Hol up. Sailing culture is VERY different from RV culture. I lived on a sailboat for years, going up and down the US coast, startup hopping. The sailing culture is very friendly, especially to kids (who are treated more like small adults than children). The people I met along the way are life-long friends. If I needed a ride to an auto store to pick up new house batteries, engine parts, or even to a Walmart, there were always people to give me a ride.
RV culture is much more lonely and expects people to be more self-sufficient. If you need help, there may or may not be people to help you; for sure, the whole campsite won’t jump to help, unlike a marina.
At least, that was my experience.
