The Bahama 30 is an American sailboat that was designed by Robert Finch as a cruiser and first built in 1973.

The Bahama 30 shares the same hull design as the Islander 30 Mk II.

The design was built by Islander Yachts in the United States, from 1973 to 1986, but it is now out of production.

The Bahama 30 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel. It displaces 8,230 lb (3,733 kg) and carries 3,130 lb (1,420 kg) of lead ballast.

The boat has a draft of 5.00 ft (1.52 m) with the standard keel fitted. There was also an optional shoal draft keel.

The boat is fitted with a Swedish Volvo MD7A diesel engine of 13 hp (10 kW). The fuel tank holds 20 U.S. gallons (76 L; 17 imp gal) and the fresh water tank has a capacity of 25 U.S. gallons (95 L; 21 imp gal).

The design's galley is on the port side, at the foot of the companionway steps. It has a two-burner alcohol-fueled stove and an insulted icebox, which can also be accessed from the cockpit. The head is across the beam and just aft of the bow "V"-berth. It includes a shower. There is a double main cabin berth from the converted settee and a starboard quarter berth. The interior trim is teak, while the cabin sole is teak and holly. The cabin headliner is vinyl. There is a forward hanging locker and a forepeak storage compartment. Ventilation is provided by four opening ports and a forward translucent hatch.

There are genoa tracks, main and jib winches, slab reefing and internal halyards along with a topping lift.
