$599,000 USD

Seller's Description

SOLD 2018 Seawind 1160 – “Fantasea” now for sale. $599,000 The Seawind 1160 LITE is designed to be lighter and faster providing good performance for the sailing enthusiast, but yet modern minimalistic apartment living for coastal live aboard.

At just 6.5 tonne it is more than 30% lighter than similar sized cruising catamarans and this is achieved by resin infused foam core construction, foam core furniture and doors and outboard motors. This 2018 Seawind 1160 LITE comes equipped with Twin 25hp Yamaha motors with low engine hours, with electric tilt to reduce drag and maintenance, plus EFI data input into your B&G chart plotter.

The Navigation equipment includes a B&G chart plotter, AIS, Rada, VHF, and Epirb with various multi functional displays, plus a Lewmar chain counter for your electric windlass controlled from the helm. Plus the sails are controlled from an electric winch at the helm. There is 800 watt s of solar panels on the roof with a MPPT Solar regularly and 60 amp battery charger, powering 450 amp hours of AGM low maintenance batteries. The cockpit also features twin helm seats, BBQ, side clears and with a shade cover that can be rolled out from the boom.

Inside and the saloon features a modern interior with charcoal trim, with TV and Bluetooth Fushion stereo and 12 volt fans for comfort. On the port side there is a neat office while on the starboard side, a large galley with plenty of storage, stove and oven plus filtered drinking water tap alongside the fridge and double chest freezer. There are three comfortable cabins, each with privacy screens and insect screens, 12 volt fans, plus an ensuite in the starboard forward and a large separate shower and head in the port aft .

There is also a Rainman watermaker that is hardwired and plumbed into the hull of the boat.

AMSA SURVEY COMPLIANCE OPTIONAL This 1160 Lite has been modified to include 800mm high safety rails with a hard top rail for additional safety, which will also allow for a conversion to AMSA survey. So if charter operations in Sydney or the Whitsundays is of interest, talk to us about optional survey compliance. The boat comes with Seawind Factory Warranty.

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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.
?
<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
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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: better suited for ocean passages
>2: better suited for coastal cruising
