Just second hand info I have- I have spent my time sailing beach cats and the occassional ride on a Columbia 22- a friend had a motor sailer he sailed out of Melborne, FL said he regretted selling his Columbia since it took so much wind to make sailing worthwhile- his typical trip was from Melborne to the Keys in August. I've subscribed to Multihulls for several years- the Prouts seem to go for low prices since they are pretty old- but they seem to stay in use.
I've replaced a lot of parts on my 20+year old beach cats- having a cruiser that old would require a lot of faith in the builder- and previous owner(s).
