    Jami,

    The  lower battens of the 35sqm sail on my IF are 35 x 2mm, and they cope well. Your sail is so much smaller and the boat so much lighter, so I think 35 x 1.5mm should be OK.  For batten 2 from top, I guess I would prefer the 35 x 2mm version, and maybe even for the boom.

    Arne

    The mast issue is still pending, but I would need advice on the batten sizes. They will be aluminium tubes, but would 35/2 or even 35/1.5mm be enough or not? 


    Any views, please?

    Alll right, folks - I have started crafting the sail by cutting panel patterns from thick paper.

    I'll go for Arne's sail type with AR=2.15 and sail area of about 27 sqm. The cloth will be Swela Outguard (190 g/sqm) in bright yellow :)

    It may still be needed to fill the step with something to make the transition smoother and ensure that the batten parrels etc. don't catch the step, but that isn't difficult to make. I use epoxy with some light filler in it, and then glass over it, no problem.

    Correct, the stepped poles from Nedal and others are flow-formed, like the conical poles. I guess it must be easier for them to run the machine along at the same diameter than to be making the diameter decrease as it runs along. When I mentioned separate tubes and a conical adaptor, I was thinking of the masts I've seen made this way, when full length tubes haven't been available.

    If you want to see how it's done:

    No separate poles - if you look ar the photo at the link below, you will see that the stepped ligting pole is manufactured as such.

    They seem to be available in 4 and 5 mm wall thicknesses in various lengths, although sold only in 6060.

    I see no reason why you shouldn't simply fair from one step to the other, with epoxy filler, or similar.  If the poles fit all your other specifications, the steps wouldn't really be an issue.

    It would be possible, though not ideal, to use a stepped pole. There are masts around that have been assembled from two tubes with quite a difference in diameters, and with a conical adaptor to allow the sail to slide over the join.

    Nedal is a big enterprise, and the extruder in the Netherlands, and supplies customers across the whole of Scandinavia and Europe. I would be very surprised if there were another one in such a small country

    What diameters?
