Off topic I know but Rogerd.... do you sail a plank? The nationals didn't seem to have any planks sailing (am I wrong?). It could be faster, right? What's it like compared to the trap?

ok, maybe you are right, i admit the osprey sailers a kielder are very good, and come to think of it, the design of the boat does suit the conditions that we experiance up here a little better than the skiffs (not blaming weather on our losses here - just an observation.

I was watching Simon Allen on his canoe at the weekend (Hoo Freezer). A brilliant hiking technique, his bum was over the end of the plank and his feet were easily over half a metre from the gunwhale of his boat - giving him catamaran like righting forces - way more than could be achieved with a trapeze. Have you seen those boats go on a close reach?

Sounds a bit like what would happen if you trapezed of a wing ... except you are not as mobile. Rick |

And you haven't got the leeward side of the wing hitting the water and slowing you down, or causing wav e drag and aerodynamic drag. |

And you can sit in the halfway position without wrecking your knees, leaving your arm more energy to gesiculate at the trap boats you pass.

Bumble, The plank is on a very old 1953 boat . At Netley open there were two plankers both of similar age. They are not competetive with the modern Hornets partly because they have a slightly different hull shape and on my boat I darent wind up the tension to high. Also the palnk is significantly heavier than a trap and fore and aft trim is very difficult. I sail the planker for fun and it is a great talking point on the beach. It is also rather frail so we have graded up to see if we can keep up with the fleet and now we have no excuse and we cant blame the boat.

There's a twin-plank class called the Skate in Australia that tried to allow traps and racks. They set the rack width so the centre of gravity was theoretically in the same place on the trap and rack boat as it was on the plank boat (where the skipper has a short plank and the forward hand has a 10 footer). Apparently the rack and trap boats were uncompetitive until the width was increased once more. I assume the reason is the drag of the lower rack and the fact that the weight of the plank adds weight on the right side of the boat. That's the reason the guy who owns the fastest small course-racing sailboat (C Class Cogito) is also a fan of planks. They're not necessarily better than wires, but they certainly have their advantages. |
