I have used smaller kayaks that I rented before. I am 6'5" so comfort has always been an issue for me mainly in the bulkhead, except for this Dagger. I have plenty of room to spare in this even after adding some foam. I try now to go out every weekend and get a little paddle time in on a local river. I feel very confident in this boat safety-wise and comfort-wise. Not having a skeg is an issue on calm waters but that is not what I got this boat for.
This is a well made boat with almost infinite outfitting adjustments. It is the most adjustable boat I have seen, with very comfortable footrest, thigh pads, and seating. There is even enough front to back adjustment on the seat to make a significant difference in the trim of the boat. Spend the time up front and be picky about every aspect of the setup and you will be rewarded with as comfortable a ride as you can find anywhere. I set mine up to my preferences with standard adjustments without having to use any of the generous supply of padding and shims that come with the boat.
If you're looking for a solid boat to do big water down river, this is it. You're not going to do a lot of playboating, but surfing and hole shots are solid. Combine that with its stability and ease of rolling, along with its speed and turning ability and I got pretty much what I wanted. I can cover a lot of rough water, carry some extra gear, stay comfortable, and do some surfing and other fun things while I'm at it. Not a bad deal.
