I purchased the Stratus 18 for one reason- Speed. Although its a very fast and efficient boat, I was surprised how stable it is for a long, narrow kayak. I've had it out in some pretty decent waves on the Great Lakes and there were no worries at all.
I wasn't planning on using it for week long trips but the gear I can get in it is unbelievable. It makes paddling through the rivers of Northern Ontario a complete delight. It even handles small sets of rapids with ease although that's not what its made for.
As the owner of 4 previous kayaks, the Stratus 18 is by far the best boat I've paddled so far. The only people that don't enjoy it are my paddling buddies who now have to paddle harder to keep up!
