Parker 31, 325 and 335 actual LOA?

[mogmog2]

The numbers ascribed to boats by the manufacturers seem to have a somewhat free association with the actual size. Yesterday I was reading that the Bavaria 34 " is actually 36 feet long." Then there's the difference between the original meaning of "Length Over All" which isn't actually overall length. LOA is officially (to naval architects) the distance from the bow, excluding any protrusion, to the after face of the rudder post where it appears on deck. To a marina however, overall length is the distance between the furthest forward bit of the boat, or anything on it, and the furthest rear bit. So an 18 foot hull as we would understand it may actually be charged for 32 feet if it has a 10 foot projection of a bowsprit and a piece of the gaff or boom sticking out 4 feet beyond the transom.

No one's ever measured our boat (marinas nor me), places just ask the size and I give a number and it's accepted.

My boat’s declared length is 10.4m and as far as I’m aware most places (including my home berth) charge on that basis. Two examples that don’t are Lymington town quay who round up or places that charge in bands such as Littlehampton

As it happens, Lymington is one of the (few) places we've just put into and maybe where I saw the "... nearest metre" and .
And also as it happens, our boat's kept in LA but I have a to pay the harbour dues with my eyes closed, so I've no idea how they do it. Rounding up to the nearest metre would be small beer compared to the base rate

The harbour commissioner’s policy can mean in practice there is little difference between rafting up on the town quay or being in one of the marinas.

With the 8m to 11m band for visitors at Littlehampton, something at the very bottom of that scale may find berthing in the Solent cheaper.

I didn't know about the bands, that's even worse. They've lost the plot IMO (lots of other stuff too).
We're across the river, so berthing fees are sane club prices, just the harbour dues element is "on the high side".
Every season we have the discussion about moving to Chichester or Langstone , but the boat's only 15 minutes from us and that's a big plus.

Seems the same applies with annual harbour dues, it was rather annoying last year when half the visitors pontoon was given over to the large Fisher and an ex RNLI lifeboat despite them advertising spaces on the residence pontoons.

I have a theory that your downstream hammerhead may be at chart datumn so at very small neaps could accommodate a fin keel boat but doubt I would be allowed to try.

IDK, if you emailed the club you could ask - they're accommodating and not officious. The only objection I could think of is from the maintenance team: if your hypothesis was incorrect and the boat partially dried and leaned it would put possibly excess load on the finger. Trying to think who might be worth asking....

Isn't it funny (peculiar) that measuring of small crafts is defined by an

International Standard​

• ISO 8666:
  This international standard defines how to measure the principal data of small craft, including maximum length (Lmax), hull length (LH), and waterline length, using reference planes and clear definitions for structural parts

Yet there are endless variants, often driven by financial interest and practised by all sorts of "specialists".

Add to that the messy business of marketing, where boats can have names that indicate (very) different dimensions than the actual ones?

I'd always assumed that contrary to nearly everything else that's sold at us, manufacturers downplayed the length in the model name (but haven't rigorously tested that. Or even at all , although the Parker 325 is one example)

Review of Parker 275 - www.yachtdatabase.com

The Yacht Database has an extensive list of many boats and is well worth a trundle though ... just enter the boat you are interested in ...

Yes, but where do they get their data from? How reliable is it as the source isn't identified?
I'm sure brokers just copy the data from the easiest source online and I suspect all these yacht data sites do the same - a self-referencing circle of potential error...

Incidentally, that site you suggest definitely has errors - I contacted them to correct something about the Centaur, can't remember what now, but in the dialogue I offered them a photo - it's our boat shown. Review of Westerly Centaur - www.yachtdatabase.com
