Re: Downwind sailing on Amel 54 and storm jibs
There are many ways to use the single pole system. And nuances which make it work well or poorly on the 54. It is indeed a pig to set. To do it alone you need relatively calm seas. It is heavy and that’s the main issue, the mass produces significant tortional resistance to the axial movement of the ship. This loads the guys, and their attachment points significantly: usually the cleats. Using 4 down guys helps. I would also re-rig with dynamic lines as opposed to the very unforgiving dynema lines which come standard, reducing the jerks and high momentary loads of rolling.toggle quoted messageShow quoted text
However, once set, past the drama, the pole works well. Getting the angle right is critical for the shape of the Genoa, but too low and you risk dipping the tip in the ocean on a big roll. Even with a gybe the sail does not collapse. We can sail pole set to wind up to about 150 degrees. If you’re feeling lucky, you can set the pole to wind and then an asymmetric spinnaker on the Lee side. You go really fast in light winds.
The problem comes with fickle winds from the stern. Past that 150 degrees the sail cavitates and now you’re limited to a degree to reset the sail on the opposite side, the non pole side. Good to have a little extra length in the Genoa sheet.
Commonly that happens at night. In the rain. While your crew is asleep. So you change the boat angle to accommodate the wind, or turn on the motor, or suit up and go on deck in dangerous conditions. But this is the case with any single pole setup.
I suspect the dual pole gives a wider angle of potential sailing relative to those deep wind angles. I’m not unhappy with the single pole setup. At 50 in pretty good shape I deal with it. But it might be different at 65. Hopefully I have the chance to know!
