Hi Andy, yes you are right, I got ahead of myself on the prop and rudders as I thought to build a Perkasa to start with. Then as I got more info on Vosper boats, I had a change of heart. I have moved the props and now have the standard three rudders. This whole exercise started with a Precident kit, but I gave up with that and the hull is now scratch built as the kit does not bare any resemblance to the original.

P.S I got an excellent set of plans from John Lambert today, looks like further mod's are on the cards
