wing masts buoyancy aid ?

[TREVO SCOTT]

Hi all,

At the moment wing mast info is in fashion,and to the rc multihull people it may have been looked at.My thoughts are quite

wide of the designing mark,but the front wing would make a fair buoyancy aid instead of the mast top bottle/ball/or whatever.Two for the price of one

so to say.At the moment I have nothing in mind about it,although the weight may be a problem up top in high speed turn, maybe there would not be enough buoyancy in the front wing alone.Another thought is the smaller the multi the less likely it would be any use as a buoyancy aid.

So has anyone got any thoughts in this direction,because if it could be done it would make rc multihull racing quite interesting in windy weather.It

could even allow the multi to right itself by weather cocking round so that the hull is downwind,the wind then tries to force the hull over again and may let the wind under the sail.I have seen my rc multihulls do this without a buoyancy aid in heavy weather two or three times but that was before the wing mast made its appearance, in the A class, C class cats not to mention the AC 45s

What are the thoughts of other rc multihull sailors ?

Hi All,

I have being trying out a method of making the leading section of a wing mast on my Micro Magic monohull.All it is is a 3mm Depron wing just slightly smaller than required.

this so that it will fit inside a very large pocket luff.It can be tapered if required like an aircraft wing.The depron part has a light plastic tube through it to accomodate the 6mm carbon fibre mast and can be sealed to make it water tight.Its shape can be made to a known section shape just like an aircraft wing.I found out that the twin sail material of the pocket luff if left 5mm too long for the section was ideal for a smoothing the shape onto the transition to the single material out to the leech.I am at the moment ready to make a sail for my 65M multi.This time I aim to build to a planned  shape to see if it works as a good sail and of course any help as buoyancy when the multi is capsized,or if it would need to be a full wing sail to get the volume required or if my maths is not right !?? regards  Scotty
