2. Trailering hours shall be counted towards underway limitations for
designated boat crews.
B.15.a. Sheltered
Anchorage
B.15.b. Crew
Hours for
Multiple
Platforms
Time spent at a sheltered anchorage can extend the maximum underway
hours for crew on watch by 50%. Time at a sheltered anchorage may be
counted as “crew on watch.”
Although the maximum underway hours varies from boat to boat, crews
who perform missions on multiple boat types should not exceed 6-10
hours underway in a 24-hr period. Ultimately, the CO/OIC must make
an informed decision based on boat types, environmental conditions, and
crew fitness / ability.
