As you can see from the following photo’s 50 years is a long time for a wooden boat to survive intact but such was the Souter workmanship most of the boat is in very good condition…Main areas of repair at the moment are the Transom which has been totally replaced due to the over large Mercruiser transom plate that had been fitted, in readiness for the retro fit of a Volvo Penta outdrive unit..and the bow area where rain ingress had rotten the ply laminations. We are awaiting news from the States about Walt Walters original plans which cannot be found at the moment but believed to be still in Walts posession. One unusual feature is the 6 compartment open top fuel tank built into the keel and glassed in! the cover for this is long gone by the way, then behind that was another tank in copper. These tanks were obviously used firstly when she was racing as a circuit boat then capacity was enlarged for offshore…having seen early film of the craft we realised she had had several cockpit layouts but the driving position was always at the rear. The problem facing us is which layout to use as in her last reincarnation as a speed boat the steering had been moved to the front cockpit..but we have a cunning plan! Photo’s will be added as the rebuild progresses.
