Question deck delamination

Hello Everyone!,
I am planninig on buying a boat soon and want to know the real chances of having a delaminated deck. I hear so much about making sure there are no problems and this is a common problem on some boats. What is the chance of a boat having a delaminated deck? Thanks a lot, Dennie

There are an awful lot of variables in this. It depends on the manufacturer, the construction techniques that they used, when the boat was built, how it was maintained....

Delamination is not a fixed "fact". My boat is 42 years old and the deck core is bone-dry and rock solid. There are newer boats out there where the deck is squishy and hollow.

The easy answer is, buy yourself a moisture meter and/or pay for a survey. The moisture meter is a good investment in telling you whether or not you should even bother with a survey. At the very least, tapping around with a screwdriver handle or a phenolic hammer will show changes in tone as you tap around, which may indicated a soggy core.

On an older boat with a cored deck it is pretty high in localized areas. A lot less likely that it would be wet in large areas or everywhere.

Your best solution is to buy a good moisturemeter such as the Electrophysics CT-33. Its use will allow you to eliminate wet decked boats before you spend good money on a survey.'

Here's a link to its use: Understanding the Moisture Meter / Electrophysics CT-33 Photo Gallery by Compass Marine at pbase.com

Here's a link that explains how to inspect a boat.

Depends

That depends on the age and construction of the boat and the maintenance performed by the previous owner(s).

I just purchased a 2001 Catalina 310 and had one minor stop of core rot that I need to deal with around one of the stanchions. If I don't address that one spot and let it go, it could turn into a significant issue that could be very costly to repair. However, the whole issue could have been prevented by good regular maintenance (in this case, checking and rebedding the stanchion on a regular basis).

My old boat had a the cockpit floor starting to delaminate, that is one of the reasons we decided to upgrade.

When I was looking at boats I saw some nightmares that would have to be completely ripped apart to be made safe again.

Worries about delamination and core rot are some of the reasons why you should always get a potential boat surveyed prior to purchasing.

I plan to get the boat resurveyed every 3-4 years as a double check that I am doing the maintenance well. It is worth the $500 to me to have someone check my work.

Good luck looking for a boat. Do you know what you budget is yet for the purchase?

Thanks!! Everyone,
Thankyou for the swift responses. I will have about 40,000.00 to spend on a boat. I really like Nor'Sea 27's, Bayfield 32's, and CSY 33's. The CSY's have solid deck and hull so no delamination worries there. :-)

Also, older boats with screwed on teak decks, with a cored fiberglass deck underneath are almost guaranteed to have serious delamination issues unless the teak decks were meticulously maintained.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
