Operational history

In a 1994 review, Richard Sherwood, described the boat, "This boat is Hobie Alter’s first venture into monohulls and off-shore boats. She is ultra-light-displacement and designed for one-design racing, but will sleep two couples. The 33 tends to sail well heeled. The narrow beam is required so the boat can be trailered. The keel is lifted for trailering, and it is bolted down for sailing."
