I agree that it does "Fall nicely on the eye", I think its just the centre section of the keelson thats terminal. Any previous work which I think from the description was about 90% hullsides and a complete rebottom appear to have been done well hence the current "Shape". where do you envisage a cost differential in maintenance Alan, I am obviously nearer to wood than steel but even so I intincively presume an easier life with timber, unless you are completely dependant on ouside labour for maintenance. Water ant timber are naturally compatible Steel is a "manufactured component and doesnt belong submerged or exposed to water so you are in a conflict of interests from the outset with a steel boat.
