I've always regarded 20' as the dividing line between "small" and "big" boats - probably due to the need to keep the big ones in the water for the most part.It is strange what people consider to be a small boat
I recently resigned my column at small craft advisor because I now have a 26 footer
which in my mind is a large boat - until I take it to a Solent Marina where it is dwarfed by the 30 foot twin wheel scoop sterned cheese wedges in their serried ranks.
As for "How far", Webb Chiles sailed most of the way around the world in an open 18' Drascombe Lugger. When that was happening I remember thinking that proved there was no lower limit on the boat, only on the skipper.
