I've had my Castine about 6 weeks now. After paddling a Discovery 174, the Castine is a dream. It handles well, is very stable, and gives me more opportunity (excuses) to go paddling. I'm now in the market for another or the Adventure XL to be able to take along a guest. In my opinion, the Castine is a little easier to handle than the Adventure XL, but I like the slghtly larger cockpit opening of the Adventure. The red with black is beautiful. I get comments from boaters about how nice the Castine looks as it gracefully cuts through the water. The previous comments about handling well in swells and boat wakes goes ditto.
