Ballast takes many forms. The simplest form of ballast used in small day sailers is so-called live ballast, or the weight of the crew. By sitting on the windward side of the hull, the heeling moment must lift the weight of the crew.
The Principal-Agent Relationship. A principal-agent relationship is an arrangement between two or more individuals. Specifically, the agent of the relationship performs a task on behalf of the principal. This is often due to different degrees of knowledge and skills.
An agency relationship is generated by the consent of both the agent and the principal. No person can unwittingly become an agent for another. A written contract is common, but not necessarily essential when it is clear that both parties intend to act in their respective principal and agent roles.
