Design and Construction
The Bahama 30 measures 29.92 feet LOA and 24.58 feet LWL. It displaces 8,230 pounds and carries 3,130 pounds of lead ballast.
Finch specified a one-piece, solid-fiberglass hull with a fully enclosed lead keel. Notably, there are no keel bolts to monitor, eliminating one traditional potential failure point from the maintenance list. The hull is of one-piece construction with a fully enclosed lead keel.
The deck and cabin trunk are plywood-cored to shed weight. At the hull-to-deck joint, the deck is bedded in sealing compound on an inward-turned hull flange. A slotted aluminum toe rail secures the joint with through-bolts spaced every four inches.
The balanced spade rudder is foam-filled and turns on a stainless-steel post accessible through the stern locker. A keel sump about a foot wide and a foot deep runs from the mast step to the engine bay.
Like other Islander boats of the era, the Bahama 30 has an interior finished in off-white vinyl over open-cell foam glued directly to the bare fiberglass.
Rig and Handling
The single-spreader aluminum mast is deck-stepped. The majority rest in a simple socket supported by the forward bulkhead and a compression post rather than by a structural tie to the keel.
The sail plan totals 449 square feet beneath a 43.5-foot mast. The rig dimensions include an I of 40 feet and a J of 12.75 feet.
Under sail, the fin keel and spade rudder make the Bahama 30 responsive, but this isn’t a hands-off boat. She is very sensitive to rudder input and requires an attentive helm. Practical Sailor placed her stiffness between two contemporaries: she was not quite as stiff as the beamier Catalina 30, yet remained more composed when heeled than the lighter Ranger 29.
Accommodations
Immediately abaft the companionway, a U-shaped galley sits to port. Its counter leads to a large icebox. To starboard is a double-wide quarterberth more than seven feet long.
The main cabin has opposing settees. The starboard settee measures 6 feet 6 inches and has tilted seat backs. A heavy MDF drop-leaf table folds down from the bulkhead.
The head spans the hull, with the toilet and a locker to port and a small vanity to starboard. Forward, the V-berth is just over six feet long, roomy, and king-size across the shoulders. Headroom is 6.25 feet.
Machinery and Tankage
The original Volvo Penta MD7A diesel produces 13 horsepower and draws from a 20-gallon fuel tank. Despite the boat’s modest waterline length, the engine could drive her to hull speed. Freshwater capacity is 25 gallons.
The Bahama 30’s simple, liner-free structure provides a straightforward basis for incremental refits. However, the vinyl-over-foam interior finish and MDF table are period construction choices that age on their own terms.
Known Issues
Early-production hulls were fraught with osmotic blisters below the waterline, a documented weakness during the first years of production.
Mast compression presents a separate structural concern after more than four decades. The compression post lands on the cabin sole, which rests on a plywood sub-frame glassed into the hull rather than bearing directly on the keel. Buyers and owners should treat both blistering and compression-related sag as inspection priorities, not cosmetic afterthoughts.
The Verdict
The Bahama 30 is a thoughtfully engineered small cruiser-racer. Its boltless enclosed keel and cored deck reflect Finch and Islander’s efforts to solve practical ownership problems in 1973. The boat rewards an engaged helm and offers more accommodation than its length might suggest. However, early hulls require careful blister scrutiny, and every example deserves a compression-post inspection.
Pros
- Enclosed lead keel with no keel bolts to maintain
- Roomy V-berth and seven-foot quarterberth in a 30-foot hull
- Responsive fin-keel and spade-rudder handling for club racing
Cons
- Early hulls are prone to osmotic blisters below the waterline
- Mast compression can cause the cabin sole to sag because the supporting sub-frame doesn’t bear on the keel
- Sensitive helm is poorly suited to careless solo sailing
