Seller's Description
(Price in Canadian dollars)
As we have purchased a larger sailboat, we must regretfully part with our much loved 1987 Tanzer 25. This is an excellent, extremely well designed boat that we have enjoyed immensely. It is a fantastic sailing boat, a wonderful performer in both light and heavy wind. In light wind it is extremely fast due to the large sail area, and handles strong winds and rough conditions very well. All lines run to the cockpit for easy handling, a large traveler and new ratcheting mainsheet blocks provide excellent control of the new North Sails mainsail, and brand new Harken self-tailing winches installed just last August provide excellent control of the very nice 155% genoa. The interior is impressive for a 25 foot boat, including a large aft cabin, aft head, central galley, and a forward salon that converts to a large sleeping area. It has an inboard Volvo Penta diesel that runs very well, and a Martec folding prop, fin keel with a 48 draft. It is a very pretty boat and has drawn attention on the water. This is an uncommon boat, with I believe less than 50 examples being produced. We have done a great deal of work to it during the time we have owned it, and hope that the next owner will appreciate the boat and continue to improve and enjoy it. As it is a 36 year old boat, it is not perfect, but many improvements and upgrades have been done recently, and overall it is in extremely good condition. The boat comes with an unused very good quality custom dodger and a bimini.
Items still needing to be done: new headliner, previous owner repaired port side bulkhead and chainplate in a functional but not cosmetically appealing manner. Should replace cabin sole with new teak and holly plywood at some point one sheet required.

Calculations
- Hull Speed

7.7 kn
Classic: 6.26 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
-
20.0
>20: high 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.
- Ballast/Displacement
-
39.3
<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
- Displacement/Length
-
180.5
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
- Comfort Ratio
-
13.9
<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
- Capsize Screening
-
2.4
>2.0: better suited for coastal cruising
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
A shallow draft version of the TANZER 25 was also available. Thanks to John Kriz for providing updated information.
Shoal draft: 2.82’/.89m
