My Arrow 14 has a double layer of Dacron. I only doubled up to third strut from the gunwale (I think; I’d have to look). I followed Platt’s recommendation, which was to shrink the first layer fairly tight. Do that first, THEN add the Heat’n Bond and the second layer. I think the order was: 1) shrink the first layer; 2) iron on the Heat’n Bond sheets; 3) Apply the second layer, melting into the Heat’n Bond and shrinking at the same time. But you don’t shrink the outer layer as much. Then trim.
Don’t forget to lay the second layer at about a 45-degree angle to the first layer. The idea is that ripping occurs along the grain, and with the second layer, there is no longer any grain. Then, any holes won’t rip wider.
I tightened the Kevlar after all this.
I built the boat in 2002 and it’s still running. I launch it over rocks on the coast of Maine and never had a rip. I used varnish for the Dacron and gave it an extra coat a couple of years ago.
Hope this helps. Have fun!
