How big does a boat have to be to be named?

The naming of a boat typically depends on its size and purpose, but generally, vessels over 10 feet in length are often given names. Traditionally, larger boats, such as yachts and ships, are more commonly named, while smaller boats, like canoes or kayaks, may not have specific names. Ultimately, the decision to name a boat is a personal choice by the owner, regardless of size.
