I have a
Tayana 37, but no experience with the Hardin. I consider myself pretty objective and while I like my
boat, there are things that I take issue with, too, although it sounds like some of them have been "solved" already in this case.
The pluses for the T37:
-- Does exceptionally well in light air. It's counter-intuitive for some folks here, but she has a pretty generous SA/D, which more than makes up for the modified full
keel.
-- Very comfortable motion in a seaway. Hands down one of the most comfortable boats I've been on.
-- Tracks well when
sails are balanced. I was on a broad reach this summer in the Chesapeake and tweaked the
sails until I was able to leave the
helm unattended for a good hour. She sailed herself.
The cons:
-- If yours has black iron
tanks, you need to replace them.
-- Chainplates. You need to make sure they've been checked and/or replaced.
--
Weather helm. If you aren't a "tweaker" and reef early, the Tayana can be a bear on a beat in anything above about 15 knots. Bob Perry has admitted that the
mast (on the
cutter rig anyway) is about 12-18" too far aft, causing "excessive"
weather helm. It's tameable, but you have to know the
boat.
Having said all that, I would say that it's the better boat, especially given what you've said about the Sea Wolf.
-- ADD: whoops, see you already purchased the Sea Wolf. Congrats! It'll be fine!
