how big is your yat really ???

According to the original marketing blurb, my dufour 40 is:

Waterline length 10.74m (35' 3")
Hull length 12.06m (39' 7") and
LOA 12.32m (40' 5") - which I'm guessing includes the stemhead anchor roller, but not the anchor itself (so probably about 12.5m, or 41' all in).

In my home marina I pay for 12.5m. Everywhere else I am 40' (which is 12.19m).
 
More complicated than that. Some marinas charge by measured length, some by area (L*B), some by berth size or more commonly for visitors by what it says on the registration document. So making sure you get it "right" when you fill in the form for your SSR is important. Less flexibility with Part 1 as the length is determined by the tonnage survey.

Builders use length measurements in a cavalier way, usually to indicate how the boat fits into peoples' perceptions in the market they are targeting.

Many if not most marinas here charge by LOA as measured between two plumb lines hanging from the extremities eg pulpit , self steering gear etc. The standard LOA is recorded in certain documents and they wanted to charge me at a higher rate. Several years ago I changed my pulpit for a shorter one which brought me down a category. Notionally the boat is 9m20; actually it's 9m48 as measured.
 
Does no-one on this forum have a conscience? If you don't want to pay for the proper length, buy a smaller boat. Everyone knows that marinas charge by overall length. Don't be surprised if they measure your boat to eradicate the fraudsters!
 
My boat is actually 21'9" LOA, so she happily fits in the ' sub 7 metre ' category at a lot of places; I wonder if I ought to fit ' Anderson 21' 9" 6.7 metres graphics on the side ?!

I've never seen marina staff anywhere actually measure a boat, but there are marks on the pontoon at some places...

They came and measured my boat. They measured got 20.3m.

They were concerned that the berth they allocated was not really long enough as a neighbour a couple of berths down (professional charterer who goes in an out twice a day every day during the whole of summer in a long keeled twin masted schooner), complained that my bowsprit was making his manoever to get in and out of his berth difficult.

They made me move a couple of berths further away from him.

I pay for the 15.6m LOA as written in the part I registration document.

Same when visiting elsewhere. I have never been asked to pay for 20.3m.

I think most people can easily spot the difference between 15.6m and 20.3m.

Not every marina charges by overall length, although it is common in UK. My marina (in UK) charges storage ashore by area. Area is also common in Europe, as is a fixed price for size of berth. Most marinas in the Med require sight of the registration document and use the length on there as a basis for charging, particularly for visitors, although they may well measure for longer term contracts. Makes sense, otherwise they would have to measure every boat that comes in - even for one night.
