Someone PM's me in regard to a Pearson Renegade they are going to look at today. I am unable to repond directly to PM's since I have not posted enough on this forum.
Renegades are very solid boats. Most of what you need to look for is cosmetic. Gelcoat spiderwebbing on the coach roof is common. Old rudder shafts develop a lot of play. Check all installed gear, batteries, motor, sails, head and rigging. My Renegade had minor gelcoat blistering. Water in teh rudder could be a problem, but it it hard to check for unless you take it out. (it is a foam filled fiberglass.
These boas sail very well, obvioulsy not very light or with as much beam as newer boats. Nice boat for two.
With a boat of that age it will all depend on the attention and effort of the previous owner.
