If I had the 4th boat I wouldn't need to tow any boat! lol
Ok when I did my 16km trial swim in lake ontario the water went from calm to 3-4ft swells I only had one boat (27ft) as the support boat, no kayaks or other support boats needed for the trial swim.
I only had a shortened crew of my wife and daughter (to time my feedings and pass me my food), my swim master, ( official from SSO watching my swim) his niece a second swim master in training and the Captain, at no time did i swim along side the boat except to get my feed, I did not swim behind the boat or along the wake, for the most part the boat was usually about 20-30ft to my right so I could see it and the crew to call me for my feedings, then I would swim up to the boat.
Would i do the swim without a support boat? without or with a wetsuit? No way! You need a boat for sighting and crew for feeding, they navigate and the swimmer follows along on the open water sighting off the boat. The only time on a Solo swim that you would have boats, usually zodiacs beside you is while you swim at night, then they are on both sides of the swimmer about 5 ft from you to keep you in sight.
Could you swim solo on open water swim with a life preserver,..I mean wetsuit? Yes, anyone can swim long with a PFD, er I mean a wetsuit! ;) but the challenge is to swim naked (no wetsuit) because when you get tired with a wetsuit, you can easly rest floating on the water at any time for as long as you want, but try treading water naked after swimming for hours on end? .
When I swam pulling my boat, the boat was my lifeline while in the middle of the lake if I got in trouble, unless I had a heart attack? lol I carried my feeding on the boat I pulled, which was all liquids attached to a line hanging over the side of the boat that I could reach while I swam tethered to the boat and I always had sight of the shore which made my swim possible, and of course no wetsuit used. But could this be done across a large body of water? probably, but i wouldn't recomend it because once you lose sight of land in the water swimming you have no Idea where you are or where you are going, With no land to sight you could be swimming in circles! thus the reason for the navigation boat with GPS to keep the swimmer on course.
My advice is to learn to swim open water without a PFD, er wetsuit, before attempting any solo swimming and do it safely with support! :)
"Which brings up an interesting discussion. Which of the following is more bad ass--swimming the 20 mile Catalina Channel (for example. Insert any of your favorite channels) either:
- No wetsuit, but with a navigation/feeding boat that will also block wind/chop and pull the swimmer in case of trouble. (ie: Catalina Channel Swimmer Federation rules); or,
- Wetsuit, but no boat at all for navigation/feeding/drafting/rescue. Entirely self-supported and solo.
I'm not concerned about which federations would sanction it: that's bureaucracy and ego. I want to discuss which is harder, and why no one does the latter."
