Vanguard 15
November 30, 1999 by Sail1Design Editor Leave a Comment
Labeled by some as the ideal post-collegiate sailors boat, this simple design is comfortable, easy to sail for beginners and a small family outing, yet also boasts one of the more competitive one-design classes in the US. The Vanguard offers plenty for the thrill seeker; the boat will plane upwind, and is a blast to sail off the breeze in bigger winds as it is relatively stable.
Another bonus of this boat is it’s simplicity. There is so spinnaker; only a jib and mainsail, and minimal controls make this boat easy and inexpensive to maintain. For these reasons the Vanguard 15 is very often the top choice for high-level team racing events. It is a great team racing boat!!
One design feature that is both a blessing and a curse; the foil is a daggerboard, which on the one hand makes the cockpit very open and spacious. On the downside, a daggerboard is a liability should you run aground, as damage to the board, and more critically, the hull, is likely.

Rig and Sails
Auxilary power, accomodations, calculations.
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.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
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.
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 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.
Ballast / Displacement * 100
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.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
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.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
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.
CSV = Beam ÷ ³√(D / 64)

The Vanguard 15 is a recreational sailboat, built predominantly of fiberglass.It has a fractional sloop rig with aluminum spars, a raked stem, a vertical transom, a transom-hung rudder controlled by a tiller and a retractable daggerboard.It displaces 200 lb (91 kg) and is capable of planing upwind. [1] [2] [5]The boat has a draft of 3.42 ft (1.04 m) with the daggerboard extended and 6 in (15 ...
A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing", International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.
Dubbed by many as the ideal post-grad boat, the Vanguard 15 has enjoyed continued success as a double-handed, one-design racing platform at both the club, national and international levels. The new standard for international team racing, the V15 is light, fast and easy to transport and sail. Combined with a reasonable price tag ($7,500 new, […]
Good article John, I loved the v-15 for the fun sailing, great social scene, and great class support from the builder. Vanguard did a great job to build the class and supported it to a tremendous positive outcome through partnerships with local events (chip johns at bbr), us sailing, and isaf to provide boats at hinman and team race worlds.
Another bonus of this boat is it's simplicity. There is so spinnaker; only a jib and mainsail, and minimal controls make this boat easy and inexpensive to maintain. For these reasons the Vanguard 15 is very often the top choice for high-level team racing events. It is a great team racing boat!!

The Vanguard 15 is a popular one design racing dinghy designed by Bob Ames. It is a double-handed monohull sailboat with a sloop rig. ... Its design allows it to plane while sailing upwind in 12 knots of breeze or more. LNYC V15 sailors race in the Dinghy Club series, Thursday night series and Friday Fun Sails. Travel regattas include the CYC ...
Vanguard 15 is a 15′ 3″ / 4.7 m monohull sailboat designed by Bob Ames and built by LaserPerformance starting in 1992. ... 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 Vanguard 15 is a well-designed, well-built, simple, and fast centerboard boat that appeals to both beginning sailors and experienced racers. It is raced with a crew of 2 but can accommodate another sailor or two for a day sail.
The first Abilyn, a Vanguard 15. As this was our first boat, we spent a considerable amount of time naming her even though her name was staring right at us through two sets of monozygotic eyes. ...
