No cool open bow classic Glastrons? Bite your tongue! The CVZ-18 is convertible so to speak, but the front is a bit cramped for adults. Overall, the classic Glastron lineup passenger compartment really didn't change that much between 16's, 18's, and 20's. The 23's have a cuddy which would easily fit a large cooler and gear and free up the passenger area. I've had four adults and cooler in a 16, an 18, and in 20's. Keep an eye out for the GCOTD section that Gregg updates regularly. Plenty out there, but to start, what is your price point, and are you wanting a water ready or project craft?
