Seller's Description

1993 Gemini 3400 Catamaran was built by Performance Cruising and designed by Tony Smith! They only built 44 of them! Here is your chance to snag one of these!

The first of the Gemini’s to have molded fiberglass transom steps on the back of the hulls. This was also the first year that they introduced a lifting underhung rudder system.

The Gemini Cat is rare with real keels and two Yanmar diesel engines!

It also has three separate berths/bedrooms and a central dining table that drops down into a bed for guests. A nice bright blue canvas upholstery and teak wood tabletop!

The master cabin has a king-sized berth and the two double berths are located in the hulls aft.

The galley in the starboard hull is ready for you to make meals with a three-burner stove with an oven. Plenty of prep space on the long countertops and a double sink! Lots of drawers and cabinet space to store plenty of supplies!

The head is a decent size with a shower and a sink!

The headroom is 6’ 3” for all the tall sailors out there!

Calculations

Hull Speed
10.2 kn
Classic: 7.4 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

10.15 knots
Classic formula: 7.4 knots
Sail Area/Displacement
19.6
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.

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.
19.6
<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
125.7
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
125.74
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
11.7
<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
11.65
<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
2.8
>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
2.8
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

The GEMINI 3400 was the predecessor to the GEMINI 105 and the first in the series to have molded transom steps. A new kick-up rudder system was developed for the new transom design. Like all Gemini models the 3400 has kick-up centerboards which are housed in low aspect ratio fixed keels which serve as protection for the under-slung rudders from damage when grounding.
