If you are sailing for two to three days then you are within a fairly accurate weather forecast. As such, IMO, a lightweight boat is fine.

We've sailed lots of different Beneteaus (First and Oceanis), Jenneaus and Gibseas and, frankly, didn't like them. All flat bottom fin keel boats slam going upwind, they all broach and they are all skittish.

Some get into deep trouble. For example some good friends of ours were delivering a Jeanneau 42 from the BVIs to Antigua in a near gale and it was slamming big time. It sank NW of Antigua in short order and the sinking was put down to hull failure or a water tank in the bows breaking free and puncturing the hull..

However most owners of such boats (with obvious exceptions on this forum) don't go out in such conditions, so going light shouldn't be a problem.
