So why was he sitting on the high side?

Really? If the bridge clearance is 65 feet and the mast height is 80 feet, then the cosine of the heel angle would be 65 / 80. This corresponds to a heel angle of about 36 degrees; the mast is 54 degrees above the horizontal. Still, a pretty impressive maneuver.

If the bags are full of water, then his setup is self-limiting. As the bags start to immerse, the pull on the halyard is reduced. This means he would be nearly unable to capsize unless he winches the bags WAY too high. I think he has done this trick before.

I think the reason he is sitting on the high side is twofold: He can see the masthead more easily and it is more comfortable

The weight of one person really doesn't make much difference when you are trying to heel that big a boat that far.

If someone had to do this sort of trick a lot, would it be worth putting a small video camera on the top of the mainmast? This would make it easier to judge clearance.

God bless!

Sail on the outside, no wonder it's posted under "wimp''

Cool pic in so many ways. Like the near bridge. And the waterball we can see is not at the masthead.

If someone did this a lot, some yahoo in a pickup with a shotgun could empty those waterbags at the worst moment and drive off yahoo-ing about ruining some yot-snots day.

they must do it often.it looks like a port side extention is in place. to add buoyancy to the hull while in that position? that guy in the cock pit looks like he has the best seat in the house

It's likely that they have used the method numerous times transiting the ICW where there are quite a few bridges with 65' and lower clearance.

It usually doesn't work out too well.
