Teak deck on steel hull and deck, great mistake..

YES ! And unfortunately it is the "rule" for Nederland boatyard...
We had :
one 12m De Alm we remove the teak
one Doggerbank 18m Vripack ...don't keept her long enought but the teak must be removed.
the actual : we removed the teak
The only advantage for the teak is :
in winter better insulation (but not in summer because the teak warm up more than the white plating)
and less noisy when raining

I would almost 100% agree with you @balder8, except I would say “Teak decks, great mistake…”

No more for me, that’s for sure, but perhaps my experience was worse than most because they were teak planks over steel frames. No sub-deck.

Our second boat was even worste be aussi they put teck deck on wood beam on...steel deck and steel beam !!!
It is the worste water stay between this big gab until the rust make à hole on the steel deck..when we bough her they already remove the teck, remove the steel and fit CP with fiberglass...This boat built Germany with 'only' 20 year old was in very bad shape must replace 29+sqm of the hull, including structure...

Except it isn't a steel boat, it's aluminum.

Except it isn't a steel boat, it's aluminum.

True, better than teak on steel but still subject to corrosion from trapped seawater.

I know that, I already contacted the owner to know if he could be interested by an 'exchange" with our bigger one...
But the problem on alloy boat is similar than on steel .It is why our first job on our actual was : remove the teck from every where !!
We miss the sale because the teck was removed, the customer bough à prestigious brand from Holland...and now he understood why we remove the teck, he already paid for rekaulking all the teck and ...still have problem

Teck deck only on fiberglass or ...wooden boat

Another point remove the teck save around 600 kg at an average 2m above wl

There is a lot of concern about how the teak is applied to the steel deck.
My father-in-law built a ship himself 47 years ago and equipped it with a teak deck.
First, the steel was well preserved, then polyester with a glass mat was applied and approximately 10 cm extended against the cabin.
On top of that the teak wood is applied with sealant (Saba)
47 years later, the teak is still in new condition, no leaks or rust anywhere.
It is a very laborious method but will last at least 50 years without any problems, even the sealant joints are not yet in need of replacement.
The teak deck is 2 cm thick!
The ship is always on saltwater.

Mvg,

Pascal.

Finally you arrive at what I said : teak on...fiberglass
When you wrote "even the sealant are not ..." I am very surprised because for example on the Moonen of my friend it was already done twice, on our Doggerbank at only 19 year old idem for our De Alm ( 8 year old )
May be in cold and not sunny country ?
Because for example the motor sailor Tangier (we already discuss about this boat here) she also had very tick teak deck but after few year under the tropicals sun some sealant need to be replaced.

On our second boat (photo above) they also put fiberglass on cp and inside the bulwark....the adherence on steel was not perfect ( but ok it was 50 year ago may be now better product...)

The deck is kitted with Saba, is the best kit available (was)
I don't know what raw materials were used in this kit at the time, possibly they may no longer be used now.
It is certain that it is a very good kit.
I have used Sikaflex myself, which I am certainly not satisfied with, after 23 years I have re-caulked the joints of the deck.
For gluing I think the 212 from Sikaflex is very good, for the joints I now use Bostik, apparently the replacement for Saba, time will tell.
As for teak decks, if you want to be beautiful, you have to suffer pain!

The ship is always in northern Europe, the sun is the death knell for everything!!
