Black iron tanks are NOT a problem if you keep the water out of them and keep them clean underneath .... free from mud and
anchor 'dribblings'. A simple reciruclation/polishing filter with a water knock-out-pot or 'leg' will separate the water from the
oil. After all, refineries use black iron for their field
storage tanks !!!!!! Black iron is easily repairable. If the black iron tank wasnt maintained, you can cut the top off and install an
epoxy fiberglass liner - using a
fuel compatible 'tank resin' etc.
Most older Tayana 37s are now uncovering a lot of chainplate base problems - soggly bases that need to be bebuilt. Make SURE the
surveyor removes the chainplate base fascia boards and actually LOOKS at the chainplates and bases. If the bases are wet, the the 'non-removable' attachment bolts are subject to crevice
corrosion failure.
The chainplates have a design flaw that makes the plate prone to fatigue cracking ... 'beefier' (and polished) plates or changing to external plates is the remedy.
Teak decks on older Ty37 may be a 'problem' if they werent metcullously maintained. Look for a Ty37 without a
teak deck.
The
bowsprit is made of laminations of teak and an 'asian' mahogany.
Rot will be found in the 'mahogany' but not usually visible from the 'outside'.
No two interiors will be the same as they were / are 'semi-custom' and built to the original owners various tastes. For
offshore sailing look for one with 'sea berths' or a quarterberth, avoid a 'pullman' berth arrangement. A lot of interiors were oiled .... and now look like 'caves' due to the 'darkening' of the teak and the oxidized
oil finish; try to find one with a varnished
interior.
Avoid the older boats with wooden spars, from about 1980 onwards they used
aluminum spars. Much of the
rigging is "Grand Deer" and includes quite dangerous rigging toggle bolts that are NOT forged, but are a machined screwed-together affair .... very dangerous and subject to crevice
corrosion failure. Replace with forged toggle bolts.
A lot of the OEM winches are 'exploding' Barients. The identity is they have a 'plastic' split top flange and have a 'push-button' release inside the
winch handle socket. They can fly off the spindle without warning when under high loads. Obviously never go up the
mast hanging on a 'push-button' release
Barient.
Blister are not a problem. However, if the sun exposed
gelcoat hasnt been regularly waxed and buffed, you may find the beginnings of 'microscopic' 'alligatoring' - a precursor of complete
gelcoat failure. Take your strong magnifying glass or (Radio Shack) pocket microscope along with you.
A Ty37 is a wonderful and 'seakindly' sailing boat, built like a tank that can carry a huge amount of cruising stores. The higher the
wind speed, the bigger the smile. They are a bit 'top-heavy' and have a slow roll period (I power-puke on a boat with a fast roll period). I'd buy another one.
