We sailed overnight from Cuttyhunk to Edgecomb Maine.
Crossing the Stellwagon we saw lots of whales which were great. Then near dinner time, I spotted two fins each about 24" out of the water which I thought were 2 giant sun fish close to each other. I turned the boat around to come nearer.

It was a huge shark!

He came up along the boat within 15 feet. and from the dorsal to the tail was 10 to 12 feet. He then just swam off.

Then he turned and came right for the boat at a high rate of speed. Just before hitting the boat, he made a right angle turn and stopped. At speed I could tell from his bow wave that his dorsal was about mid length making him 20 feet plus. We jumped to the middle of the cockpit thinking only of Jaws.

Then we noticed a second one on the other side of the boat about 100 yards away.

As usual, we tethered in when on night watch, but this time with an added reason not to go overboard. I was shaking for hours.
