Seller's Description

Manageability is the cornerstone of the Beneteau 311. Easily sailed by a crew of one the 311 is beautifully balanced on the helm. In fact, the 311 while having super large cockpit and swim platform also doubles as a great club racer. She is FAST even though she sports refrigeration, lazy jacks, bimini, and cruising items such as autohelm self-steering.

Vessel Walkthrough: The Beneteau 311 features beautiful cherry woodwork throughout. From the companion way the galley is to port, with stainless steel sink, two burner propane stove and oven, and top opening dry goods storage locker. The refrigerator is to starboard and the lid forms the working surface of the navigation station which has the 110 Volt and 12 Volt electrical panels, Standard Horizon VHF radio, AM/FM/CD Player stereo radio, and 12 Volt outlet. The large main salon has a centerline folding leaf table and settees to both port and starboard. The private v-berth has a double bed and hanging locker storage compartment. Aft of companionway on port is the doorway into the huge aft stateroom that also has a hanging locker. On starboard is the large head with shower and Jabsco toilet. Both the galley and head have hot and cold pressure water.

Calculations

Hull Speed
9.4 kn
Classic: 7.18 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

9.39 knots
Classic formula: 7.18 knots
Sail Area/Displacement
22.1
>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.
22.08
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
31.4
<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

31.43
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
146.1
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
146.1
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
17.4
<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
17.37
<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
2.1
>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
2.13
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Keel-CB vers. draft BU:2.58ft/0.8m, BD:7.08ft/2.15m
Ballast with CB: 3,085 lbs/1,400 kg
Rig dimensions with roller furling mast:
P = 36.29ft/11.06m
Sail area with roller furling mast = 481 sq ft/44.7m
Same as Oceanis 311.
