Seller's Description

This is a 1996 Manta Catamaran that was damaged during Hurricane Dorian. The boat was hauled out for a refit prior to the hurricane so all damage happened while the boat was up on blocks, meaning no salt water submersion what so ever. It has two new Yanmar 30hp diesel motors that were added during the haul out, one with 185 hours on it and one with 175. Other upgrades that were added at this time include a new Kubota generator and a new air-conditioning unit. The main damage is in the fiberglass as the boat was knocked off the blocks. We were quoted $8,000 plus materials to have the fiberglass done. The boat was de-masted during the storm. The mast was broken in two but can be spliced and repaired and is with the boat. We are not sure the current state of the rigging or sails in terms of what is included. Several of the hatches need to be replaced. The boat has good bones and has the potential to be brought back to life for a cruiser looking for a quality mid sized catamaran at an affordable price. The boat is located within a secure boat yard in Marsh Harbour. All storage fees for the boat yard are currently paid up to date and will continue to be until the boat is sold so you will not acquire any hidden fees with it. Unfortunately, things have changed for us and we have not been able to get to the boat to do the work on it. We are asking for $50,000 so we can break even on what we have invested into the boat. I will email several more photos upon request.

Calculations

Hull Speed
12.4 kn
Classic: 8.37 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

12.41 knots
Classic formula: 8.37 knots
Sail Area/Displacement
31.4
>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.
31.4
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
97.8
<100: Ultralight

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
97.77
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
8.8
<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
8.82
<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
3.6
>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
3.57
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Based on an earlier design (FREYDIS) by Erik LeRouge.
Extended version of the MANTA 38.
Extended further for the MANTA 42.
