IMO the short answer is yes. A trawler type boat will offer more space than a similar size sailboat. You will know if you are "too old", I doubt you`d consider this if you were. Maybe go a little bigger than 30ft. You are experienced and not put off by the loss of the 28ft trimaran. You sound adaptable, go for it,keep enjoying doing what you like. Now!
