Aloha and welcome aboard!
Good to have you here and sailing again. I owned a Mariner 35 wooden ketch designed by Bill Garden. The Fuji 35 is much the same but has a fiberglass hull
where mine was wood. My '67 model was built in Yokosuka and there were many delamination
problems in cabin
top, transom, cockpit
and decks for many of the Mariners. Mine only had a bit in the transom which was easily repaired before I sold it in '86.
If the construction of the Fuji is all glass then it would be a toss up. The Pearson will outsail the Fuji though so if that is a priority then that's the way I'd go. Also if the Pearson is a sloop there is a lot less rigging
to mess about with when it needs to be replaced.
I'd compare engines and accessories and condition of rigging
. I like the old style of the Fuji and it it's a ketch the many sail options especially the mizzen staysail but I appreciate the performance of the Pearson.
Good luck in your decision.
