Fichy, Nantucket surf fishing has a big problem right now: seals!
Last year's fall trip was totally a bust because of them (and the torrential rains didn't help either). Don't know if late spring (June) is any better in that regards as haven't been out there at that time in 4-5 years. Those fkers would follow the truck up the beach! Couldn't catch more than 1 fish before they found you and would steal everyone thereafter. Next time I pack the 30-06 or some m-80s.
Anyways, when you are ready to go I could pass along some tips.

I've had some horrible experiences with horseheads and greys. The mouth of the Merrimack gets loaded with them, they f'in ruined an early May trip for me, and have scared the sheet out of me night fishing. The most frustrating for me may have been at the mouth of the Saco and Scarborough rivers in Maine. I had gone out on a minus tide at least a 1/4 mile out on the mud  flats to reach what i figured would be a great concentration of fish in the channel. i got out there, made one cast and hooked up on a good fish. I got it taken care of, looked up to find the  area now  dotted with evil little seal heads.  Long walk for one fish and done. I don't mind the sharks coming in closer. Let 'em eat! 

Have had much success on strip in strikes. Green machines or smurfs tied with either spun deer hair or chennille (chenille better for cold months) and white calf tail... Nymphs and wets on either mid drift or straight down stream retrieval... And yes... Even the infamous estaz... And yes even in black!!!

Not a dumb question at all. Any DEC officer in their right mind will no your intent if you're stripping in

I thought a little about it and have come to a partial  conclusion why I've seen no one doing it. If you have a bunch of weight on to dead drift, you increase your chances of hanging up  markedly by lowering the rod tip and stripping. That knocks about 80-90 percent out of the box, right there. In defense of some, eggs and flesh don't swim or twitch. Others are swinging and getting movement via the swing and feel the extra movement isn't needed or wanted.  5% to cover that group? The other 5-10% has never seen anyone else do it so it must be wrong. I guess I fall in that category. 

Might have to pull out a deceiver tomorrow and strip away. 😀

Fichy, give it some time... Now that its mentioned on the internet, give it about 3 years and its all anyone will be doing and talking about :)
