I agree that doing broad reaches is better than a straight downwind run, certainly a lot quicker.
I am using the AI as a work platform to monitor the Chichester seals and other wildlife from. Some of the places I need to get it are down very narrow often shallow creeks (maybe 3 AL lengths wide) and often the normal wind direction is straight down the middle, so requires the mainsail out as far as it will go to maximise the wind. Hence my thoughts towards a spinnaker pole.
Coming back up I have to Peddle / Paddle or do lots of very short quick tacks.
The Barber Hauler works fine to a point, but using a pole will get the sail right out past the Amas, it will create a bigger surface to catch the wind and hopefully work better.
I have got a couple of old assymetric spinnakers kicking about, maybe that might be the next mod? Problem is they are left over from my 59er and K6 and are way too big for this baby and would need cutting down.
With a spinnaker setup correctly, it should help lift the bow which would help with wave piercing. It would put excessive stress on the mast etc without some stays to help. Not sure the seals would be too impressed if I rock up at their mudbank with a sodding great spinnaker billowing and the bows 2 feet in air!
Hmmm. interesting thought though...
