Ok...let's see if I can do some definitions according to the way I know them and use them. Remember--this doesn't make it right. It's just the way I do it.
chine: A ridge or crest. In hard chine boats it would be the junction of 2 panels coming together. Soft chine boats don't really have a definitive chine. We just say that to delineate between the curved or flat panel boats.
primary stability: This is how the boat feels while sitting at rest on a horizontal plain. If it's tippy then it has little initial stability. Tippy in one boat and situation may not be tippy in another boat and situation.
Secondary stability: is how the boat resists tipping as you heel over. Contrary to popular belief you really don't want a LOT of secondary stability. It's best to have just a little better secondary than initial stability and the shape of the boat should be such that the transition is easily anticipated.
Coaming: is what you see on sea kayaks and other boats that have the lip incorporated around the cockpit to hold a sprayskirt. The complete assembly is the coaming.
Loft: simply means to transfer the lines of a boat from a small sheet of paper to the actual size on the material (wood) you have chosen to build the boat.
Rub rail: is just what it says--a rail to rub against. Supposedly to keep your boat from being damaged when you slam into the dock. I really don't use rub rails as such. Bigger boats may effectively use rub rails, but a kayak really shouldn't need them. That's just my opinion.
Strake: is a single plank that reaches from the stern to the bow. What I call panels on the panel boats--like the pirogue, 4 panels, 5 panels, etc.. I started using that term some years ago after I bought an old (modern at that time) dos program for plywood boat design. Plyboats is the name and it is still sold today. Anyway--this guy used "strake" for the panels. I looked it up, liked it, and try to use it now.
Heel: is to lean your boat, regardless of how much. You can lean 10, 20, or more degrees until you flat tip over--then if you're pogo in his rolling boats you can roll back up. While paddling you can heel a boat to counter wind, waves, current, etc.
Pirogue: is just a 3 panel boat. The traditional pirogue used in the swamp in Lousiana is what most of us think about but these little boats can be made to do so much for so little. It's really difficult to compare a 3 panel boat with a canoe. Each has good points and bad points. While a pirogue is the most boat for the least money and work--and canoe can be the best, single, general purpose boat you can have. All this is relative to design.
Hot air perow: Haaa...well, you know Ron. He's just a good old central Texas boy. He can blow a lot of hot air. I think this was just one of his back country euphemisms for something or the other. I just love some of the things he comes up with. I try to remember them.
Beam: Yes...the widest part of the boat measured at the sheer (top--at the widest point).
Brazos River Fishing Boat: Ok...I believe I'm starting a new term for an entire "style" of boat. This is more of a way the boat is rigged out with the open cockpit, hatches, seats, etc.. This style can be applied to 3, 5, possibly 6, definately 7 panel boats. At present I do this style only with the 3 and 5 panel design. There is a 7 panel in the future.
