Though it’s a bit longer than your previous 16ft boat and weighs from 55 lbs. Sprayskirt is optional and ridiculously expensive. But you will get A LOT of cockpit - I think 50" from the rear-most position of seat to the fore point.
paddling calm waters
does it need to be a “sea kayak”? Unruddered CD Kestrel 120X is 42lbs w. 43" coaming.
