makes a nice noncompressible strong core
. It's a really crappy core
if you have leaks
, however. If there is a leak, water
is transmitted along the grain and you can end up with a totally rotten core with just one leak. Balsa, on the other hand, does not wick the water
from the leaky area. It will rot
but at at a way slower rate than a plywood deck.
Westsails, for one, had a real problem with the plywood core on the boats with teak decks. They screwed the teak down with more than a thousand fasteners. Almost guaranteed to be a problem. Most of the new boats are built with the teak epoxied to the fiberglas underlayment so no screws. Unfortunately, the teak is not 3/4" but a 1/2" or much thinner and wears out relatively quickly.
A teak deck would be a non starter for me. Just too many EXPENSIVE maintenance
Teak is a nice non skid because it is skin friendly while being very effective at maintianing traction. To me, it is not worth the maintenance
and problems because of it's total unsuitability in the tropics. The wood deteriorates fairly quickly. A teak deck that is still in reasonable condition after 10 years where the sun shines 7/365 is almost unheard of. Worse, the teak soaks up heat that makes it too hot to walk on and transfers that heat to the interior
. Once hot, it acts as a heat sink that keeps the boat hot well into the evening.
