My first sea kayak was the Cayuga 146. Love, love, love this sea kayak. Plenty of storage and it handles everything that is thrown at it. Also, for a 14 1/2 foot boat, it is fast. Down side is the seating;not the best seat for re-entry.
Two years ago, I bought a used glass Betsie Bay Manitou. 18 foot, fast, handles everythig quite well and fantastic for rolling. Down side is the storage. This boast is 22", so the storage hatches are small. Luckly I travel with my bud who has a Current Design with more than enough storage. The plus with the storage is that it is 99% water tight.
