THE CREDENTIAL

Add the Auxiliary Sail Endorsement to a Master’s License

This endorsement can be attached to a Master’s license and specifically qualifies mariners to captain sailboats that carry more than six passengers for hire or are inspected vessels.

THE PREREQUISITES

Built for Experienced Mariners

Applicants must already have sailing experience; for the Master’s license itself, candidates must be at least 19 years old and document 720 days of sea service over their lifetime.

THE ACCESS

Straightforward Upgrade Options

Students who previously completed an OUPV course elsewhere and can show their certificate or a valid Merchant Mariner Credential may take the Master’s Upgrade, Auxiliary Sail Endorsement, and/or Towing Endorsement classes at the Antique Boat Museum without repeating the OUPV class.

Suitability

Who it's for

Who this endorsement is designed for — and who should wait.

1
Aspiring Commercial CaptainsIdeal for mariners aiming to expand a Master’s license so they can legally command inspected sailboats or vessels with more than six passengers for hire.
2
Experienced Recreational SailorsA strong match for sailors with prior time aboard sailing vessels who want the formal endorsement to pursue paid or inspected commercial work.
3
OUPV Certificate HoldersIf you have a prior OUPV completion certificate or a valid Merchant Mariner Credential, you may take the Auxiliary Sail Endorsement and related upgrade classes at ABM without re-registering for OUPV.
4
New Sailors or Incomplete-Service MarinerNot the right first step: candidates lacking sailing experience or the Master’s license sea-service minimum (720 days) should pursue prerequisite sea time and foundational courses first.
