Equipment: ACCOMODATIONS RESOLUTE - sleeps seven which includes the dinette/berth, midship cabin and forepeak

Stepping down the companionway there is a full dinette to port which drops down to make a full double berth. Outboard of the dinette are multiple storage areas with Teak panel doors. The 12 Volt DC and 110-Volt AC Blue Seas Systems distribution panels, Air X wind generator control panel, and the Blue Sea Systems Tank Monitor are located outboard above the dinette. Aft of the dinette via a lift up seat back Teak door is additional storage.

To Starboard as you come down the companionway steps is a large storage area with a Teak panel access door.

Moving Forward is the main cabin with the Perkins 4-108 Engine and Velvet Drive transmissions located off center-line in a Teak engine box with full 360-degree access panels.To starboard is a full length settee . To port is a single full-length settee. The two (2) potable water tanks, approximately 50 gal, each are located under the settees. The 55-gallon Cross Link Poly diesel fuel tank is located below the main cabin sole and accessed by two large Teak & Holly sole panels. Forward on the Bulkhead is a Dickinson direct vent CNG gas fireplace heater mounted on a green marble backboard and a stainless-steel heat shield. The fireplace has a small tempered safety glass viewing window and a 12-Volt DC blower which circulates the warm air throughout the cabin for the chilly spring or fall mornings. There are abundant drawers, hanging lockers and a Teak framed opening “butterfly hatch” with glass panels, stainless steel grate, and a drop down Teak framed copper hatch screen.

Moving Forward - you have the choice of passing through to port to the head or to starboard to the master stateroom via exquisitely carved Teak doors.

To port is the full-size head which features a Jabsco 12-Volt DC macerating head, storage, mirrored vanity and a stainless steel sink which drains overboard through a seacock. Forward of the head is a full-size shower stall with a handheld hot and cold water shower fixture and towel storage.

To starboard is the master stateroom.The stateroom has private access to the head, storage and separate door rather than going back into the main cabin. The master berth can either be a large single or pulled out to make a comfortable double berth with a six-inch-thick mattress cushion. There is a hanging locker and storage areas with Teak louvered doors, shelving and a large mirror. There is an opening Bowmar Ocean hatch with a tinted lens and a drop down Teak framed copper hatch screen.Ventilation is abundant throughout the entire boat.

Moving forward through a custom sliding Teak door you enter the “crew” area with a port side single berth with storage under. To starboard is an oak counter work area with two (2) draws and a hanging locker. There is an abundant storage above to port and starboard with Teak louvered lift-upward doors. Oversized scuttle with Bowmar Ocean hatch with a tinted lens. The anchor locker is accessed forward via Teak louvered door.

Hull Speed
7.3 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.


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

7.34 knots
Classic formula: 7.58 knots
Sail Area/Displacement
<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.


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.
<16: under powered
16-20: good performance
>20: high performance
<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.


Ballast / Displacement * 100

<40: less stiff, less powerful
>40: stiffer, more powerful
>350: ultraheavy

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.


D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
40-50: heavy bluewater 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.


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
<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: 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.


CSV = Beam ÷ ³√(D / 64)

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