This is perhaps the biggest thing that confronts any Single Mould Origin class..

How Genuine is the Mould in current production & how close it it to the original..

Without the Master Mould to measure against this is purely a copy of a copy.. " becoming diluted by fourth fifth and even sixth generation copies with all the faults becoming compounded with each generation"

How many Master Moulds have been flopped from the Master?

The IE12 in Australia is merely another such Copy...

Notice to buyers of hulls and boats:
New hulls are registered through the approved manufacturers above.
Unregistered hulls and boats cannot be registered without verification they were approved at the time of manufacture.
Hulls and boats that have never been registered with the Class from Dumas Products, Graves Little Boatyard and The Boat Shop cannot be registered.

In saying this I am continually concened that the Profile & measurement of the Keel area is ALWAYS AVOIDED & OVERLOOKED.

This is the Single most important area allowing the weight to be lowered within the boat & has an immediate effect on righting ability, tacking & heeling etc..

Wider at the base means ability to place weight lower..

If this is governed by the Mould & is supposedly a singular shape then all Keels should be identical & can & shoud be measured..

So what are the measurements.

From the original photo it appears to be a fairly strighforward measurement.
