1980 Watkins 27 coastal cruiser

Expired
$15,900 USD

Seller's Description

Watkins sailboats were built in Florida from ‘73 to ‘89 and this model 27 was originally designed and built starting in 1977 by the Naval Architect Walter Scott. The design was a success and so over 500 were built.

The current owner has totally refinished the boat inside and out from the fin keel to the masthead. The water and fuel tanks were replaced with new as was all interior plywood and installed new white oak.

The cockpit is fitted with all new electronics and the mast was also totally reworked with all new fittings.

There’s a new compost style head, shower, refrigerator/freezer, and an alcohol stove in the galley. No AC but lots of portholes to let the breeze in and there is a cabin heater.

The owners have put a lot of hard work and $$ into this boat and though they would like to keep her, the plan has changed to hit the road in an RV.

Dinghy included: Inflatable with no engine

Calculations

Hull Speed
7.2 kn
Classic: 6.52 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

7.19 knots
Classic formula: 6.52 knots
Sail Area/Displacement
14.7
<16: under powered

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.
14.74
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
46.7
>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

46.68
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
253.0
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
252.96
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
21.7
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
21.72
<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
2.04
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

A pilot house version was available, but less than 10 were built. A keel/centerboard version exists but is also rare.
Draft BU: 2.75’
Draft BD: 6.50’
