Three years ago on our run back to the LI Sound from Block Island we were sailing in 12 knotts of wind in fog with visability of 1/2 mile. Out of the fog pops up the boomer. 9out of Groton I am sure) Scared the crap out of me. No sign of it on the radar of course. All elctronic instruments on the boat went haywire for 10 minutes.
Looks like one of the newer fast boats, no boomers out of Groton. I think that one of the last times you would have seen one was in the 90's as they decommissioned the Poseidon system. I had the pleasure of pulling into homeport a couple of times in the late 80's and we did see mucho traffic during transit....not fun.
