Seller's Description

This 1978 Formosa 46’ Cutter Kelly Peterson design is ready to hit the waters

The owner has made lots of upgrades over the last year:

The Bottom Hull has been sanded down to gel coat and replaced blisters with 400 West System. 2 coats of InterProtect 2000E Barrier Coat System has been applied. 3-5 coats of INTERLUX-Micron 66 Antifouling Paint have been applied. The Top Hull got 2 coats of AwlCraft 2000 in Snow White.

7 House bank Batteries and 2 start batteries have been replaced with AGM. The fiberglassed enclosed chainplates were removed and replaced with an outside custom chainplate. The bent forestay and furling were replaced with Pro Furl System.

The old Lifelines have been replaced with new Stainless Steel. The Port and Starboard rear lower shrouds have been replaced.

It has a new dinghy and dinghy engine 20 HP in July of 2021.

It features a new Garmin depthfinder and Chartplotter radar, VHF radio with AIS has been installed.

Also, a new Victron 3000W Inverter charger has been installed.

Much more has been done to this Sailboat.

Dinghy included: West Marine 10’ 2”

Calculations

Hull Speed
9.5 kn
Classic: 8.43 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

9.48 knots
Classic formula: 8.43 knots
Sail Area/Displacement
14.2
<16: under powered

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.
14.17
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
30.3
<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

30.3
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
237.8
200-275: moderate

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
237.84
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
40.7
40-50: heavy bluewater 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

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
1.61
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Yet another altered version of the KELLY-PETERSON 44 (PETERSON 44 CUTTER), first offered in 1976.
(Often, as in this case, with out the payment of design royalties.)
To make the boat longer, it is said that builders simply added an incremental distance between each station on the original plans.
