Appendix C – Glossary
Engineering
Changes (ECs)
These are the only authorized modifications to a standard boat. No one
other than Commandant (CG-45) is authorized to approve ECs to
standard boats. The specific boat type operator’s handbook provides
amplifying details on the EC process.
NOTE
Engineering changes were formerly known as BOATALTs.
Extended Alert
Duty
Fatigue
Fatigue Waiver
A person is on extended alert duty when assigned for more than 24
hours. Generally, this occurs as the result of 48 or 72 hour weekends.
A condition of impaired mental and physical performance brought about
by extended periods of exertion and stress which reduces the individual’s
capability to respond to external stimuli. Some factors contributing to
fatigue are sleep loss, exposure to temperature extremes (hypothermia
and heat stress), motion sickness, changes in work and sleep cycles,
physical exertion, workload, illness, hunger, and boredom. While an
individual or crew may be considered to be fatigued at any time, at a
minimum, they are considered to be fatigued when they exceed the
underway or alert posture standards.
A waiver to crew rest or rest-recovery requirements granted by the
Operational Commander.
Functional
Configuration
Requirements
This applies to the operation of machinery (i.e. main engines, marine
gears, etc.) and electronic/electrical equipment. Minimum performance
requirements (full power) and operating parameters as set forth in the
applicable specific boat type operator’s handbook are functional
configuration requirements.
Heavy Weather
Seas (height) greater than 8 FT and/or winds exceeding 30 KTS
