    I can recommend Rudolf vd Brug for a carbonfibre mast. Contact him on rpvdb@freeler.nl.

    My mast is a gem, 20cm dia, 12,5m total lenght, weighs in at 61kg, acts like a shock absorber but still dont bend too much.

    Regards

    Ketil

    Nedal not interested in smaller quantities than 2000 - 2500 kgs, recommends contacting mast builder, John Mast in Denmark.

    Thankyou gentlemen, I'll pursue Nedal and if no result I'll look into the hybrid option.

    PS. Vanharouvas mast is a aluminium extrusion 150 mm with a reinforced GRP
    flagpole as topmast.

    Just sent a questioning mail to Nedal. I'll report if they answer.

    Atlantic Spars bought a stock of tapered tubes from Proctor, when they closed down. They originally came from Nedal, a large extruder in the Netherlands. I think my mizzen mast was made from the very last tube that Atlantic Spars had, and they weren't very interested in getting more stock.
    Last year, Dawn Smith was trying to get a price from Nedal, without much success. Go here and download a pdf brochure. What you need is the"Boulevard" model of lighting pole, and my size is actually quoted as 222mm. I see there is now a 202mm size. I believe that there is no difficulty in buying a lighting pole from them - but by that stage, they've ruined it for mast-making by cutting access holes near the bottom. Getting them to show some interest in supplying a bare pole was the difficulty, but the more people that show an interest and ask for a price, the more interested they might get.

    One thought that occurs to me is that the 222mm size is 17 or 18m long. My mast is 12m long, but 12.5m would have been better. You could try asking if that size of finished lighting pole has a bare, untouched length above the access holes in excess of 12,5m if they won't supply a one-off bare pole?

    The alternative is to do what Annie did, and make a hybrid mast of an alloy tube with a wooden topmast. You'd need a 200mm/8" thick walled tube - try phoning some UK stockholders to see what's available. It makes a good mast economically, and the diameter inside the boat is less than for an all-wooden mast, which is useful.

    Thanks Arne and David,

    Arne, I'll be living aboard and plan to go ocean voyaging. Probably not on an epic scale like David, but hopefully an Atlantic 'milk run' or two. So, mostly downwind trade wind stuff but with the occasional slog to windward when required.

    David, I suspected I might run into bury problems with a foredeck mast position. I was willing to accept the loss of a nice double bunk in the forecabin but I think your idea of a heavily forward raked mast in the vicinity of the heads compartment would be a good one. With adequate reinforcing I could possibly keep the existing forehatch (at the front of the coachroof) and have the mast passing through the coachroof just aft of the forward heads compartment bulkhead.

    The passagway to the forecabin is already offset to starboard so there would be no need to offset the mast.

    I know you sourced your mast from Altantic Spars (flag pole?). I've emailed them an enquiry but so far received no response. Are there any other UK suppliers of tapered alloy poles? And roughly what should I expect to pay for a suitable bare pole?

    I see that the sail area quoted here is 560 sq ft - not far from Footprints' sail area, so the design work is already done.

    Jerry,
    Congratulations on getting hold of a Rustler. Should make a very good long distance cruiser.
    You face the same conundrum as we did with Fantail - how to avoid messing up the sleeping cabin by putting a mast through it ? And I think the answer is the same, to rake the mast forward, and get the bottom of it into the heads compartment. 

    Putting it vertically through the foredeck seems to be too far forward for balance and for getting adequate bury, and also, the weight is rather far forward and anchor work will be more difficult.

    Raking it (and offsetting it a little to one side so as not to impede access to the forecabin) would put it quite close to the existing mast position, and the heel would be on top of the ballast. Adding some laminations of ply and glass onto the deck, to stiffen it up, would maybe cover up the mess that will be made by taking off the bermudan mast step. 

    I have to admit that this sailplan seems to have worked better on Fantail, with 6 degrees of forward rake, than it does on Tystie, with 2 degrees of forward rake. Footprints is in the process of going from zero to around 4 degrees of forward rake, so it will be interesting to see how that turns out. I think it will improve her a lot.

    I see she has 2.5 tons of ballast, not much less than Tystie, and she carries it lower, so will be stiffer. My mast is 220mm dia x 5mm wall, and I don't think you should go much below that - 200mm dia x 5mm wall at the least.
