sailboat a keel
The keel has two main functions: to keep the boat from being blown sideways in the wind (lateral resistance) and to hold the ballast. the ballast is a weight traditionally at the bottom of the keel that keeps the boat right-side up.. The deeper the fixed keel, the harder it is for trailering. should your fixed keel sailboat exceed 25 feet, then you can’t trailer it at all. you’d need to keep it in a boatyard and launch it from there. this can be expensive and inconvenient. weighty boat: another problem with fixed keel sailboats is the keel adds extra weight to the boat. The keel also carries ballast, usually iron or lead, the weight of which counteracts the force of the wind that causes a sailboat to heel, or lean over. on a modern boat, the keel is shaped in the form of an airfoil wing to generate lift, which helps it sail closer to the wind.. 
sailboat a keel A common type of sailboat keel is a full-length keel, which uses length rather than depth to provide a sailboat with a proper amount of life and ballast. when it comes to the location of the rudder on a sailboat with a full-length keel, it’s often attached to the aft (rear) of the keel.. Lifting keel sailboats are also easier to launch and recover from a slipway, as well as to load and transport on a trailer. one main drawback of lifting keels is the added complexity, which many sailors regard as unnecessary. the keel may lift mud and pebbles that can get stuck in the keel box, potentially causing damage to the system or.
