Weird core repair technique

A friend of mine has a damp balsa core on his J raceboat, though no delamination was found on the boat on survey, and a core sample showed intact though damp core.

He decided to pilot this technique he found online in a section of his hull over the winter:

Balsa Core Problems


This friend drilled a grid of holes on one section of his hull as detailed in this article right before offseason. He reports moisture readings near 30 throughout hull but after the winter dry out the moisture readings were down to 10 in that area, and 30 everywhere else.

What does everyone else think? I am curious about the unconventional thinking in the article. I wonder if it works for decks where people tend to more commonly have moisture. My boat's dry, but I hear of this kind of issue commonly.

Re: Weird core repair technique

If the core is not rotted then no repair needs to be made, just let it dry. If the core is rotten this technique doesn't work. It traps all the rotten wood pulp inside the laminates and prevents anything good from happening. Injecting goo at best disguises the problem.

As a cheap repair for a disposable boat that you just want to get another year out of it will work, but it makes it even more difficult to fix correctly down the road.

Re: Weird core repair technique

Ok- that's what I thought as well. Drying it out is the solution. I was hoping to dissuade the friend from injecting goo...
