Kevin McCready 31 Posted January 21 Share Posted January 21 from my sailing database: Mr Earp gave evidence that he knew of people who started construction on a boat and registered the vessel several years before launching it. The registration is not an annual fee, it is a one off payment. Builders will do this so they can place the number within the hull. The requirements for a metal vessel are that the number needs to be stamped into the hull permanently or welded onto the metal hull or transom and displayed on a continuous beam inside the vessel. The metal plate is about the size of a cigarette carton and has an O.N. O/N or “Official Number”. Mr Earp gave evidence that most people prefer to do this while the vessel is under construction and agreed it would be unusual to do this without there having already been some construction of the boat being undertaken. the vessel was constructed structurally to Class 1B of the Universal Shipping Laws Code in 1995. The impact of this, on the value of the boat, is that it is in the region of 20-30 per cent more valuable than a non-approved design. It affects the overall value of the vessel because of the commercial potential. The classification 1B is a passenger going vessel considered to be suitable for offshore operations up to 200 nautical miles from land or safe haven. Quote Link to post Share on other sites

vic008 17 Posted January 21 Share Posted January 21 My yacht came with the OT number carved in an overhead frame.I think it means you are listed with Lloyds of London (no idea why). I am not on the NZ register(meaning cant race with NZY,cant go overseas,no sail number,no sole rights to boat name) You can search the NZ register on line for your boat name/number. A fee for change of owner. Quote Link to post Share on other sites
Island Time 807 Posted January 21 Share Posted January 21 The tonnage is not displacement, but the theoretical cargo tonnage, known as Thames Tonnage. Often carved as NTxx . Island Times one is 13. No way she weighs, displaces, or could carry 13 ton, but it's a measurement of the space inside. IT'S actual displacement is 7-8 ton dependent on load. 1 Quote Link to post Share on other sites

vic008 17 Posted January 22 Share Posted January 22 So does anybody know of any advantage of having a number? I can't think of any. Quote Link to post Share on other sites

Your boat must be registered if you want to sail overseas. See the link to Maritime NZ that I posted previously. Quote Link to post Share on other sites
Fogg 245 Posted January 22 Share Posted January 22 Overseas trips is really the main advantage - or if you’re selling the boat to someone contemplating it. Clutching at straws the only other ‘advantage’ is that as a registered Maritime NZ vessel you officially qualify for protection by NZ navy vessels (or their allies) if you ever needed it. Maybe piracy issues if you were travelling - but again you’d need the number anyway to depart! I have NZ registration for a slightly different reason - mainly because it made it much easier to explain to Malaysian officials why Fogg was being sailed through a restricted area and loaded onto a cargo ship for export to NZ - during a lockdown period in that region. By having NZ registration paper it made Fogg qualify as commercial traffic not pleasure traffic - thereby allowing my delivery crew free passage both during the delivery and on their journey back home. Lots of triplicate papers + lots of official stamps + lots of fees (you get the picture)! Quote Link to post Share on other sites
vic008 17 Posted January 22 Share Posted January 22 Am I confusing NZ Maritime with NZY.Can you go offshore with NZM, but dont need to be NZ Y registered? Quote Link to post Share on other sites
Dtwo 135 Posted January 22 Share Posted January 22 You don't need this O/N stuff to be NZ registered. https://www.maritimenz.govt.nz/commercial/ships/registration/part-B/default.asp As for the "tonnage", my understanding is that it started with ships being measured for how many standard barrels they could carry - i.e. tuns https://en.wikipedia.org/wiki/Tun_(unit) Then things morphed to where we are now. So it has nothing to do with displacement, everything to do with how much volume is available for stowing barrels. As in, pretty meaningless for yachts. Quote Link to post Share on other sites

To do an international voyage you must be a NZ reg ship. That's maritime nz. YNZ have nothing to do with that. Quote Link to post Share on other sites

Jon 159 Posted January 22 Share Posted January 22 Where YNZ come in is they issue your Cat 1 cert ( required for all NZ registered vessels) However they do this under contract to MNZ Quote Link to post Share on other sites
vic008 17 Posted January 23 Share Posted January 23 So, be registered with MNZ. (and no need for number carved in beam,) and get cat 1 from YNZ(no need to be on their register)and good to go. Quote Link to post Share on other sites

Although technically once you have been issued with the Maritime NZ registration number you are supposed to display it somewhere visible on your hull - they define font size and other details when they send you your registration. Also, there are 2 registration options Part A and B. A is for commercial vessels but for a private vessel seeking registration simply for offshore purposes you only need Part B - which is about $500 from memory (A is about $3-5k I think depending on your size).

KM... 952 Posted January 23 Share Posted January 23 No one checks so don't deface your boat due to some cock womble paperwork dribble. Also these days the old school 'protection' of NZ registered ships by all Commonwealth countries is purely up to the skipper of the boat that could provide protection. If they have better things to do you will be left hanging. It's a old school scheme that is now just a blend of Big brother meets an easy no stress income. The cheapest Commonwealth country to register in is Nigeria. Quote Link to post Share on other sites

Under Part B you have to display the registration number NZ XXXX on the outside of the hull. Part A requires you have the vessel's name and port of registry on the stern and the ON permanently fixed to the vessel's main beam. Part A is not just for commercial vessels, also anyone with a private vessel willing to shell out the initial payment, currently $2,205 for an existing vessel under 24 m (for some reason a new build is cheaper). Part A is lifetime as long as the vessel remains under NZ ownership Fortunately the previous owners of my yacht registered her Part A so no renewal fees and had a very nice bronze plaque made with the ON which is fastened to the mast support beam.
