Just this week the yard just started pulling the teak decks from our 1983 aft cabin 44'. We had significant water coming into our aft stateroom (1" of rain produced about a gallon of water in the bucket) and the teak was weathered down to 1/4" in many places.
We are at about 50 hours into the deck removal at the yard and most of the deck is up. It's required significant hours due to the amount of glue, bonding and screws. Good news is we haven't found any significant damage to the structure. However, they did find some damage to the fuel tanks when they took off the deck fill plates.
Our plan had been to put Seadeck or something similar on the aft deck and Kiwigrip on the lower walk around. Given how exposed our aft deck is, the teak adds a lot to the look of the boat which we wanted to keep.
However, we are being told that the Seadeck material only is available in smaller sections that will requires us to create breaks in the covering as our deck is 12' long in places. So, we are now on the search for an alternative for the aft deck and may just default to the Kiwigrip.
