http://www.yachtsurvey.com/moisture_meters.htm Ah yes, David Pascoe, purveyor of misinformation about engines & hater of cored laminates. This seems to be one his less whacko essays, but on the whole I am dubious about much of what Pascoe claims. The best way to find how much water is in the laminate would be to cut it open & look directly, as Matt Colie suggests. Since fiberglass can be repaired to be stronger than new, if you *really* wanted to know, this would be the obvious course. Another way would be to put the boat into a giant microwave oven. Most people don't want to know that badly, so one wonders why they claim to attach so much importance to trapped moisture in their hulls. Fresh Breezes- Doug King |

Dave wrote: Dunno about hulls generally, but my understanding is that in the case of decks it gets pretty expensive to do the repair if you let them get spongy all over. Sure, but are readings in the deck liable to be false from the boat being recently hauled? That was the *big* *issue* Pascoe was raving about. Also, delamination and/or rotting wood core in the deck is detectable without using a moisture meter... actually, cores can get delaminated from things other than water saturation. DSK |

Dave wrote: If it's just delaminated without being moist, you're looking at a much less serious problem, methinks. Why? Delamination is delamination, big reduction of structural integrity. If it is due to moisture, then it could be a bigger job to fix because the you would want to fix whatever let the water get in, as well as perhaps rebuilding the edges of the cored area. ... So how ya gonna tell whether the delamination's due to moisture without using the meter? When you cut it open to re-laminate it, you'll easily be able to tell. The only difference is that if the core is wood, & rotten, then it will need to be replaced. Foam might be OK to re-laminate in place. DSK |

I would rather have a boat that is light & strong & sails well; cored composite laminates are an excellent way to achieve this. All you have to do is learn what's good & what's bad, and look carefully enough to spot the difference. DSK |

Nah, just one side of it. Can be done in small sections if
easier that way. Dave wrote: The one time I tackled such a problem, it was the deck of an Islander with a plywood core. The deck was made up of 3/4" plywood sandwiched between deck and overhead. I wouldn't have wanted to replace less than half of the entire area at once, because the plywood was the major source of support of the deck. Smaller pieces would have weakened it. Also, if there is any water in the ply, it will wick along the grain into other (eventually all) areas. You made the right call. But plywood isn't really a "core" in the structural sense of the term, it's more like the main part... a better term would be fiberglass coated plywood... which can be great stuff, it's just heavy. If the fiberglass skins were strong enough to take the deck loading without buckling, then you could replace the plywood in small sections & not worry about it. The bond between F-glass skins would be the important thing, not the continuity or rigidity of the plywood. I recently worked over some bad spots on the tugboat's deck, and replaced balsa core with filled resin slurry, then put the original deck surface back on, then fiberglassed over it. I don't know what sort of load the deck was designed for, probably doesn't need as much strength as a sailboat deck. But it seems plenty strong, at least as solid as the rest of it.

The work is not that hard if you do it yourself. But if
you have to hire someone--ouch! "Dave" wrote DSK said: Most people don't want to know that badly, so one wonders why they claim to attach so much importance to trapped moisture in their hulls.

The best thing about steel and aluminum, is you don't have
to penetrate the deck to attach something. That keeps the water out of the boat, deck, etc. All you need to worry about are the mast partners and hatches. Given a choice I'd take Aluminum or steel over composite or wood. "Joe" wrote actually, cores can get delaminated from things other than water saturation. DSK Ohhhhhh the nightmares!!!!!!!!!!!!!!!

If you use masts in tabernacles you get the benefit of a fixed/pinned mast structure (more rigid than pure deck stepped) plus no deck penetration. PDW |

You doubt that's a real phone number? Like I said........ WGAF. Unlike your luser friends & yourself, I don't need to hide. 43 06.6 S 147 15.6 E What's the coordinates of your house?
