Seller's Description
This rare fixed-keel version provides incredible stability and windward abilities. The boat also was said to be unsinkable due to positive flotation from injected closed-cell foam in the interior compartments and between the hull and liner. Its a great boat design for a small family, someone starting out learning to sail, or even short-handed sailing.
The Tillster was rigged for single handling and racing by a previous owner, so halyards are run aft to cabin top winches with a second set of winches aft for the spinnaker.
This boat was updated in Spring 2021 with interior birch woodwork, tiller, companion door, LED navigation lights, mast wiring for LED anchor light and antenna. The following were re-bedded: windows, lifeline stanchions, teak hand rails, and hatch frame. The interior has DC lighting and a fan. A pop top provides extra head room in the cabin while at anchor and includes a like-new, snap-on bimini type cover with vinyl windows and a zippered door. Interior photos don’t show cushions in place, but they are in VG condition with new foam and neutral color. She points very well and is a fun boat to sail in “spirited” conditions.
Equipment: Sails: 110, 130, 155 and 165 and symmetrical spinnaker. Tiller autopilot, new condition pop-top cover with windows and zipper door. Trailer overhauled 2021, like new. Honda outboard extra.

Calculations

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
- ?
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
- ?
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
- ?
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
- ?
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
- ?
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
