i have a 41 coronado bigger version of the 35. and for the most part they are solid but just like any vintage boat they will need refitting. give the hull
below the waterline a good look its balsa cored which isnt a bad thing as long as the previous owner didnt improperly install/seal through hulls or penetrate it for any reason. these boats usually have soft spots on the side decks due to leaky coaming boxes/ holes that drain into the end grain balsa. not a difficult repair, just finished repairing mine. inspect the keel bolts
if original there probally in bad shape. i dont believe there was many problems with the h- joint all the columbias used them too. if it has a palmer you will want to upgrade to a diesel
. if it has the albin diesel
are hard to find and expensive i heard. there is some negative comments about coronados dont believe the armchair bashers. theres a ton of them still sailing mine has crossed the pacific and cruised all through the carribean
to the north atlantic. if shes not in bad shape you could easily put some work
into her and have a great cruiser.
