My Two Cents
Renounced racing in 1996 and bought a 376.Have been cajoled into racing three times since then.Results are one first, one second and one third.We are always testing ourselves against other boats of similar size and mostly come out on tops except when against the full race boats who do an horizon job on us.I believe the 376 is quick unless it has a dirty bottom and loaded with excess gear.Tacking downwind is the way to go on all boats which do not carry a spinnaker up until the true wind reaches about 20 knots when we run dead before and furl the jib. Then we fit a preventer - and so does everyone else.The 376 is no different from "conventionally" rigged boats in this respect. it also benefits from the enormous (free) roach on the mainsail.
