Knee: a short L-shaped piece of wood that joins or strengthens the joint in boat parts that meet between roughly 60 and 120 degrees. It may be a natural crook from a suitable wood species, sawn from a larger piece of timber, or laminated to size. Commonly used on thwarts to join topsides or keelsons to join transoms.

In this episode I explain and shows how to glue laminate the wooden keel for the Haven. The white oak keel must bent over the floor timbers. Typically the ke...

Jan 8, 2013 · The fundamental structure of a plank-on-frame vessel is defined by a keel, which is the horizontal backbone of the hull; a more vertical stem, which forms the bow; and a vertical sternpost (plus, in the case of many yachts with long overhangs, a much less vertical horn timber that terminates in the transom), which forms the back of the boat.

Keel and Sternpost. Your designer probably calls for a white oak keel, properly air dried. This is good; he could have been much more specific, and gotten us all in trouble. He might have inherited from his Naval Construction days one of those little electric moisture-content indicators, and gotten all excited about what it told him.

Aug 18, 2023 · Wood can absorb and distribute stress, making it ideal for withstanding the forces exerted on a ship’s keel. Additionally, wood is relatively lightweight, which helps to maintain the overall balance and stability of the vessel. Different types of wood can be used in keel construction, such as oak, teak, and mahogany. These woods are known for ...

Keel – the underside fore-aft backbone of the boat running at the very bottom of the structure and usually the heaviest timber. Horn Timber – the aft part of the Keel connecting between the Ballast and the Transom. Deadwood – A filler piece between the Keel and the lead Ballast at the bottom of keel appendage

Dec 6, 2024 · Light Steel Keel: Made from high-strength steel plates, light steel keels offer excellent compressive and bending resistance, making them widely used in modern construction. Wooden Keel : Made from natural wood, wooden keels provide good workability and traditional aesthetic appeal.

If the boat is wooden, it will most likely have a wooden keel. If the boat is metal, the keel will be metal, and so on. Sometimes, particularly on fiberglass boats, the core of a keel will be reinforced with lead or a similar ballast while the outside is covered with fiberglass.

Aug 17, 2021 · With the boat being pretty flat bottomed, I am considering adding a keel to improve the stability, probably bolted to the main spine or backbone that protrudes about 4" from the bottom of the boat. I have very little experience in this area and I'm looking for advice and tips to try and reduce any rolling in anything other than river sailing.

Sep 5, 2006 · My options for keel material are limited in the middle of corn country. I have scoped out mahogany (1x6"x8' =$30 + lots of laminating and seams), 1x12x8 Ash ($50 and some laminating) and 5/4 Red Oak (1" true x 12" x 8' = $45/board) which would only require routing out for the swing part of the keel (3/8-1/2" steel) and is nice and heavy in itself.
