Auxiliary Sail Endorsement

What Is the Auxiliary Sail Endorsement?

The Auxiliary Sail Endorsement is an official add-on to your OUPV or Master Captain’s License that allows you to operate sail-powered vessels that also have an auxiliary engine. If you plan to carry passengers for hire on a sailboat—whether for charters, tours, or instruction—you’ll need this endorsement to stay compliant with U.S. Coast Guard regulations. Even if the vessel has a motor, if it’s primarily propelled by sail, the endorsement is required.

How Do You Get the Sailing Endorsement?

To add the Sail Endorsement to your current

license, you’ll need:

Sea Service Experience
You must document at least 180 days of service on sail- or auxiliary sail-powered vessels. These days can be part of your existing sea time if they meet the sail-specific requirement.
Application Submission
The endorsement is added through the standard USCG application process. We can help ensure your paperwork is correct, complete, and submitted on time.
No Separate Exam Required
Good news — there’s no separate written exam for the Sail Endorsement. You just need to meet the sea service requirement and submit the right documentation.

Why Add the Sail Endorsement?

The Auxiliary Sail Endorsement increases your versatility as a licensed captain and is required if you plan to operate sail-powered vessels commercially. With this endorsement, you can:

Operate sailboats commercially for charters, lessons, or tours
Carry paying passengers aboard inspected or uninspected sailing vessels
Meet USCG legal requirements for vessels primarily propelled by sail
Qualify to operate larger inspected sailing vessels
Enhance your resume and expand your job opportunities in the sailing industry
