Seller's Description

1978 Seafarer 26. This is a fantastic boat and I hate to part with her. New Mainsail 2023, New 150% Genoa 2023 with roller furler, some new running rigging 2024, New EVA foam in cabin 2024, New VHF radio (in box not yet installed), 2 working batteries, 2 Solar Panels work fantastic, shore power with cord, excellent trickle charger(although it’s not ever needed due to solar), self bailing cockpit, Westerbeke Diesel Engine runs like a champ, swim platform with telescoping swim ladder, bimini in great condition with window to see sails. Canvas covers for everything handmade by previous owner (windows, winches, etc), double pane portholes installed by previous owners keeps all totally dry, BOSE speakers with radio, depth finder and speedometer, Im sure there is more I’m forgettingwe own Altitude Video Production and there is a plethora of videos of this boat on our YouTube Channel at Altitude Video Production All she needs is some bottom paint and she is a dream to sail. The gem of this sale is the Aluminum Sailboat trailer worth the total asking price itself. It has all the bells and whistles including a telescoping tongue extension for easy haul outs for almost any boat ramp, upgraded pads for the boat, ladder at the tongue, locking box for chucks, extending and locking pvc pipe guides, etc. Asking 16K or best offer. Currently in dry lot at Lake Jacomo. Must be sold by April 1st.

Calculations

Hull Speed
7.9 kn
Classic: 6.39 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

7.91 knots
Classic formula: 6.39 knots
Sail Area/Displacement
15.6
<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.
15.61
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
38.6
<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

38.57
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
174.8
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
174.76
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
18.0
<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
18.02
<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
2.0
<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
1.98
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Shoal draft: 2.58’ / .79m
Yanmar (1GM) diesel available as an option.
