Chesapeake Tartan 30 Association
About the T30
The Tartan 30 was envisioned and designed to bridge the gap between the Tartan 27 and the Sparkman & Stephens designed Tartan 34. Tartan, keeping with its philosophy of designs that are distinct and unique unto themselves, made sure she is quite different than any of her sisters and offers her owners a clear choice to be considered on the basis of accommodation, hull configuration, and budget. As is the case of all Tartans, the design called for a high performance, off-shore racing cruising boat.
The Builders decision for a fixed keel boat was made after a careful survey of the market and existing models, with an eye towards economy for her owner. Previous experience has contributed heavily to the design and construction of the Tartan 30. Her high aspect rig, weight distribution and divided rudder closely resembles a Tartan 34, adapted from the Sparkman & Stephens designed Twelve Meters. The determination to maintain a skeg mounted rudder reflects the designer and builder's firm belief that ease of steering and handling is significantly improved over a freely suspended rudder. Her above decks teak trim reflects fifteen years of experience with this low maintainance, traditional material first employeed on the Tartan 27.
The Tartan 30 was designed by Sparkman & Stephens and built by Tartan Marine Company between 1970 and 1979. 630 hulls were built during that period in two hull and two interior configurations. The standard rig includes a fin keel with skeg hung rudder that draws 5' while the Competition model has an extra 3 feet of mast, 5'6" of draft and an extra 500 pounds of lead ballast. The interiors came in a center galley and aft galley version. Standard power was the Atomic 4, while some came with a Farymann Diesel.
HULL & DECK
Construction: Fiberglass. High glass ratios of mat and woven roving produce hull surfaces able to withstand the punishment of a head sea without "oil canning." The tasteful employment of liners eliminates condensation as well as providing a maintenance-free interior surface.
Ballast: Lead ballast of 3,700 pounds is cast and fastened with internally cast 1" S.S. bolts, thus concentrating the keel mass as low as possible. The keel's trailing edge is sharp and its bottom shaped to a V to provide lifting action.
Skeg Rudder: Skeg entry for the rudder provides additional lifting surface and eliminates the radical steering behavior of freely suspended blades. The rudder is not entirely dependent on its post, but is attached to the skeg with a bronze shoe. Fairing strips are utilized between skeg and rudder to assure smooth flow. An added benefit to the steering system is the protection for the rudder provided by the skeg.
Deck & cockpit: The functional uncluttered deck and cockpit are designed for comfort and service. Teak toe rails, seat hatches, and grab rails maintain character, while a companionway hatch cover, Dorade vents, and a spray dodger coaming blend into the utility pattem. The cockpit is wide and long with a dual winch island and roller bearing main sheet traveller for sail handling efficiency. A bilge pump is standard and is easily accessible from the cockpit, per U.S.Y.R.U. offshore requirements. Dodger coaming is molded.
Hardware: Three mooring cleats and four chocks make up the necessary dockside equipment and, for offshore work, stainless steel pulpit and lifelines (including stanchion sockets equipped with pad eyes) are provided as standard equipment. The supplied compass mounts in the aft wall of the low-profile house. There are two Dorade vents with 3" PVC cowls.
Forecabin: Two forward berths have 4" foam mattresses and removable nylon fabric covers. There is substantial storage under forward berths; shelves outboard of berths and space for storage or additional water tankage located under-berth abaft chain locker bulkhead.
Head: Marine toilet with holding tank (recirculating system optional). Door can open to close off forward cabin. Lockers and shelves outboard for storage. Stainless steel wash basin. Provision for shower drainage provided in molded sole.
Main cabin: L-shaped settee portside with removable table which can be dropped to form a spacious double berth. Table can also be mounted athwartships for a chart table and stows above the port quarter-berth when not in use. Outboard of dinette/settee is storage with sliding doors and open lockers. Outboard of quarter berth(s) are shelves and storage behind hinged, louvered doors. Forward engine location (improving trim and accessibility) makes available over 50 cu. ft. of additional storage space under the cockpit for stowage of sails, wet weather gear and other equipment.
Galley: The owner may choose from two galley arrangements. Aft-galley version adds settee berth to starboard in main cabin; galley placed close to companionway. Deck-loaded icebox with galley-access to food compartment replaces starboard quarter berth and chart table. Side-galley version includes below-decks icebox and 6' of counter space for meal preparation. Both galleys include stainless steel sink and two bumer recessed alcohol stove.
Finish: Cabin trunk is imported wood with hand-rubbed oil finish. Extensive joinerwork and wood-finish main cabin bulkheads present a traditional atmosphere. Eight fixed ports insure a bright interior. Cabin sole is imported wood, lightly varnished.
MECHANICAL & ELECTRICAL
Power: The 30 Hp. Universal Atomic Four drives a 12 x 8 propeller through a 1" stainless steel shaft. Located off-center to eliminate torque, the engine is set in the forward end of the main cabin to concentrate its weight (together with fuel and water tanks) over the center of ballast and reduce pitching moment. Because the engine is mounted on top of the lead ballast, it is remarkably quiet, free from vibration, and readily accessible. Positive ventilation from engine compartment. Engine instrumentation includes temperature, oil pressure and ammeter gauges, reverse gear and throttle linkage with removable handles at cockpit; blower and engine vent system; muffler with water-lift exhaust exiting portside.
Electrical: 35-Amp alternator charges a heavy-duty 12-volt battery. 12 shipboard lights include 2 domes, 4 swivelbase reading lights, one receptacle/ shaded bulkhead light, running and compass lights. All loom wiring with fused circuits.
