How long is your pole?

'm currently shopping for a whisker pole and am curious if there is a standard formula for what length to buy? I need the pole for a 145% genny on a rig with demensions of J-14, I-41, P-35.

Mine's telescopic, going from J to 1.5xJ in three steps.

Mine is telescopic as well - responds by extending to it's full length when needed.

TB mistyped his response... I believe he meant to say microscopic.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I'd post a photo of my pole SD, but it wouldn't fit on your 32" monitor without scrolling.

T, with a J of 14 feet, the genoa having 145% over will be at 20.3 feet from the bow.

For a pole you need 15 feet max. That will alllow a sail angle of 90 degrees from the mast.

You do not need more than 15 feet according to my calculation. Get and expanndable one but do not exceed 15 feet.

Alex, a 25 ft pole would hold a 145% 14 ft J out at 90 degrees to the centre line. That would present the whole genoa area on a run. So how about 20 ft of pole?

My pole is also telescopic. My J measurement is 14' but my pole goes much longer than 15'. If the sail (150 genny) is being flown farther forward than Giu's measurement then 15' will not be long enough. I think Giu is assuming that the sail LP is the hypotenuse. I would buy the pole with a length so that the pole can be the hypotenuse. That would make the max length you need somewhere around 25'. That is probably a bit long, but I think 15' is too short for a whisker pole on a boat with a 14' J. 15' is probably right for a spin pole.

There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
