Tank capacities — where the figures come from
-
Fuel 20 gal
“17-gal (77-liter) aluminum fuel tank” — review, practical-sailor.com · “20 U.S. gallons (76 L; 17 imp gal)” — search excerpt, en.wikipedia.orgPractical Sailor's 17 gal matches its own 77 L, so it's in imperial gallons; 77 L is 20 US gal, which agrees with our earlier figure. No builder document was found online.
-
Water 25 gal
“25 gallon (95 liter) plastic water tank” — review, practical-sailor.com · “25 U.S. gallons (95 L; 21 imp gal)” — search excerpt, en.wikipedia.orgPractical Sailor notes early boats filled from below; later ones had a deck fill.
-
Holding 15 gal
“a 15 gallon (56 liter) holding tank” — review, practical-sailor.comFrom one magazine source, Practical Sailor: 56 L, which is 15 US gal.
-
Water heater unknown
“Open storage became cabinets and the hand pump for water at the sink became a hot and cold pressure system.” — review, practical-sailor.comPractical Sailor says early boats had hand pumps only and later model years came from the factory with hot and cold pressure water; it does not say whether that was standard or optional, and gives no heater size or years.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster unknown
No source mentions a thruster on the Bahama 30.
-
Stern thruster not fitted
Nothing was found either way; our earlier figure of none appears to be an assumption.
-
Steering pedestal cable
“The wheel pedestal seriously infringes on usable space ... in later models purchasers could select a choice pedestal opt” — review, practical-sailor.comPractical Sailor (an owner-written used-boat review) describes a wheel pedestal driving a quadrant in the stern locker and suspects a tiller was the original design intent; later buyers chose between pedestal packages. The pedestal maker isn't named, and the cable type is inferred from the quadrant layout in this one source.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Solid glass hull with lead ballast fully encapsulated in the keel (no keel bolts); plywood-cored deck and cabin trunk. Deck-stepped mast over a compression post. Sailboatdata says it shares its hull with the Islander 30 MkII; Practical Sailor says the two differ in coachroof, interior and rudder position, and that together over 500 were built through 1985. Shoal keel 4.0 ft. Aluminum fuel tank under the cockpit sole. Kerosene stove was original.

Known problems for this model
-
Leaky hull-deck joint deck
The deck sits on sealant over an inward hull flange, through-bolted with the aluminum toerail; it tends to weep and needs periodic tightening of the nuts behind the headliner.practical-sailor.com
-
Cabin window leaks rotting plywood core deck
The big fixed acrylic cabin windows flex and break their seal, letting water into the plywood-cored cabin trunk hidden behind the vinyl headliner.practical-sailor.com
-
Chainplate deck penetrations rigging
Shroud tangs pass through the deck to the main and forward bulkheads; the deck plates need regular recaulking to keep water out of the plywood deck core.practical-sailor.com
-
Osmotic blistering on early hulls hull
Early production hulls were prone to heavy blistering, sometimes hidden under a later gelcoat layer; survey the bottom carefully.practical-sailor.com
-
Rudder tube with no bearing steering
The foam-filled spade rudder's stainless post runs in a plain fiberglass tube; early boats have no stuffing box, later ones added one.practical-sailor.com

Original engines at end of life engine
Original Atomic 4s and Volvo MD7As are well past normal service life, and repower cost can approach the boat's value.practical-sailor.com
-
Boom-bolted mainsheet blocks rigging
With the forward traveler option the mainsheet blocks were simply bolted to the boom and can pull out in a hard gybe.practical-sailor.com
