Just got Ericson 25 and wish to bring it south to CT from Marblehead. My sailing experience is pre-GPS/chartplotter. If I were to buy something, what would be wise and reasonably priced? I note people sailing with multiple handheld GPS and chartplotter and such and am confused. How many pieces of equipment do I need - what type, etc? I expect be a New England cruiser until kids get out of college.
One other question, if I devote my available weekends to bringing boat down from Marblehead to Old Saybrook, what am I looking at (assuming good weather) in terms of 8 hour legs?
Any thoughts, I appreciate.
