G'day,
 
I used a bridle from the bows and adjusted it so the join was near enough the middle of the boat.  Worked pretty well, but the boat still blew around in the wind a lot more than the monos so I dropped a bucket in the water and tied it to the aft beam.  Slowed it down a bit more.  Two anchors will not help much as the boat swings before the warps get tight and take the load.  You could try one from each end and keep them fairly tight but a big scope is required.
 
regards,

Rob

Hi,
 
Just meant swinging around on the water, like anchored in the sea breeze comes in 20knots.
 
I was wondering about general ideas about swinging around coming from experienced multihullers out there. Like when you anchor a bigger boat out further where the wind is. What about two anchors 30 degrees apart?
 
Mast is same as boat - kiri strip and glass.
I've tapered the tops to half dimensions. There is a round pole up a metre and a half into the mast that slots in the hull. I hope it is all not going to break.
Obviously it is heavy but is cheaper.

Dear Doug,
 
 
Dear Wangkas,
 
Nice pictures and all, but where is a finished sailing boat?
            We know it takes a long time, but sometimes we have other worries on our minds … like carbon spars for classical yachts where we have to sort out two boats, masts, booms, sprits, poles etc,  we have to make molds and plugs for rudders, keels and bulbs, … for the carbon parts we are achieving and testing  a construction method VAPM (vacuum assisted pressure molding that gives us autoclave quality laminates (not only on the voids ratio but also on the compression side) in our pressure molds( compression +-5 Bars) which can produce one piece parts, which is not possible by standard autoclave procedures. We are also currently testing a method for direct CNC mold cutting for parts construction …
Also, what do you hope to acheive with around beam?
 They are not only rounded in length but also elliptical in section and will be constructed VAPM… less windage, better stress distribution, less wave interference …
Thanks again for your mast section, it is coming together.
            We are glad, how are you going to construct it ? …
The boat really swings around at the moment without masts up and I wonder if it can be helped? More a question for the cruising boaters - do you plan doing cruising Elementarries?
            What do you mean with swinging around ? I suspect we will but that depends on the interest shown … for the moment we have some asks for quotes from France, Switzerland and Germany …
 
 
Best regards,
