I'm looking at buying a kayak this spring and would like some advice on which kayak to buy. My skill level is beginner to novice. The kayak will mainly be used on flat rivers and lakes for day trips, but a couple of overnights are possible. I would like to have a dry storage area. The problem I'm running into is my size. I'm currently 6'2", and 275 pounds, so I need a kayak that has a relatively large weight capacity. Also, preferably an easy in/out since I just had a knee replacement about 6 months ago. I know it's a large task, but some advise would be appreciated. I've looked at the Dirigo 120, but saw the max weight was 325-350. Is that good enough?
