I almost forgot — I’m be contributing another chapter to Dennis Zambrotta’s followup to “Surfcasting Around The Block.” It will be a brief chapter on what you need gear-wise to fly fish the island. Of course I’ll have my own opinions, but my goal, as always, is to help you get the most out of your fishing experience. I believe Dennis is hoping for a late fall publish date.

Where I fish on Cape Cod a sinking line is a must. 400 grain does the trick. I watch as Tourist
Anglers arrive with their intermediate fly lines getting skunked. I the fly shops tend to sell a lot
of those lines. Bill
Hi Bill, my arsenal includes a floating line and a full sinker. As always, you should fish the way you like best with the line that gets the job done.
