self tappers)
width at top 11.5"
then a foam seat 7.5" high, semi circle in shape made in hard foam mounted on a 0.75" base of Oroko. You can buy the semi circle foam in long lengths and its about 11" wide at the base
This console is for 2.5 - 3 people. If a mould was made for this size, one man consoles can be glassed by putting in a fillet say half way along and just glassing just half a console. Pasticine is used to fair in the fillet. Osprey used to recon 20 - 30 hulls before a mould needed to be replaced. Seems resonable. Hope this helps the debate. Pete
