What about a few more details in your Bio, like where you live etc.
Roberts 44's are big boats. I would be checking whether the foam sandwich extends down below the waterline. Lots of advantages of foam sandwich but plenty against them too. Roberts 44 sold here a few months ago and went to New Zealand. One day out they had to return with a crew member with a broken leg. They flew out a replacement crewmember, they had 5 in the crew. Not a singlehanders boat by any measure.
Some examples of large boats.
