Pleasure craft can be considered to be vessels that are used for sport or recreational purposes only and do not operate for any financial gain to the owner. A more extensive legal definition can be had by reference to the Merchant Shipping (Vessels in Commercial Use for Sport or Pleasure) 1998 as amended.
This document gives advice and some detail on what regulations apply. More specific information can be obtained by consulting the relevant regulations or by contacting the MCA.
