Check the Bristol Owners web site. B-32 models have solid decks, but I can confirm that Any older boat in the 15k price range is going to need upgrades.
Also there two Yahoo groups for people interested in Bristols.
And Yves G [of Cape Horn Wind Vanes ] took his Alberg 30 around the world in 1983, and has owned the same boat for 37 years.
Good hunting, Ken S
