Whoch yak for my bro

[Biggameaddict]

I want to got him a yak but i really dont know much about hull types or how they cut through waves and all that. Hes 5'9 or 5'10 and 210 pounds. Were going to be paddling mostly in the harbors and sometimes heading out through the surf or out the wavebreaker. I want to buy him something stable but fast, with good space and thats not hard to paddle. The yak has to be one from malibu kayaks cause im gonna buy it from the sale this saturday. I was looking at the exfactor but its kinda wide making me think its slow? Waiting for your guys inputs. Oh and Storage is not a problem. Thanks.
