Design and Construction
Bristol Yachts built the 45.5 as a heavy, solidly constructed monohull carrying 34,660 pounds of displacement on a 37-foot-3-inch waterline, with a 13-foot-2-inch beam and a lead ballast of 15,000 pounds. The keel-centerboard arrangement is a Hood signature, giving the hull a minimum draft of just under five feet with the board up and a deep 11-foot draft with it lowered, so the boat can poke into shallow anchorages without giving up windward ability. The same hull mold later underpinned the Bristol 47.7, a longer-sterned, traditional-transom evolution that succeeded the 45.5 around 1989–1990. Within the second-generation Bristol line, the 45.5 is regarded as blending rugged construction, a comfortable motion at sea, and the kind of capable offshore performance that defines a serious cruiser rather than a coastal weekender.
Rig and Handling
The 45.5 was offered as a masthead sloop or with an optional ketch rig, and the sloop's sail plan centers on a 399-square-foot mainsail paired with a 115-percent jib of roughly 486 square feet and a 150-percent genoa stretching to about 752 square feet. The I dimension runs 54 feet with a J of 18.5 feet, and the P and E of the main are 47.5 and 16.5 feet respectively. Reaching sails include an asymmetrical spinnaker of 1,241 square feet and a larger symmetric spinnaker near 1,535 square feet, while a 174-square-foot storm jib rounds out the heavy-weather inventory. Period assessments credit the design with excellent handling in heavy weather, a quality that, together with the comfortable motion already noted, explains much of its reputation among long-distance cruisers.
Accommodations
The model was produced in both center-cockpit and aft-cockpit forms, but the center-cockpit version is the more common of the two and is valued for the privacy and the easier motion it affords underway. That layout places the helm station amidships, separating the owner's statery forward from guest quarters aft, a configuration that suits extended liveaboard use and offshore passages where sleep quality matters. The classic, almost luxurious interior appeal noted by reviewers sits well with the boat's heavy build and bluewater intent, marking it as a cruiser's cruiser rather than a charter-friendly open plan.
The Verdict
The Bristol 45.5 is a thoughtfully executed Hood design that pairs a versatile centerboard hull with a heavily built, seakindly platform and a sail plan scaled for ocean work. Its center-cockpit arrangement and classic finish give it enduring appeal for serious cruisers, and the lineage to the later 47.7 confirms its mold was a strong foundation rather than a dead end.
Pros
- Hood-designed keel-centerboard hull with shallow and deep draft modes
- Heavy, solid construction with 15,000 lb lead ballast in 34,660 lb displacement
- Excellent heavy-weather handling and comfortable motion per period reviews
- Center-cockpit layout favored for privacy and sea-kindly motion
- Sloop or optional ketch rig with full offshore sail inventory
Cons
- Production ended around 1989–1990, limiting newer examples
- Center-cockpit variant more common, aft-cockpit harder to source
