Boy, I'm with you on that, Jim. I've done the about half the WW in a sea kayak. It is prettier then you might think. I've also done Nightmare 2-3 times in a sea kayak with friends. It was fun and not particularly difficult. BUT, doing Nightmare in an AI would take ALL of the fun out of it. Why, why, why would you do that? But, we each like to take the less travelled path. Maybe that is the explanation.
BTW, Paul, I've had an alligator jump at least 3 feet out of the water. He was about 20' away, and I don't know why he did it. He was submerged & I didn't see him until he jumped. Jump or simply climb up on an AI or Tandem would be no problem for an alligator or croc. I've never heard of such behavior--that is the one comfort, perhaps.
Since I built and started to use hakas, it just seems my AI does not deep-dive submarine as much. Yes, water flows over the bow & front hatch, but it just does not seem to dive as deeply. Perhaps, because I put the heavier weight on the windward haka, the boat is running flatter and that makes the difference. And, perhaps, I'm just not traveling as fast.
Since I began to use hakas, I am much more conscious of weight. My hakas weigh a total of a little over 22#. I no longer carry my table (use 1 haka) and that saves me 5#--still have a haka deficit of 17#. Water & water containers are a huge weight on a 6-7 day trip. Then, there is my cooler--it weighs 11# empty. When my wife travels with me, we can share some of this weight; but solo, it is too much. Getting rid of my cooler would get my haka deficit down to 6#.
Water containers can be a significant weight. Hard-walled plastic bottles, like the Hobie bottle, weigh 6-7 oz, and only carry a liter. A 10 liter Dromedary bag, which is not bothered by raccoons or rats, only weighs 9 oz.
Just random thoughts.
PS I'm sure Hobie's Penguin Man & Ocean Diva will be there in a tandem w/ jib.
