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)

One of the most popular one-design classes in the US since the 1940’s. But fleets also exist in other parts of the world. Although originally designed for wood planked construction, nearly all boats since the early 1960’s have been built of fiberglass. Ballast above is max weight of centerboard.

About International Lightning Class Association

The Lightning truly excels as an affordable racing boat. The rig is simple but offers sophisticated sail shape controls. The hull features a unique hard chine design that combines the stability that provides sail-carrying power, with flat bottom sections that promote planing. At 700 pounds all up, the trailerable centerboard sloop is tough enough to avoid frequent breakdowns, but light enough to plane wildly on the reaches. Membership is diverse with sailors aged 8 to 80+. Many families sail together at top events and it is common to see females make up at least 40% of competitors.

The Lightning is sailed in more than thirteen countries and in the Pan American Games. A World, Master World and Youth World Championships are held every two years. North American, South American and European Championships are held each year as are innumerable regional and District championships. Major regattas attract some of the finest sailors in the world, but you find Class members friendly and the sailmakers’ complete tuning guides helpful at getting you up to speed in a hurry.

The International Lightning Class Association is one of the oldest and best organized class associations in sailboat racing. Its primary purpose is to serve its membership, preserve the integrity of the Lightning and provide high-quality competitive events. In addition, the Lightning Class publishes monthly e-blasts and a quarterly newsletter Flashes with up-to-date regatta news, boat brokerage and ideas on how to get the most out of your Lightning. The professionally managed association and dedicated volunteers are always on hand to assist both current and potential members.

If you’re looking for a boat you can be proud to sail, one that offers dinghy handling with the performance of a sport boat, a refined design that’s free of fads, complete with the technology of today for both racing and day sailing – look at the Lightning.

About the DN Iceboat

The Lightning offers a combination of performance and stability that eludes most one-designs. The Lightning’s hard chine and 130 lb centerboard give her the stability and power of a small keel boat going to weather in strong winds and allow her to carry a very large spinnaker for breathtaking off wind rides. The Lightning’s rig is simple, but offers sophisticated sail shape controls. 

Our 19-foot trailerable centerboard sloop has evolved into one of the most popular and competitive one-design racing classes in the world. Awarded ISAF International Class status, the Lightning is sailed in more than 13 countries and in the Pan American Games, and the class provides a professionally-managed association that is among the largest in all of one-design sailing. 

If you’re looking for a boat you can be proud to sail, one that offers dinghy handling with the performance of a sportboat, a refined design that’s free of fads, complete with the technology of today for both racing and daysailing – Get The Best Of Both Worlds. Get into a Lightning.
