Re: Same X and Y scale

[Francesco]

I apologize for the inconvenience.
I read a review of its boatdesign.net of 15.07.2012 on the 747 by David Raison with some attached images produced from SW Delftship and some attachments with hydrostatic calculations.
I thought that they had produced her.

What I found interesting is that the idea of ​​raison has designed a multi-hull tankers to be rigged.
actually have two hulls joined by a central third.
As the images attached to her.

I simulated with Navaldesigner the hull of Raison and the wet surface decreases with between 25 ° and 35 ° while maintaining good coefficients, and above the waterline substantially longer than with a sailing center that advances and retracts when sailing upwind downwind.

I would like to play the same concept of an IOM hull – FIS 1m.
not a copy.

Sorry for my horrible English

THE IOM class rules of the class are:

C.4 BOAT
C.4.1 DIMENSIONS
With the boat floating in fresh water:
minimum maximum Draught ………………………………………………………………….. 370 mm ….. 420 mm

The depth of hull from waterline …………………………………………… …….. 60 mm

Hull length …………………………………………………………………………. …. 1000 mm

C.4.2 WEIGHT

minimum maximum
The weight of boat in dry condition excluding wind
indicator if used …………………………………………………………. 4000 g
C.4.3 CORRECTOR WEIGHT(S)
Corrector weight(s) to achieve compliance with C.4.2, if used, shall be fixed in/on the hull and not be altered or moved during an event.

C.6.4 WEIGHTS
Keel, excluding fasteners to hull …………………………………. 2200 g ……. 2500 g
