Please!!! to ALL who have a
boat < 1990. Do NOT remove the good old naturally grown
teak with 15mm which is usually grinded down by some destroyers to 10mm.
If you want to know if you have natural
teak: hammer down a 3 mm nail about 10/10 mm from an edge. Natural teak will not split while plant teak will.
Rework the notches - replace, reset the screws deeper and reepoxy them and - for hell - grind in once again. By then NEVER apply
paint or teak
oil scrap! If possible wash it at least weekly and only with
salt water and a soft brush.
It take years until the flat surface gets rugged but this is what it should be. A real glossy surface is stupid as you have to grind down every 2 years with at least 1 mm.
Applying a new
teak deck you get new plant teak which is uzsually only 10 mm and only 1/3 as tough as natural ones. With plant teak please expect to replace it within 15 to 20 years. Natural teak that is treated properly will last, without unnecessary grindings up to 80 years if it is, after 40 years now, grinded down to 10-11 mm.
Even if some
plywood stuff is rotten... the
deck will be usually strong enough and hell it is a good old
boat. And it will dry out when the screws and notches are properly repaired.
p.s. teak is one of the best
wood to withstand the sun = loosing lignine very slow and if the
deck is rough and silveer/grey the surface is ready and prepaired to face the sun without lignine loss at all.
But usually spoken against the
wind.
It's a pity.
