I've been sharking 2X, once with Capt Tom (  
let's go sharkfishing ) who's website is a treasure trove of information.  The only shark I've caught is an 8' blue.  Plan to keep yourself occupied bottom fishing which really made a success of the  Capt Tom trip, bringing home several 100's of lbs of cod/haddock while waiting all day for the blues to appear.  They (10-12' ers) finally did at the end of the day but only inspected, not injested, our blue fish bait. 
Oh yea:  what MrHunters said is what we did.
