Lee-boards are boards or plates that are attached to the side of
the hull of a sailing vessel to reduce downwind drift.

Leeboards are important for reducing sideways drift and for sailing across or into the wind.

Leeboards are for sailing

Leeboards basically are lifting foils used by sailboats. They function much like centerboards (or daggerboards), but are located on the leeward side of sailboats instead of under the center of the sailboat. The leeward side is used as that side allows the leeboards to dig into the water when the boat heels, as the sailboat will lean under the force of the wind.

leeboards are great fun

By slicing through the water with little resistance when going forward, but presenting large lateral surface area, leeboards help to prevent (or lessen) the boat from sliding sideways.

leeboards can convert a fishing boat into a sailing boat

Should your leeboard hit ground, unlike a centerboard, where your boat will come to a dead stop, the hull of the boat will do a spin around the leeboard when you ground it. Then it's a simple matter of pulling the leeboard up to be on your way.

leebaords are used a lot in Holland Netherlands

Leeboards are for preventing or lessening leeway, not to assist in steering the sailboat.

Leeboards were used a lot in the past

Want to sail a boat that doesn't have a centerboard trunk? You can make a simple pair of clamp-on leeboards out of wood and clamp them over the gunwales (the upper edge of the side of a vessel). The leeboards generally pivot on a bolt so it can be balanced for sailing.

Leeboards can be used instead of dagger boards

Lee-boards are similar to center-boards, but the lee-boards are mounted on each side of the hull. They can be pivoted down into the water to provide a shallow draft boat with lateral resistance, without relying on a center keel. The lee-board can be raised up out of the water to allow boats to pass through shoals, and increase the boats' speed when going downwind, when there is no need for lateral resistance.

Leeboards are mainly used in shallow waters

Just like centerboards, the leeboards are ideally shaped to act as foils. The leading edge is best rounded, with the thickest part just forward of the middle. The rest of the leeboard then gradually tapering down to a thin flat edge at the back.

Imagine using a leeboard in Florida or lakes

With small boats leeboard water tends to get trapped against the hull of the boat. Waves then can get squeezed in the passage between the boat and the leeboards and water can kick up into the air.

leeboards reperesent history

On most traditional leeboard designs, the windward leeboard is retracted when it isn't needed. Doing so tends to reduce drag.

We hope that you'll send us pictures of other leeboards as well.
