The form says that I have to send in my current certificate. Any idea how long I will be without a certificate? And next time could I renew it six months early so that it's winter while I don't have one?
I sent a copy. Call them, they are not as stuck up as the form suggests, a lot more pragmatic.
My certificate has the wrong depth (by a long shot). I told them I could send a measurement certificate or other confirmations of the error. They said, no, I had to get it remeasured. As if!
You may be confused by the fact that the measurements for registration don't necessarily agree with the physical measurements of the boat.
The measured draft for a Pt1 tonnage survey is nothing whatever to do with the actual draft. Same as LOA or beam for that matter although that's usually a lot nearer.I may be. My maths was never that good. However I suspect even I can distinguish between the correct draft of 1.8m and the stated one of 1.41m.

It is an archaic system. I think the surveyor is meant to measure length and beam in a particular fashion but imagine the builder's hull length and beam won't be far out. I think commercial ships only measure length to rudder shaft instead of LOA, yachts are probably different.Not sure why length and breadth should be as stated on the certificate but draft not:
Length: 11.22 metres
Depth: 1.41 metres
Breadth: 3.50 metres.
Depends on the boat. My new boat is actually 13.3m LOA. Tonnage Measurement of LOA excludes the swim platform and bow roller so it’s measured at 11.63.It is an archaic system.

Manufacturer's don't quote the Depth measurement as it isn't really relevant and it is not the same as draft (see posts #9, #11 and #12).
I am not very surprised that your length and beam are the same as the manufacturer's figures. Mine are the same as the quoted hull length and beam. The manufacturer's LOA is 0.34m longer than the figure they give for the hull, the surveyor isn't interested in bits hanging over the bow and uses their hull length. He only measured the depth because it isn't something a manufacturer would quote.
Depth would only be the same as draft by a complete fluke i.e. Deck to bilge (or whatever the surveyor actually measures) and keel to waterline being equal .

Surely the marinas all go on the actual length not what's on some certificate? If it was a few cm different nobody would notice but approaching 2m....?
So if I turned up in my 13.3m boat with 11.63 on the Reg Cert they'd just charge me for the 11.63 / put me in the 12m bracket? What about if I had a dinghy in davits? Or a 12' bowsprit (pretty unlikely to be fair)?France, Portugal, Spain, Italy - every marina asks for the ship's documents when you go in to pay. Being 11.22 meters, it puts me into the 12m bracket rather than the 11 meter one if the certificate didn't have the .22.
