*Minimum safe speed* means the speed at which a vessel proceeds when it is fully off plane, completely settled in the water and not creating excessive wake or surge. Due to the different speeds at which vessels of different sizes and configurations may travel while in compliance with this definition, no specific speed is assigned to minimum safe speed. In no instance should minimum safe speed be interpreted as a speed less than that required for a particular vessel to maintain steerageway. A vessel is not proceeding at minimum safe speed if it is: ( 1 ) On a plane;
( 2 ) In the process of coming up onto or coming off a plane; or
( 3 ) Creating an excessive wake or surge.

( c ) *Security zone.* A 500-yard security zone is established around each escorted vessel within the regulated area described in paragraph (b) of this section. This is a moving security zone when the escorted vessel is in transit and becomes a fixed zone when the escorted vessel is anchored or moored. A security zone will not extend beyond the boundary of the regulated area described in paragraph (b) of this section.
( d ) *Regulations.* ( 1 ) The general regulations for security zones contained in § 165.33 of this part applies to this section.
