And just to say that if only sailing in England (British Waters) that the boat does not need to be registered. (only need registration
for a boat if going "foreign" and that only because foreigners want a bit of paper).
But in practice, getting any boat registered on the SSR is cheap
and easy and quick (only need to be a UK resident, with an address - and send a cheque).....you could probably get a lawnmower registered......but it keeps the foreigners happy!
Also whether registered or not a British boat (non-commercial) has no minimum equipment
levels - and therefore no constant Govt inspections to check if you are sitting on the toliet correctly. You could climb into a bathtub and quite legally set sail to Antartica - even fitting a bath plug
would be optional!, simply down to you to decide.
