1708 mat for stringers

[tartuffe]

The U.S. Composites is non blushing if you use their slowest hardener. The middle and quick cure are both blushing.

I'm up to 17 gallons used at this point. The transom used up a good portion. I left about a 2" gap between the wood core and gunnels/hull all the way around the transom to be sure to get it packed full of PB. In hindsight I could have gotten by with a thumbs width. That would have resulted in 2.7 gallons less epoxy. I also used a large amount on the stringers. I bedded those in PB rather than use the foam. That would have saved another 1.25 gallons. Same with the front bulkhead. Also used around 1 gallon used on fairing compound. If you don't need any fairing then you can eliminate that as well.

Oh yeah, I wasted about a gallon when I got ahead of myself and it kicked off so all told I'm up to around 5 gallons of over expense, or education whichever term you prefer.

At this point for new transom, stringers, bulkheads, reinforcement, and floors for storage compartments I'm up to 5 sheets of 3/4 marine grade fir. 21 gallons of epoxy and 50 yards of 17 oz mat at 50" width. Around 2.5 gallons of 1/4 chopped strand, 4 gallons of cabosil, and 1 BILLION 4.5" 24 grit sanding disks. My boat was toast.

Do not add up the costs. Just start it and build as you can afford. As you probably know, working on the boat is half the fun!
