We are a couple in our mid 50s planning to retire into living onoard a pre-own trawlers in about 10 yrs. Never owned a boat. But preliminary research told us to take some basic courses with the USCGA or US power Squadron, then attend a paid trainning course with a local trawler charter and school outfit. Get some hands on experience and charter a trawler ( most probably some Grand Banks classis ) for a few weeks and then decided whether or not to get our feet wet. If we get thru this stage, we would like to purchase a pre-own pilothouse trawler ( love those pilothouse ) . So far we loved the DeFever PH long range trawlers of the 80s, prices seeed right now, could even get cheaper 10 yrs from now. Kadey Krogen 42 is reachable too. Nordhavn 46 is also under consideration. The above 3 models are plentiful enough on any given years to make purchase choices easier. We will not be financing the boat. Most likely refinance the house, buy the boat, live on a reserve funds set up especially for (1) refit (2) fuel (3) dockage pre-planned for about 5 years. ( Planned on based around the Cheasapeake Bay area m but sail north to the great lakes and Canadian Maritimes in the spring and summer, and after the hurricane seasons, head south to the Carribean in the spring. Most probably will do The Great Loop once .) Then sell it and move back on land and buy a RV to roam America the beautiful on wheels as we get older. Any suggestions on DeFever 49' , K-K42 or NH46? Do we need an annual refit? Or once when we take delivery, once in mid-term, and once before re-selling it will be fine? Thanks in advance of any advices from you more seasoned sailors.
