Guys no history with windsurfing , what Im after is info for a standard length of a the windsurfer mast .
Was thinking to try and pickup one to use as a spinnaker pole , would need full length of about 3M

They are typically in 2 pieces, with the total length between 3.7 and 5.2m

Why one piece? You could just glue the ferrule on a 2 piece mast...?

How strong do u need it? Old school one piece fibreglass masts are free by the truckload ..... but would be about 1/3 the strength of a modern carbon mast.

why not just cut the mast (or 2 piece) to 3 meters ??

Do you need this to make a conventional spinnaker pole (i.e. double ended) or a sprit for an asymmetrical?

If it is for a double ended pole, I suggest you search on the Buy & Sell for top sections for sale. See if you can get two top sections the same or at least having matching inside diameters at their base, then get a ferrule made that will sleeve inside both. Epoxy them together and you have a nice double tapered pole.

Yeah thanks guys and this is what Im trying to do , wanting light two ended spinnaker pole , have a four metre for light winds in aluminium
but wanting something lighter and something that would cause less damage to top deck which happens when your swinging around trying to
get connections to ropes and mast attachments , heavy wind pole needs to be around the three metre mark.

The two top ends joined seem like a good idea , just worry about the strength , which will be used on a 31 foot yacht.

I wouldnt be aiming to use a windsurfing mast to make a spinnaker pole.

windsurfing masts comparative to a purpose made spinnaker pole, are as bendy as a piece of spaghetti

strong, but way too much flex to hold a kite steady.

For a 31 ft yacht you may be better off sleeving together two bottom sections rather than two top sections. And use a spectra bridle to the ends of the pole to attach the topping lift to, rather than attaching the topping lift in the centre of the pole. That way it takes only compression loads rather than bending loads.

Trouble is we break bottom halves more often - free top sections seem easier to come by.

Sorry guys I forgot to say even though I have been calling it a spinnaker pole it will just be used for the Jib/genoa downwind.

Dreamliner. I know there aren't many windsurfing shops left over there, but, check on the net, and if you're near one, drop in, and I'm sure that they'll help.
At 2ndWind, we sell quite a few sections to the sailing industry, for a variety of uses.
