    Sounds like you are making good progress.

    I remember as a kid practicing casting in the garden. The neighbor was not impressed when he saw me casting platic worms at his cat. Those things dont only work on fish!!!(Before the SPCA arrives to take me away, there were no hooks involved).

    Actually it's frustratingly slow :eek:

    Got very little done today. Laser cut pieces (touch wood ) arives tomorrow.

    I have decided to make two one piece beams, 500mm wide (fore and aft) that goes to the the amas instead of using the pipe method, so you can walk to any of the side hulls or even fish from them. Seems I'm always taking the long way to do things.

    The laser cut pieces arived. I can finish the furling roller tonight. Already welded an experimental anchor, will have to find a sand patch to test it in.

    Floated the hull in the pool today, I'm impressed, it sits right on top of the water. One thing I noted was the slightest of breezes moves the hull. Without anything to support it floats on it's side without taking on any water.

    The beams foam cut, will glue and start glassing them tomorrow. After that the amas... for some reason really not looking foreward to making their jig...

    The beams are glassed but green. Have to finish the ends off still. It keeps on threatening to rain and the wind blew my work area full of leaves. Last night it was flying ants... Beginning to feel like the seven plagues ;)

    Wife helped with the 2nd beam... much easier if you have more hands.

    The glassing the beams was more work than I thought they would be.
    I ordered some white 2k paint that was delivered this afternoon... typical SA without the hardner.

    I ordered two extra extrusions, both larger than what I had to make the mast stiffer. Should arrive tomorrow.

    The sail should also be done by tomorrow, so things are slowly comming together.

    When I've done the amas I can make the mountings for the beams measure the sail out etc.

    Small draw-back, the furling roller first attempt is a nice bugger up. Welding the disks buckled them badly, too much heat required to weld them. I may have to make some 'ventilation holes' around the welding area to restrain the heat. Will figure it out...

    Furling roller done ! (tick) The holes drilled around the welding did the trick. If I redo them I'll just change the laser cutting.

    Got the sail earlier today... I feel like a sailor already ! ;) The furling roller fits nicely to the sail cable.

    Also received another piece of mast extrusion to stiffen the mast some more.

    The beams are four meters long and since yesterday went from a green to a more ripe :rolleyes: stage. I can support the two ends and it carries my fat weight in the centre... bends just slightly.

    The amas jig steel sections cut... bending then welding them together.

    Sounds good, you are progressing well. When do you plan to be finished by?

    The amas jig is finally done. I've made some changes from faults picked up on the centre hull's jig. The foam, although half the thickness of the main hulls's foam, drapes much smoother. Depending on a lot of thing I could get one hull, maybe both done tomorrow.

    Tuks, I suspect a couple of days yet. I have to determine the mast's position. The beams have to get a slot in the centre hull where I can bolt them down and the same for the amas. The centre hull needs a keel or fin on it's belly and I still have to make a rudder as well. Some kind of seating would probably be more comfy than to live in an empty shell. To answer your question, Monday ! Just not sure which one :D

    I would really like to take it out really soon, just to play with and get a feel for it. This time the pool will be too small.

    Fanie, I find trampolines to be very comfortable and a couple of years age "ferari cloth" seemed the favourite for durability. Make sure it can be stretched (by the weight of bums and time) by re-straining the tiebacks?

    Thanks Masalai, I have sailed with a friend on his windrider, I got the trampoline position. It wasn't bad, but it was a bit on the short side for me and not very comfy to relax on witout having some part :rolleyes: dragging in the water. For now I just want to get the basics done and take er out for a spin.

    You people with big overhangs (dicks) are a problem. Make sure it is at least enough for a couple to go to sleep on. drop the sails and do some lovemaking. beats waterbeds outa sight.

    What, the big dick or belly? with or without sex as a pommie may ask whilst pouring the tea.

    Laterally if you are becalmed (sailing wise) and out in open waters surely. Remember, though I think someone explained there is a minimum time at sea per voyage to count. Some require the captain to verify your log book entry. When you are a captain - or maybe lower - depends on local country laws I think you are trusted to make your own verification. Is this drivel? Oops off topic again. If your home is a boat. Jackpot!

    I cant believe how quickly you are building this boat, but I will be blown away if you can make foils, sort out rigging, bolt down fittings, and all the other stuff by Monday. Im just hoping to see some pics before I go on holiday;).

    Search google for "new generation yachting", I spoke to Joe. He makes alot of beachcat trampolines, so he can probably help you out. He was pretty cheap too.

    I have been thinking about this aft mast rig a little and I have two concerns.

    1. Controlling Forestay Tension.
    The depth of the sail in a jib is controlled by the amount of forestay sag. To depower the sail you pull on more rig tension which makes the forestay straigher and flattens the sail. A freestanding mast will not work because the mast will flex and you will not be able to achieve sufficient forestay tension. The stays will need to be fixed to the boat behind the mast. The smaller that offset, the larger the tension required in the rigging and the larger the compression in the mast. This means that the mast will need to be a significant distance from the transom which means lost sail area. I think you are going to find controlling the sail shape difficult and the loads on the boat are going to be pretty big. Have you calculated this yet?

    2. Balancing the sailplan as you reef.
    I have no hard data here, but I think as you furl the sail, when overpowered, your COE will move forward quickly and may result in lee helm. My hunch is that when reefing a mainsail, the COE moves forward at a much slower rate. You may have issues with keeping the boat balanced.

    I have not read up about this rig much so maybe these are not such big issues. I found this pic, just for inspiration

    Tuks, the tri is 4 meters wide, I doubt if it will need to be kept balanced.

    There are a lot of things I have to figure out yet, since not many so called boat building experts seem to be active on the forum you can ask.

    One side hull glassed... one to go. If I have enough energy left I may do the other later today or tonight. The rate the sun cures the glass is unbelievable.


    WRT the sail, an extension to the front may add a lot of space. A flexing mast is a concern, but I'll figure it out as I go. There may be space for support.
