part 1 proves tonnage. this might be useful if one is charged light dues etc when in far flung parts of the globe.i do not think it proves ownership but interests ie morgages can be recorded.certainly much more expensive and only lasts 5 yrs.i registered under part one because like you i intend extensive cruising. i am not sure that it was money well spent. certainly have been readilly accepted by customs immigration in europe but i guess that is same with ssr?
Yes, the owner is the person on the register. It's a bit like buying a house in an area (which most are) where there is registered title.
It's interesting that most people don't bother to register ownership of their boats where they would never dream of doing the same for their houses.
Personally, if buying a boat, I would be very wary of buying one that wasn't Part 1 registered unless I was 100% certain about the history of the boat to convince me that the chap I was handing the money over was really the owner of the boat. Even then I would be paranoid that his wife etc. might be a part owner. General practise in the UK however is just to hand over the cash and hope. Fortunately, most people are blissfully unaware of the very substantial risks they run. Part 1 registration eliminates the risk.
Banks aren't so crazy, so insist on Part 1 reg before lending money.
I'm not sure if you're looking at a Part 1 or an SSR certificate. If it's SSR, then registration on the SSR has little to do with ownership. If it's Part 1, then the certificate is not proof of ownership, it is the entry on the Part 1 register itself which is the proof. The statement is made to stop people assuming someone's the owner, and perhaps parting with lots of cash, just because they wave what appears to be a Part 1 certificate, without checking what is written in the register.
A bit like title to registered land, where you are issued with a land certificate, but it's the entry on the register that matters, not the certificate.
With some registers you have access online, but only to see if a desired name for a boat is already taken (which, of course, tells you also that a boat of that name exists), as far as I am aware no register goes further than that online (but there may be some).
But, just like a land register, you can have the register searched for which you need either just the vessel name (if it is not a secondary register which allows dulicate names) or its official number.
Some registers will verbally give you uncertified information about the boat, say by telephone, and may also do so at no cost. But normally one would have the register inspected by oneself or a representative, or request a certified transcript of what is on the register (which includes mortgages and the owner), or in the case of some registers get an uncertified printout from the register. For all those there is usually a fee.
There may be some variation in practices according to the specific register.
In my opinion one should always have the main register (Part I in UK) inspected in the case of intention to purchase any reasonable sized boat whether it is claimed by the seller to be on the register or not.
People should also be aware that simply looking for the carving and marking on the boat to see whether it is on a register or not is not foolproof. Some registers do not require boats under a certain size to be carved ie official #, tonnage, and some do not require the marking ie the name, to be "permanently made" on small vessels nor on other larger vessels where the marking would detract from its appearance (eg high quality yachts). In any event it is easy enough to remove the "permanent" marking and carving from any boat even if cut or welded (as is required on larger vessels).
If a boat on the register is purchased it must have its ownership changed and this can only be done with the consent of the previous owner. If it is on a register upon which it is no longer possible to keep it or it is desired to put it on another register then that must be attended to. The register will have standard forms for all of these things. Of course, there is a charge /forums/images/graemlins/mad.gif. I have seen it said on these forums that those things don't matter or will look after themselves - obviously a stupid claim to make and may end up with costly arguments later in life.
