Seller's Description

This 1984 Nelson Marek Morgan 454 Stay-Sail Sloop is ready for you to take offshore or to just harbor hop around your favorite bay. Her Keel/ Centerboard design, with the centerboard sealed inside the keel, allows you to anchor out in the skinny waters of your favorite gunkholes.

The boat has extensive upgrades with major engine work complete with fewer than 200 hours since repairs.

She has upgraded heads, new bilge pumps, and new freshwater pumps along with a full galley with propane stove/range, Diesel cabin heater, and an A/C unit that fits over the forward hatch,

Down below, you have two cabins with double beds and two heads with showers, and a roomy main salon with pull-out couches that can sleep additional 3 people.

Equipment-wise, she has an 8-man emergency life raft and a full-color Garmin 12” - 4 K Radar/GPS/Depth finder, with forward and aft seeking depth sounding.

The boat is I.O.C rigged with 8 winches and a 63 ft. Mast. She has lots of sails and tons of spares.

Don’t wait too long to arrange a showing or make an offer prior to traveling to see it. This unit in this condition will sell fast!

Calculations

Hull Speed
9.6 kn
Classic: 8.12 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

9.6 knots
Classic formula: 8.12 knots
Sail Area/Displacement
18.1
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.
18.11
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
44.2
>40: stiffer, more 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

44.22
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
202.5
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
202.46
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
27.6
20-30: coastal cruiser

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
27.63
<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
1.9
<2.0: better suited for ocean passages

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
1.9
<2: better suited for ocean passages
>2: better suited for coastal cruising

In the used boat market, sometimes referred to as MORGAN 454, NELSON-MAREK 454, etc.
Morgan model names in this size range are especially confusing and inconsistent.
(This model was also advertised as the MORGAN 46, even though there was another of the same name, a cruising ketch, designed by Henry Scheel and also built by Morgan Yachts.)

This design was ‘recycled’ into a number of other models including a center cockpit version, MORGAN 43 (1985).
After the demise of Morgan Yachts, a later, significantly modified version was built by Catalina Yachts.
