1978 34' Tartan 34c Sparkman and Stephens

Expired
$19,500 USD

Seller's Description

Moored in East Greenwich, Rhode Island. Here is your opportunity to own a classic 1978 Tartan 34c Hull number 506. STELLAR is a US coastguard documented sailing vessel, designed by Sparkman and Stephens and produced by one of the last remaining operating builders of fine sailboats in the US. The thick fiberglass hull sports a centerboard with a 3.92 foot draft in the up position allowing one to explore gunkholes other deeper draft boats cannot access. By lowering the board to 8.33 feet, she powers to windward with her performance rig. The skeg hung rudder provides performance, protection and peace of mind. She motors well in forward and reverse with the Atomic 4 gasoline engine (30 hp) lovingly maintained by her owners. This Moonbeam cream Awlgrip painted masthead sloop sports a Doyle 135% Genoa and North Mainsail both professionally inspected, washed and stored each winter with Dolye Sail Loft (East Greenwich, RI).The 2-reef mainsail is protected from the damaging UV rays with an easy to use custom seafoam green sail cover with jacklines. Coordinated dodger and Bimini provide cover for skipper and crew. The UV protected Genoa is mounted on a Harkin (2017) roller-furler allowing for easy set and retrieval from the cockpit. This powerful rig drives her to windward and all points of sail with surprising performance. A colorful spinnaker rounds out her compliment of sails. This symmetrical spinnaker using the provided ATN Tacker and snubbing sock is fantastic for dead downwind to beam reach sailing in light winds. The Tacker allows for the spinnaker to be tacked from the cockpit once deployed. The stainless-steel standing rigging has been is inspected and tuned yearly by New England Yacht Rigging. The boat can be easily singlehanded as she has stout safety stanchions and stainless-steel lines with wide decks. The Raymarine TillerPilot ST2000 seamlessly drives the boat along while relaxing or making sail changes. For navigation, a 2017 Garmin GPSmap 7610xsv 10 bulkhead mounted chartplotter is viewable from anywhere in the expansive cockpit.

Equipment: A raymarine ST-60 wind instrument provides windspeed and direction. The 25-pound Mantus anchor grabs and is easily retrieved due to the renowned modern design and is stored on a custom bow roller installed in 2018. The chain-rode combo stores in the bow locker accessed through the v-berth for inspection. A Danforth anchor rests in the cockpit locker and serves as a lunch hook or backup. Another useful safety feature is the Standard Horizon Matrix AIS GX2200 - 25watt marine radio with built in AIS receiver. The radio allows for direct digital calling of AIS contacts as well as distress notification due to the built in GPS receiver. An electronic bilge pump ensures the bilge is dry. Another high capacity bilge pump serviced in 2020 can be operated from the cockpit in the event of an emergency. Blue Seas M2 Battery Monitor and BlueSeas ACR automated charge controller were professionally installed by King Payne of EGYC in 2019. Two 90 amphour flooded lead acid batteries are new 2019. All through-hulls have been inspected and replaced where necessary to meet safety requirements. The Lifesling system, fenders and lines to enable easy and secure docking are included. Teak rub-rail, coaming and cockpit grate woodwork accentuates this classic yacht. The 6ft doghouse provides headroom. The galley is found at the bottom of the oiled companionway ladder & ice box is assessable from the cockpit and galley. A Origo double-burner alcohol stove is great for prepping meals and hot drinks. Ample food storage space to accommodate a week long cruise can be found in the galley. Fresh water from a 36 gallon tank is supplied via a hand pump to the galley sink. Hot and cold pressurized water is available at the galley or head sink. Hot water is generated by the engine or via 110v AC when at the dock or on the hard. The shore power AC allows for the battery charging and use of standard appliances. The boat includes berths for 6 close friends or family but is perfect for a cruising couple. The cabin cushions are classic Tartan Royal Stewart fabric and are spotless. They are stored in a controlled environment off season. 3 opening ports provide excellent ventilation throughout the summer. The v-berth sleeps two while the salon converts to a comfortable berth for two. By lowering the salon table, a commodious dining/work space is appreciated. The private manual head performs well with a 12 gallon holding tank. Alternatively, waste may be pumped overboard if outside permissible.

Calculations

Hull Speed
9.7 kn
Classic: 7.03 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

9.74 knots
Classic formula: 7.03 knots
Sail Area/Displacement
23.2
>20: high performance

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
23.23
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
42.6
>40: stiffer, more powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

42.57
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
121.1
100-200: light

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
121.14
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
18.4
<20: lightweight racing boat

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
18.38
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.9
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.85
<2: better suited for ocean passages
>2: better suited for coastal cruising
