One data point we have not sought, but should have, is exact knowledge of all current rudder-only weights, rather than rudder+box weights. So, we ask all members, as soon as convenient, to WEIGH YOUR RUDDERS please, separate from the rest of the structures and report that information to me via email or text. I’ll take separate parts weights too if you have them (rudder, box, tiller). We will use that information to make target weights and variations for the vendor who has been very good at working with us on such details and will make the class database of boat weights more complete. We will have to trust your bathroom scales are at least close!
Modern masts form the leading edge of a sail's airfoil and tend to have a teardrop-shaped cross-section. On smaller racing yachts and catamarans, the mast rotates to the optimum angle for the sail's airfoil. If the mast has a long, thin cross-section and makes up a significant area of the airfoil, it is called a wing-mast; boats using these have a smaller sail area to compensate for the larger mast area. There are many manufacturers of modern masts for sailing yachts of all sizes, a few notable companies are Hall Spars, Offshore Spars , and Southern Spars.
Regarding heliborne munitions, IMO, since we are tight in budget now maybe the cheapest way to up-armed the Kedahs is by arming the helicopters, that’s why I asked for opinions whether it is indeed more cost effective. Of course I am aware that arming the helis instead of the ship would not be as capable, but it could be an option for the time being. Once we have consolidated some funding, maybe we could armed the ship with missiles seeing that they are ‘fitted for but not with’ anyway. But if RMN’s intention is for the Kedah Class to be more than OPVs….
