Seller's Description

(See the listing on Boats.com for 40 more pictures and a video made in 2012, before Serenity became what she is today.)

Tartan 3700 is a great performance cruiser. Cruising World chose the Tartan 3700 as its “Boat of the Year.” Sail magazine named the Tartan 3700 a “Best Boat.”

She is a classic. Her cabin is cherry paneled with a teak and holly sole, providing a warm, inviting feel. The topsides, cabin roof, deck and cockpit have appealing classic lines. Take the stern for example. Its swim platform is hidden behind a drop-down transom. The 3700 looks like a sailboat ought to look.

Serenity is a Tartan 3700 on steroids.

Several enhancements set Serenity above every other 3700. First, its diesel generator enables you to live comfortably offshore indefinitely. Ice wont melt. Enjoy as much heat or air conditioning as you want. The generator makes cruising as comfortable as your life at home.

Second, deploying Serenity’s full enclosure turns your cockpit into a solarium. It captures solar heat even on overcast days. It also blocks wind and rain, so you can be warm and dry when the weather turns nasty.

Third, she is rigged for serious sailing. The 3700 has a PHRF rating of 113. Serenity improves on that with its asymmetrical spinnaker, top-down furler, cunningham, and adjustable genoa cars. Shes a joy to sail.

The generator, enclosure and asymmetrical spinnaker put Serenity above every other 3700 in the market, but theres more:

Xantrax inverter/charger

Quicksilver dinghy, 2-stroke Mercury motor and Garhauer motor lift.

Strong track system.

Mast conduit.

Impeller access port and SpeedSeal cover plate.

Racor fuel filter.

Wifi signal booster

Cut-out switch for cockpit speakers.

Cable/antenna nipple at the stern.

Other Tartan 3700s may have some of Serenity’s enhancements but none has them all.

Equipment: Fisher-Panda diesel Generator (39 hours) Full cockpit enclosure and hard dodger. Raymarine navigation instruments. Raymarine chart plotter. Standard Horizon VHF. Asymmetrical spinnaker on Selden top-down fuller. Adjustable genoa cars. Harken genoa curler Quicksilver dinghy, Mercury 5hp 2-stroke motor and Garhauer motor lift. Racor pressure monitoring fuel filter. MarineAir heater and air conditioner. Adler Barber refrigerator and ice maker. WiFi signal booster. Panasonic radio with iPod connection and cut-out switch for cockpit speakers. Microwave oven. LG television set. Custom v-berth innerspring mattres and bedding. Impeller access port and SpeedSeal cover plate.

Calculations

Hull Speed
8.8 kn
Classic: 7.58 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

8.76 knots
Classic formula: 7.58 knots
Sail Area/Displacement
17.8
16-20: good 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.
17.8
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
37.6
<40: less stiff, less 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

37.62
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
217.6
200-275: moderate

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
217.55
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
24.9
20-30: coastal cruiser

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
24.93
<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
2.0
>2.0: better suited for coastal cruising

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
2.01
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Alternative draft:
Keel/CB verson - BU: 4.0’ BD: 8.0’.
Shoal draft version (‘beaver tail’): 5.0’.
