Seller's Description
Spencer 35 was built in Vancouver, BC in 1963. It is solid fiberglass with no coring. This model of boat was sailed in the books “Two on a Big Ocean” and “Two Against the Horn” The Spencer 35 is a fully capable blue water cruiser. The hull shape is a Norwegian folk boat design similar to an Alberg. This boat is state registered in the U.S. Right now it is located in Cancun, Mexico. Marina dues are paid through June, 2025. Marina dues are $330/month. It is already located in the Caribbean so you can start living the good life without having to sail there. New - Bottom paint, hull paint, dingy, foresail, interior varnish, upholstery and curtains, furler. The Bad - Engine has to bled each time you start it. Cockpit needs new paint.
Equipment: Engine - Yanmar 3HM35F 35hp Diesel Dingy - Achilles Haplon Outboard - Tohotsu 3.5hp 2004 Power - Air breeze wind generator, 2 solar panels, 3 deep cycles batteries, one starting battery. Navigation - Raymarine chart plotter, Raymarine radar, AIS enabled, 2 Simrad autopilots. Rigging - Swageless rigging, two speed self tailing wenches, mast steps to spreaders, Profurl furler. Sails - Fully battened main sail, 80% jib, 150% jib Galley - 2 burner propane stove, electric 12/120V refrigerator.

Calculations
- Hull Speed

6.7 kn
Classic: 6.7 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
- Sail Area/Displacement
-
15.7
<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.
- Ballast/Displacement
-
35.0
<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
- Displacement/Length
-
342.9
300-400: heavy
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
- Comfort Ratio
-
32.7
30-40: moderate bluewater cruising 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
-
1.7
<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
Notes
The SPENCER 35 MKII version featured a new, foam cored deck, molded toerail/hull-to-deck joint, extended coachroof with smaller cockpit, modified rudder, slightly different rig among other minor changes. The basic hull remained the same.
Thanks to Josh Shepard, SPENCER 35 owner, for providing corrected information on this yacht.
