Cons - Cost. I can't think of too many other reasons not to. If you day hunt from the boat, you can get to the alpine, but usually only for a couple of hours then you need to go back down. The best hunting is in the mornings and evenings so you miss out on some of the good hunting. During this time of year, most of the hunting is usually done from boats and skiffs less than half a mile from the beach.
Weather is always a factor in late season hunts, but the rewards are outstanding.
November is a great time to catch them in rut - when they will eagerly come to calls. December usually brings enough snow to track them in the lower areas, near the beach.
