Paul, What did you do about the thru-bolt holes on the inside of your cabin? Did you fill or cover those in any way? Are the leftover holes really ugly?
I had *thought* that the thru-bolted windows on my LF38 were a feature / desirable attribute (for offshore strength) and that C&C had just done the adhered windows on the more racery boats (37+) because they don't have the port strength concern. But reading Don Casey's article you linked, it sounds like the thru-bolts may actually be a liability, because they cause cracking when the plastic expands or the boat flexes. If Don Casey thinks VHB is strong enough for offshore then I can probably trust him since he's usually conservative in terms of safety factors. I'll probably do this project in the next year. I was planning to keep the thru-bolts but if they're not necessary that will make my wife happy because she hates the look inside (ours don't even have cap nuts, just nylocks). -Patrick 1984 C&C LF38 Seattle, WA On Tue, May 23, 2017 at 5:27 AM, <cnc-list-requ...@cnc-list.com> wrote: > On 2017-04-25 2:18 PM, Dreuge via CnC-List wrote: > > Hi Mark, > > I installed new ports via VHB tape and Dow 795 using Krylon Fusion to make > a bonding mask.
