Wayfarer: length 15ft & 9", beam 6ft & 1.0". Theoretical hull speed estimated at 5.5 knots. I suppose it would go faster with a frickin' big outboard and no care given to fuel consumption but the weight of the thing would cause problems. I expect.
It looks like a planing hull to me or at least semi displacement. Definitely not full displacement.
how about one of those 7.6 litre V12 outboards
the biggest disadvantage of age .... is that you can't outgrow it
For just idling around on a nice river it is a valid alternative to petrol on small boats.
I became slightly addicted to electric boating last summer when I was able due to circumstances to spend a slightly ridiculous amount of time going up and down various parts of the Thames in a silent electric canoe with voluminous quantities of cold beer.
If hell exists on earth then it was definitely not there.
