The Alajuela 38 is an American sailboat that was designed by William Atkin as a cruiser and first built in 1977.[1][2][3][4]

The Alajuela 38 is a development of an earlier Atkin design, the Ingrid 38 and the Goucho.[5] Versions of the design were also built by many other builders using an assortment of materials for hull construction, including wood and ferro-cement.[1][6]

Production

The design was built by the Alajuela Yacht Corp in the United States . The company completed about 72 examples of the design between 1977 and 1985, including some boats delivered as bare hulls and kits for owner-completion. Some boats were completed to this design built from wood or using a ferrocement hull. The number reported as completed varies, depending on whether boats sold as bare hulls or kits are counted. The number is thought to be between 70 and 80.[1][3][4][7]

The boat was the company's first design produced and it took founder Mike Riding almost four years to build the hull molds for the start of production.[7]

Design

The Alajuela 38 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cutter rig, a spooned raked stem with a teak bowsprit, a canoe transom, a transom-hung rudder controlled by a tiller, or an optional wheel and a fixed long keel. It displaces 27,000 lb (12,247 kg) and carries 10,000 lb (4,536 kg) of lead ballast.[1][3][4]

The Mark II version has a taller rig of about 7.10 ft (2.16 m), designed by Raymond Richards and has a shorter aluminum bowsprit.[8]

The boat has a draft of 6.00 ft (1.83 m) with the standard keel fitted. The Mark II has a draft of 5.60 ft (1.71 m).[1][4]

The boat is fitted with an inboard diesel engine of 40 hp (30 kW) for docking and maneuvering. The fuel tank holds 65 U.S. gallons (250 L; 54 imp gal) and the fresh water tank has a capacity of 80 U.S. gallons (300 L; 67 imp gal).[1][4]

Sleeping accommodations are provided for five people. These include a "V"-berth in the bow cabin, plus two settee berths and a pilot berth in the main cabin. The galley is U-shaped and located on the starboard side at the foot of the companionway steps. In includes a top-loading icebox and a two-burner propane-fueled stove. There is a navigation station aft. A wet locker is mounted between the aft engine room and the galley. The cabin has a teak and holly sole and is finished in teak wood, with a planked ceiling. The head is located just aft of the bow cabin, on the starboard side. The stern lazarette provides vented storage for propane tanks.[3]

Ventilation is provided by four teak ventilators, plus an optional teak skylight.[3]

For sailing there are three two-speed winches for the halyards and five two-speed winches for the sheets. Tracks are provided for the genoa and the staysail sheets. The mainsheet has a mechanical advantage of 6:1 and employs with a mainsheet traveler. The outhaul is an internally mounted design, with a 2:1 advantage. The side decks are 22 in (56 cm) wide and have a non-skid surface of ground walnut shells. The cockpit coamings are of teak. The boat can be equipped with a spinnaker.[3][9]

The design has a hull speed of 7.65 kn (14.17 km/h).[4]

Operational history

In a 1994 review Richard Sherwood wrote, "this is a passage or cruising boat, not a racer. Long keel gives directional stability, but Alajuela will not turn on a dime. Double-enders offer less area to pooping seas and are intended for cruising. Alajuela has a fast-draining, relatively small cockpit for insurance."[3]
