The underlayment of teak decks on Tayanas is built up of softwood
squares individually isolated by dams of polyester. If such
underlayment does get wet it usually doesnt not spread accross the
whole deck as would be the case with ''sheets' of core filler.
Not that you cant get a soggy deck on a Tayana; but, if you do the
damage wont be as catastrophic as would a deck with continuous
underlayment filler. Teak deck maintenance isnt all that bad if you
kkep up a gentle and consistent regime of maintenance. Hell, I bet you
expend more time scrubbing a glass deck than a teak deck owner does in
periodically looking for loose bungs.

Give me a teak deck anytime. So what if it makes the boat a bit more
top heavy, **nothing** is this world has the non-dkid ability of bare
teak.
