6 Liveaboard Trawlers 70-Year-Olds Singlehandedly Captain Without a Crew

Great Harbour N37 — At 36 feet 10 inches, this trawler is built around an apartment-style layout that older solo owners praise for its full galley with household-style appliances, a walkaround queen berth, and a salon comparable to boats 10 feet longer. Twin Yanmar diesels deliver roughly 2.5 nautical miles per gallon at 7 knots, giving a range over 2,500 nautical miles. Its shallow draft and protective skegs make it viable for skinny-water anchoring in places like the Bahamas, and its wide-open systems access lets aging owners handle their own maintenance instead of hiring help.
