Welcome to the club - congrats on your initial success.
1. Whistle attached to my PFD
3. Compass & or PFD
4. A pump is worth it's weight in gold
5. Spray skirt
The hard part is trying to fit in the necessities for fishing.
Spin rods & rubber make it an easy job
I'm down to one fly box, one spool of tippet material & a spool of wire.
Good luck - let me know if you're going to be in the Pocasset area & we can pull a sunset cruise.
