You'll find this problems in places where deck hardware and fittings are through-bolted (or if there's a crack in the surface). It's caused by water infiltrating the balsa core layer where the seal was inadequate or the fitting loosened up and caused a breach. You can tap around suspected areas with the handle of a screw driver and hear the difference between a dry area and one that's soaked in water. Thud vs tap I guess you'd call it. Someone may correct me, but I believe the cored areas are limited to horizontal surfaces--deck and house top only maybe? t On Thu, Jun 5, 2008 at 10:59 AM, Andrei Caldararu <andreic@math.wisc.edu> wrote:
Dear all,
as I explained in my earlier messages, I am looking at buying an older, 1975 M-17. Some people here have expressed concern about deck core rot. How does one tell? What does it look like? Where to look for it? Since now I have a Compac 16, I never had to contend with the issue.
Thanks,
Andrei.
