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)

Formerly FLYING DUTCHMAN JUNIOR, FLYING JUNIOR. As of 1980 the name was officially changed to INTERNATIONAL FJ. First built of Fiberglass in 1960. A ‘Club’ version (CLUB FJ) is of heavier construction with approximately the same dimensions. There have been a number of other variants including the DEMON, a stretched version of the same design, and the PIRATE, said to be a FJ hull with a TASER deck and seen mostly in Canada. (Formerly listed here as FLYING JUNIOR (INTERNATIONAL FJ).) Spinnaker Area: 8m2/86 sq.ft.

The Club FJ is a tough, agile performer for beginners to elite sailors. The Club is a fantastic choice for clubs and junior programs looking to introduce young sailors to double-handed sailing with a spinnaker. Our Collegiate version (no spinnaker) is the most popular boat in college sailing.

Introduces young sailors to double-handed sailing The Club FJ is a tough, agile performer for beginners to elite sailors. The Club is a fantastic choice for clubs and junior programs looking to introduce young sailors to double-handed sailing with a spinnaker. Our Collegiate version (no spinnaker) is the most popular boat in college sailing; more collegiate sailing teams in North America sail our FJ than any other double-handed sailboat.

The International Flying Junior or FJ is a sailing dinghy which was originally designed in 1955 in the Netherlands by renowned boat designer Van Essen and Olympic sailor Conrad Gülcher. The FJ was built to serve as a training boat for the then Olympic-class Flying Dutchman. The FJ has a beam of 4’11” and an overall sail area of 100 square feet (9.3 m 2 ). These dimensions make the FJ an ideal class to teach young sailors the skills of boat handling and racing.
