I'm interested in this thread as I am thinking about purchasing a Delta 17 in the near future, and it is made with the thermoformed plastic.
Thermoformed would be at the bottom of the heap. Thermo is also pretty restrictive as far as hull shapes go.
Why is thermoformed plastic at the bottom? I've heard that it performs more like glass than rotomolded plastic yet is almost as strong as RM.
I've also read that the finish they put on the Delta's make them more resistant to UV rays than RM or glass boats.
Now I don't work for Delta and I don't own one (yet) but I must admit I'm really close to buying one. Would a glass boat really outperform a plastic boat so much that I would notice? I'm a newbie to the sport and am looking for something that is durable, affordable, and performs well.
