Maine has a few instructors that are former tall ship master’s and the aux sail operations concentration… They have Schooner Crew that does maintenance on the Bowdoin and in the fall it does afternoon sails Monday-Thursday after classes are over. You could also get positions on tall ships during the last half of your summers after your cruises so that you graduate with enough time to get your 500 ton mate of sail. I don’t think they’re are any boats in the US civilian fleet over that tonnage so that’s really all you need
Star of India is listed as 1197 GT (no register tonnage listed)
Falls of Clyde is 3200 GRT - but the ship is tied up.
I wouldn’t consider either of those vessels a part of the US tall ship fleet.
“When she sails, Star of India often remains within sight of the coast of San Diego County, and usually returns to her dock within a day. She is sailed by a skilled volunteer crew of Maritime Museum members, who train all year. She has become one of the landmark ships in San Diego’s Harbor.”
