A couple of tips for your build. If you are looking to save money try to buy some of your materials in bulk. Epoxy is very expensive to ship so you'll want to order it all at once for both boats. US composites has good epoxy but it is expensive, fasco epoxy (103LVX) is good and cheaper (they shorted me on some hardener
so I won't order from them again), MaxBond is the cheapest I could find but too viscous for a good wet out unless thinned with 5-10% acetone (it works fine once it is thinned). If you want to save money on cloth you can buy it by the 50 yard roll which works well if you can get a couple friends together to split the cost (drops the cost to around $2.50/yd for the whole roll and will build about 4-5 boats).
My first hybrid NL I built cost me $350 (I sold it and built a longer version to hold me and the dog). For the last two boats I built I was able to get the cost down to around $500 for the pair by buying in bulk and shopping around. Plus I still have 30 yards of cloth on my roll, 1/2 gallon of epoxy, and some fiberglass tape and other supplies in case I have to do repairs or decide to make another boat.
