The older Prouts now go for 50k sterling. 100kdollars. NO OSMOSIS
on an old cat a very few structural problems. Surveyors know where they are. They are heavier than a modern boat and undermasted.
Ron Underwood (original Prout director) would be happy to put a mast
up to 10% longer on most of the Prout boats and having experimented with more production boats with forward masts finds there is very little advantage and some major minuses. One of these is lack of stay sail, the storm rig and also aerodynamic slot maker to whatever you hang out front. Like the flaps on a Jumbo that give more lift
for a bit more drag.
The Prout's also carried sturdy, shallow long keels to give the boat a much better range of balance. There have been comments about Mahe 36
falling over on it's shorter keels. Note there's no skeg on the rudders either tho' it's good to see balanced area rudders taking most off the load of the linkages.
