The answer somewhat varies with the model. I have quite a bit of contact with the Beneteau First 345, First 38s5 and First 40.7. I have been quite impressed with all three in terms of sailing ability and boat for the dollar. The 40.7 seems to be an amazingly sturdy boat with exemplary sailing manners. The 40.7 that I have been racing on just won the IMS Mid- Atlantics (as a nearly 4 year old pretty much box stock boat with something on the order of 10,000 ofshore miles) beating some very well sailed and prepared boats.
The other two also seem quite sturdy as well, although some of thier original details have not held up well. Beneteau uses
Lewmar hatches and the plexiglas on the mid-80''s and early 90''s
hatches does not seem to hold up very well on the
Lewmars. I found the 38s5 an easy boat to short-hand or single-hand although the versions with the traveller in the cockpit would be easier to handle than the ones with the traveller on the cabin top.
