you dont necessarily need massive amounts of memory, unless you already have them, they can get expensive depending on size, a suggestion i would do is go get a Seagate 500G portable HDD and 1 or 2 (if you have 2 cameras) 8 or 16 GB memory cards, and each night after you are done shooting, download all photos to the HDD and wipe the cards clean... it will keep the cards working fast, and wont clutter your cameras with photos if you decide to flip through them... its a pain when you have 1-2000 photos on your cameras....

you might also, and i highly advise this, start buying your gear now while you are there... during years like this the stores in this state get hammered and alot run out of products... what i would suggest gear wise is this:

#3 and #4 Blue Fox spinners, in pink, red, blue, and yellow..

1.5 inch mini squid to put on the hooks below the spinners..

Buzz Bombs as said, pink, red, blue, white/pearl are good colors..

if there are no downriggers on that boat, you will need banana weights and Deep Six's or Dipsy Divers (this is if you seriously intend to troll deeper waters)

hooks, 1/0, 2/0, and 3/0 will be fine, spinners should use the Siwash hooks to keep the point from tweaking away from the body of the spinner as what happens with Octopus hooks and the bent eye.. but Octos are good to use under the Buzz Bombs (i do and have no problems with them)...

i have 1 rod i would be willing to loan you, if you pay a deposit of course, its a Lamiglas 8'6 10-25 3/8ths to 2 ounce with and Ambassaduer 5500 C3, the reel is kinda small for trolling per say, but it still can be done, if i decide to buy a line counter reel in June i will throw that on instead of the 5500... the 5500 is fine for casting towards jumpers with the BB's and Spinners...
