OUPV and Master licenses are issued with routes that describe the body of water that the license has authority over. The most common two routes are Inland and Near Coastal.
An Inland route includes all federally navigable inland waters of the United States, shoreward of the COLREGS Demarcation Line. The COLREGS Demarcation Line is the dividing line between where the Inland and International Rules of the Road apply. In general this is a line drawn between the seaward ends of the harbor or river entrance. You will find this line on the chart and it is also defined in back of the Navigation Rules book and in 33 CFR Part 80 of the Code of Federal Regulations. In addition to all federally navigable Inland waters an Inland route also includes the Straits of Juan de Fuca, Puget Sound, SE Alaska, and the Inside Passage through British Columbia.
A Near Coastal route includes all federally navigable inland waters of the United States and all ocean water within 100 miles of the coastline for the OUPV license and small uninspected passenger vessels, and all ocean waters within 200 miles of the coastline for the Master license and inspected passenger vessels. This means that if you need to operate a passenger vessel one inch past the end of the jetties at a harbor entrance you need to hold a license endorsed for a Near Coastal Route.
To qualify for an OUPV Near Coastal you need to be able to document 360 days of total qualifying experience that includes 90 days on ocean waters (seaward of the Demarcation Line and not in the Straits of Juan de Fuca, Puget Sound, SE Alaska, or the Inside Passage through British Columbia) over the course of your lifetime.
To qualify for a Master 100 ton or less Near Coastal you need to be able to document 720 days of total qualifying experience that includes 360 days on ocean waters over the course of your lifetime.
I have courses available that will satisfy the exam requirements for the upgrade of any license as OUPV, Master 100 ton or less, or Master or Mate 200 ton or less from Inland to Near Coastal.
