    Moth foil profiles

    Continuous development, plenty has happened in 10 years, but I suspect the 63412 is way older than that. Trends: . less chord but similar span (around 1m) for higher aspect ration and hence better L/D ratio. . Bigger flaps for better control in waves and for bigger changes in lift coefficient...

    2022 Moth Worlds

    I understand Rob shipped a different boat from UK and the custom boat remains in Sydney. It was way too expensive to ship boats from Aust, so no ons did.

    2022 Moth Worlds

    The North sail Rob showed me last April had two battens in separate pockets at each batten location, and at the front end of each pair was a piece of webbing between the two. The webbing was slack enough to wrap around the back of the mast, separating the battens to the sides of eh luff pocket...

    Australian Skiffs

    Add to Rambler's comments: While well under canvassed to be regarded as a skiff the MG14s do have some reasonable fleets in Sydney and offer some skiff like rides with asymmetrical spinnaker, but no trapeze for the skipper. These do have the right age group and several women competing.

    Buying an old moth, a Bladerider. Mistake or not?

    My new ride, slower, cheaper and less crashes, but mostly no lifting.

    Buying an old moth, a Bladerider. Mistake or not?

    It can be fixed, but not easily. Many people grind off the carbon up maybe 100mm and lay up new carbon. Its not often successful because hand laid, low mod carbon and ambient temp resin is no where near as strong as the prepreg/baked original laminate. Its also hard to replicate the shape. The...

    Buying an old moth, a Bladerider. Mistake or not?

    Bungee in cockpit pulling bellcrank forward is a valid, more modern option. It needs a strong multi strand bungee as the lever arm is usually shorter. And make sure its still under good tension when the bell crank is pulled fully forward. Wand rake adjuster. The 3 points are the wand tip, the...

    Buying an old moth, a Bladerider. Mistake or not?

    Where is the May stick and bungee? That SS post poking forward from the wand mount should have a 125mm SS tube on it with a bungee stretched back to the wing. This is what pulls the wand down to the water and pulls the flap up when you are too high. I think you have the locking bolt set with...

    Buying an old moth, a Bladerider. Mistake or not?

    The old Mach2 wand in my shed is 1.4m long. I like to fly safe and low when it gets rough so I used to shorten it by up to 400mm.

    correct, Lengthen pushrod about 5mm at a time and make sure the wand is at maximum length.

    Buying an old moth, a Bladerider. Mistake or not?

    You should be able to find some used sails without the deck sweeper skirt to suit your rig. Just scan the moth classifieds and FB pages, they come up occasionally. All the newer production sails are deck sweepers designed for shorter masts and bent booms. You could use a deck decksweeper sail on...

    Australian Skiffs

    Also because the ratchet block works heaps better with the rope taking 3/4 of a turn than it does with 1/4 of a turn.

    1. The CB trailing edge damage needs to be fixed properly. Its a very high stress location, just below the hull. Its likely that the trailing edge bond is broken and the edge is split. This allows the board to twist which will make flying feel wobbly and very disconcerting. Also water will leak...

    Use a thinner slippery line for the wand and put some knobs on it where you grab it. One endless loop works best. Do not make it tight.

    Buying an old moth, a Bladerider. Mistake or not?

    That nut needs to be tight and needs to prevent any rotation between the linked components. Where you lock it up changes the rake of the wand at normal ride height. I think I used to have it at one extreme. Which ever end makes the wand well forward when at normal height (flap neutral). If yours...

    Buying an old moth, a Bladerider. Mistake or not?

    Foil care: Keep them assembled as every time you knock them apart you are wearing out the T joint and potentially making it sloppy. Just remove the tiller. Do not store them inside a vehicle parked in the sun even on a cooler day. It gets hotter than 30 inside, especially dark coloured...

    Buying an old moth, a Bladerider. Mistake or not?

    Black foils are mostly OK if the air temp is under 30 deg c. But even at that temp do not leave black foils in the sun for very long. Keep them I the covers and only put them into the boat just before launching. Mach2 fill the foils (V & H) with an expanding foam as part of the manufacturing...

    Buying an old moth, a Bladerider. Mistake or not?

    I have broken plenty of carbon extensions, bent plenty of aluminium ones but my plastic conduit ones last for ever.

    New Moth revealed

    Less vang releases the middle leach, not just the top. You still need tight middle leach for fine apparent wind angles and good unwind speed/height. Soft top flattens the top of the sail and lets the top release a little which gives better ability to steer around waves and gust response in top...
