Does anyone have the Nethercott hull as a cad file? if not then does anyone know its rise of floor measurement and max (deck) width?

Thanks

Alistair

I have a reasonable approximation (it has all the measurement points as stations) in a hullform file, but I don't know if that's any use to you. I have max deck beam as 1.01m. I can probably give you a rise of floor, but at what station and what distance from the centreline?

Hi Jim
Thanks for that. Two measurements at 2600mm from stern if you could
what is the width 100mm up from the keel?
What is the height above the keel at 750mm wide?

Just trying to compare the one design with the new measurement rules.

I did have the line drg of the nethercott but someone "borrowed" it and its never come back....

Thanks

Alistair

I'm away for a few days so I'll have to get back to you, but you haven't by any chance forgotten that the nethercott sections are on the last page of the class rules?

I have the profile and plan view of Bill Beavers No Go 55. I do not have the section shapes.
This is his optimized Nethercot, which measures in to the one design class, but is not the same shape as the DKV shape that most associate with the Nethercot.
The DKV is identified by the small near chine on the bow just about at the waterline.
There is quite a bit of tolerance +10mm in the One design hull rule, which also doesn't require that the height of templates be referenced to the Base line but to the hull. So if you are maximum distance from the baseline at a certain point on the rocker, you can place the template on the hull and still have 0-20mm gap between the template and the hull surface. This compounding of tolerances is not unusual and accounts for all of the "new shapes" in one design fleets.
SHC

You will probably have to send me your email so I can send it to you.

This is doing a bit of interpolation on my model, so no promises as to definitive accuracy, and bear in mind SHC on tolerances, but if I haven't stuffed up radically

> what is the width 100mm up from the keel?
804
(402 from centreline)

> What is the height above the keel at 750mm wide?
81

Sadly I no longer have an IC to measure definitive numbers from.
