OK you guys, I need to set the record straight. There is only one REAL Carolina and it is in Chapel Hill, not Columbia

BTW, my daughter is just finishing her second year at Georgia.
On the subject of stitch and glue, I agree, it is a great way to build your first or your 100th boat. Being at Clemson, you have Lake Hartwell and a few rivers very close. You could build a lot of different stitch n glue boats. I built a 16.5ft stitch n glue kayak in about 4-months and I worked on it almost every night until 2am. It can be done quicker, but appearance may suffer. It's length required joining long sections of wood that had to be within certain tolerances and then the epoxy had to set. Things like that will take you an hour or two to do but they then have to set overnight before you can touch them again. Fairing takes a lot of time and all the sanding after you add the glass seem to take forever. In other words: many of the steps are easy and done quickly, but things like letting epoxy set and hours and hours of sanding will make the calendar pages turn.
As far as costs go, it will depend on your skills and the tools you have access to. Things like palm sanders, random orbital sanders, circular saws, table saws, jig saws are not a requirement, but very helpful. Of course basic hand tools have been used for as long as there have been boats. Marine grade plywood (Okoume is great for stitch and glue), epoxy, varnish...those things add up quickly and not always available at just any lumber store. The one thing that seems the most ridiculously priced to me is epoxy. You can find it online for better prices than a place like West Marine, but the shipping and then the hazardous materials fees add up. Marine varnish is not cheap either, but a little bit goes a long way. A good respirator (not a dust mask) and safety glasses are an absolute must. A lot of this stuff has harmful vapors and the dust from sanding epoxy is really harmful.
If you are at Clemson, you must have some good science/engineering skills already, so I'm sure you can do it. But I'm not so sure you can do it over the summer.
