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
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.
decks on older Ty37 may be a 'problem' if they werent metcullously maintained. Look for a Ty37 without a teak deck
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.
