Need #boat help! Anyone know what the largest (in feet) #sailboat is that one person could reasonably sail on their own? Money is no object (and let's say it also has an auxiliary motor, but would mostly be under wind power)

Bonus points for links to said kind of boat, but not required.

@colorblindcowboy I regularly sail my 10m (33’) Albin Nova single handed. Not crossing oceans, but I’ve sailed half way round Ireland.
A friend sailed a Hallberg Rassy 36 round GB on his own.
With powered winches you can sail a much larger boat single handed, but it gets trickier.
@OrangeMenace Oh, thank you. That’s great to know. I think 30-feet souunds just about right for this story.
