WebDec 8, 2024 · Roll is how we describe the tilting motion of the ship from side to side. Wind and waves push against the ship and cause it to rock back and forth. Yaw spins the ship on an invisible middle line similar to swiveling on a chair. This can be caused by waves moving in perpendicular to the motion of the ship and can change its heading, or direction. can notaries perform weddings in texasWebBecause the water plane area changes shape and size with draught the position of the LCF will also change with draught.
