What is the purpose of 'pre-entry reconnaissance' when approaching an unfamiliar harbor?
Answer: To study the chart, locate hazards, identify channel markers, and plan the approach before entering
Pre-entry reconnaissance involves studying the chart, pilot book, and waypoints to understand the harbor's hazards, channel layout, and dock options before the vessel commits to entry.
What is 'DR track' verification and why is it practiced on offshore passages?
Answer: Comparing the dead reckoning estimated position to actual GPS fixes to identify set and drift from current
Periodically comparing dead reckoning positions to GPS fixes reveals current set (direction) and drift (speed), helping sailors correct their course for water movement they cannot see.
When is it appropriate to use a sea anchor (drogue) on an offshore vessel?
Answer: In heavy weather to slow the boat and keep the bow or stern into breaking seas
A drogue or sea anchor deployed off the bow or stern in storm conditions slows the vessel and keeps it oriented to the seas, reducing the risk of broaching or pitch-poling.
What is the standard VHF radio channel for hailing and distress in US coastal waters?
Answer: Channel 16, monitored by the US Coast Guard and required for all vessels
VHF Channel 16 is the international distress, safety, and calling channel; the US Coast Guard continuously monitors it, and all vessels are required to keep a watch on it.
According to ASA offshore sailing standards, what does 'COG' mean on a chartplotter?
Answer: Course Over Ground — the actual direction the vessel is moving relative to the earth
COG (Course Over Ground) is the actual track the vessel is making good over the earth's surface, accounting for leeway and current — it may differ significantly from the compass heading (COH).
What provisioning principle is essential for a US coastal cruising passage according to ASA 106?
Answer: Carry enough fuel, water, and food for the planned voyage plus a reserve for contingencies and delays
ASA 106 emphasizes that adequate provisioning — including reserves beyond the estimated passage needs — is fundamental to safe offshore cruising and crew welfare.
