Tell us about yourself!
Had my doubts but yea, boat. Perhaps not very seaworthy though.
Nibblers work best in sheet metal but I have used them in soft thin plastic. Sadly, they do tend to cause cracking and shatter in hard or brittle plastics, so like you I use my little dremel, but usually with the little saw blades instead of cutoff wheels, The saw blades are a bit scary. I always feel like I might take finger off if it were to bind & jump so best to NOT do what I do & wear gloves.
