Seller's Description

Sea Star was made to cruise oceans and many Beneteau 473 have crossed the Atlantic and more. It’s hull shape leads to a wonderful sailing experience. The aft cockpit is large and safe. Dual helms allow for good visibility and control when tacking as well as docking. Sea Star has the two cabin floor plan with 2 ensuite heads. The head off the main salon can be entered from either the salon or the rear cabin. There is also an extra storage room off the very spacious galley. It can also be accessed from the starboard side of the cockpit - and houses the robust Westerbeke generator with plenty of room left over for tools, sails, gear and provisions. The 473 was named Boat of the Year by Boating Magazine for 2001. She has a keel stepped mast, and unlike most 473’s SeaStar has dual 50 gallon fuel tanks (for a total of 100 gallons) and also 3 water tanks for a total of 150 gallons. You will not have to clutter your decks with jerry cans! The salon is spacious and filled with light and has quite ample storage. New AC in the salon keeps you very cool even in hot humid conditions. The Reverse cycle heat is cozy in winter or for nights up north.

We have enjoyed sailing her in the Pensacola area and have spent much of 2023/2024 upgrading her with safety and energy conservation as the foremost priorities. Changes in life circumstances require that she pass on to her next owners. SeaStar is currently at Yacht Harbor Marina in Pensacola FL

Hull Speed
12.1 kn
Classic: 8.87 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

12.07 knots
Classic formula: 8.87 knots
Sail Area/Displacement
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.


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
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.


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
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.


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
