The only one that will complain is the next owner. Don't waste time fixing them of you plan to grind a little off and fill them in a week. They will indeed return. To fix them properly, the area that is being repaired needs to be dry to 3% or less. This can take months just sitting in the yard or less if the boat can be put in a climate controlled environment. Wait until you won't be using the boat for a while and fix them then. In the mean time, deal with other stuff that will affect your sailing pleasure. Chuck |
So not true. Blisters are a sign of a saturated laminate. A saturated laminate leads to hydrolysis and
delamination. I've seen it many times, it's a known fact. A boat can certainly delam for other reasons as well, but the relation is undeniable. I have professionally dried countless hulls, and I've never ever seen a reading of 3%, not even in a brand
new boat that hasn't been in the
water yet. Most barrier coat manufacterers want you to reach 10% relative or less to get the warranty. I have never seen a wet boat reach 10% by any method other than Hotvac, air drying will usually only get you to 12-13% at best, no matter how long you dry it, unless perhaps you are in a desert. This means if you want the warranty, you need to use a Hotvac or talk a factory rep into giving you the warranty at a higher reading. People here have done that before, someone on the forum got a warranty at 19% by being persistent!
