    Ha ha Trev pipes!
    I think you may be right Philip they look a bit on the short side

    Brian the idea is that the pipes allow the air to pass down the tubes to the bottom of the hull when plough in happens the tubes need to go to the bottom like this

    Flush with the bottom of the hull so the air gets under the hull and helps to lubricate the underneath and prevent it from being sucked down onto the water and stopping.

    I fitted the pipes to my Osprey 5 last year and it worked well the craft did try to plough but it always popped back onto hover with no real slow down or plough in sudden stops.

    Trev, that looks like an interesting concept. Could you post a link to the original thread so that I can get caught up?

    FYI: a couple of years ago I played around in the same area on my Scat II and came up with this: I'm about to rip 75% of it out - trying something new again.

    Hi all, they were originally longer but then I can not get it off the trailer anymore!

    I was told to make sure they are below the skirt segments, so I interpreted that as below the skirt segments when they are laying flat on the hull.

    I thought when the skirt collapses the segments cover the air feed holes so these pipes allow the air to escape below the segments...If that makes sense…

    I have to admit that so far the only time I have felt plow-in was at the hovercraft museum in the bad weather on the last day…

    If they need to be longer than that I will remove them totally.

    Hi Brian
    the pipe has to be longer than the skirt contact point pulled back against the hull so the air can get to the bottom of the hull, Leave them on and see how it goes at Loch Fyne

    There is no original thread it was a article in a 20 year old HCGB mag that I read and decided to try my version of how i thought it could work with pipe I had lying around.
    You know the score, some hovercraft owners try there ideas out to see if it works and you have tried out more radical modifications than most of us I have to ask ,the skirt on your scat is it a improvement on the original segmented skirt Ie does your craft perform better now than a standard scat

    No improvement yet - far from it, in fact because I left the cover off one winter the foam soaked up a lot of water and the craft is way overweight now. I never got the flow and pressures right on the drape & bag skirt. As of last summer the craft has a sort of mini finger system with air flow from the bag. I'm planning on ripping out a lot of the work - anything which restricts the flow like those HVAC pipes is going in the recycle bin.

    I have "3 pipes" or landing skids which are hollow vinyl tubes running down the middle of my craft at the plow plane. It was not intended to have air running through it. I did it to avoid crushing of a transverse bag skirt just aft of the bow (tucked on top of the milk crates). In retrospect it could have acted similar to your pipes had I left the ends unsealed.

    back to the original topic.....Sewing

    I used 60 pound moss green SpiderWire (fishing line), hand sewn to reinforce heat welded seams on my thermal polyurethane skirt. The material required no reinforcement new, but after sitting around for a year in my basement it just would not iron up to full strength anymore. Also bonding to the fabric on the craft already weathered and exposed to UV rays had even weaker bonds, so I added spot point fasteners composed of plastic button-like automotive fasteners and aluminum washers pushed over the threaded ribs.
