A few years ago I ended up having to sell my beloved Chris Craft due to termite infestation. I saw a nest of them once, sprayed, threw out the wood piece, etc., and thought I had gotten all of them. But there was a second nest working elsewhere, and when I came back to Florida
in the fall, there was so much damage it was beyond repair. I sold it for 25% of FMV. In conclusion, don't take a chance. I recommend you hire an exterminator and have him check your boat thoroughly and give you a written opinion whether or not you have termites.
