Not really - they have an upper body harness that takes the weight when hiking flopped over the side. A sort of trap I suppose ... Rick |

The further up the mast the larger the radius in which you swing so the lest likely you get dunked when you come in! There gets a point where additional height does not really help as the 1m swing already is effectivly a straight line. I suppose if its too high there would be little inward force thus you would struggle to stay on the side of the boat. |

The other advantage of high trap mounting points is that you can move aft with less change of body-height/ force pulling you forward. Contenders seem to have such short wires I'm always surprised to see they can get back at all without facing entirely forward to resist the pull in that direction, but they do. How do you manage it, Contender boys (and BNS)?

How about this, If you hung the trap off the spreaders that would be the same as trapezing from the mast head. If you attached the trap wire to a cross piece 6' wide and fixed at the hounds would that give the same leverage as hanging from a very tall mast? Now then, if you make that cross piece swivel round the mast then when tacking you could launch your self backwards and fly round the back of the main coming to rest on the other side! Come on Cherubs you can do it. Just imagine the sight of a big fleet tacking round a mark with all the crews flying through the air.......like a chairoplane.

I guess it's quite a tall mast with a lot of rake. My trapeze wires come straight down and must be more than a metre behind the mast heel. On most Contender rigs the trapeze wire is crimped onto the shroud this has 2 advantages: slows down an inversion if you capsize because there is less holes in the mast (important with a boat whoes hull floats so high on it's side) and also means the trapeze make little difference to the sideways mast bend because it's acting on the hounds (important for such a whippy mast). The only downside of this (although I don't think the trapeze position is important) is that if you're lardy you need loads of rig tension. Otherwise when you go out on the wire in marginal conditions it reduces the tension in the windward shroud allowing the mast to bend off and depower - which means you have to come back in off the wire again!

As Calum says, 505's have tweakers on the wires to stiffen up the top of the mast down wind but its pulled in when going up wind so the mast doesn't invert. Most skiff masts are designed to be very flexible in the top section to let the main depower, you would lose this with a high trap point. It's not too much of a problem to pull an extra rope at the windward and leeward marks, especially for Jim and Donald when they're so far ahead ![]() |
