Fine folks at Trawler forum...
I am back here looking for advice, as our five year old dive boat ages, of course the problems start.
The boat was built here in Vietnam of some unknown tropical hardwood.
One wood for the hull and another for the deck and upper works.
The decks are about 7/8 thick, shiplapped, between the boards is a V groove about 3/16 by 3/16 the of an inch.
The sealant between the deck boards has failed, of course....
any kind of sealer that was used locally has been in use for hundreds of years and is not a urethane caulk of modern vintage..
I am being told locally to open the grooves, pack them with fiber, and fill with some kind of pitch, which is how the hull was done...
I would like to bring us out of the dark ages and into modern times with this project.
Your recommendations for a suitable product will allow me to research what MAY be available here in Vietnam, bearing in mind that they do not have bilge pump float switches, nor on demand pressure pumps...
They are building modern high rise buildings in Saigon and Hanoi and as a carpenter by trade, I know we use urethane caulks in buildings, so it JUST may be possible to Sikka or somebody similar is represented here in Vietnam.
Who makes this stuff and what products might you recommended ? also I expect we will have to up size the grooves, so I will get manufacturers recommendations for that part.
some photos of the deck can be found here..they are high resolution so you can zoom way in.
Thanks very much for your help and advice...
FYI..Dealer networks do not exist here, there is no amazon.com there is no advertising, no marketing...it took me 2 DAYS and visits to over 100 shops to find c cell rechargeable batteries....My wife..Vietnamese and smart, could not find freaking wooden hangers in all of Saigon . I managed it, by going into a tailor shop and asking where they got the hangers..
Thanks very much
