Jim, do you mean generically the aft main was still common, or that true aft main was/is allowed in the Laser?

Generically still common.
but I think a true centremain would have been a right pain in a Laser. Don't want to move sheet position for ergonomics, so would have needed loads of purchase which would be loads of friction with 1970s plain bearing blocks and the thick sheets we used when gloves were an unusual luxury.

5 out of 7 of my boats are aft main, which puts me firmly in the 70s!
I liked the upside down version the punk used, though I suspect there were friction issues. I can see it working well in a doublehander where you want to sheet centrally rather than to transom edge. |

None whatsoever, I sailed the Punk virtually every day for a month and didn't encounter any friction issues. Edited by sandgrounder - 03 Jul 16 at 4:00pm |

Glad to hear that. Why the D Zero not use it?
Was talking to someone at the club today who broke his shoulder a while back, and when he switched from Comet to Laser, discovered that he simply couldn't pull a mainsheet from that angle. He has converted his Laser to aft main. He hasn't tried it yet, but will report back! |

It is a pretty complex system and cost was an issue. The 3 pre-production boats had the facility to go for the sheeting that way. The production boats have a different deck mould which does not have the channel in the floor.

This thing about breaking Laser booms with centre sheeting.....on my 'modernised' Lightning I have a round boom instead of the old square girder one. This boom is made from an old Mirror mast. Yesterday was pretty windy, in fact I was pleased at my self for going out. Lightning booms are very long and the sail is Laser size but after three years my boom is not broken or bent. So, if centre sheeting a Laser on the existing boom is a problem just fit a Mirror mast! (No one will ever know).

I converted a Mirror mast into a Minisail boom, too. A bit heavy, but certainly strong!
Heavier that the Lightning Needlespar girder, I'd say, but more rounded for collisions with noggin. |

I know this is a very old, very long thread, but it’s a very hot day and I am bored.
I really enjoyed it from start to finish , made me feel very nostalgic for the range of contributors we used to have. Oh well things change . Hope everyone is well out there in forum land
