Bobby go to the NMFS web site and look up - Guide for compling with the Atlantic tunas, swordfish, sharks, and billfish regulations dated Oct. 2007.
www.noaa.gov/sfa/hms/brochures/2007/october when you get to the brochure go to page 41 Q6 reads: Under regulation 50cfr635.21, a person must release a billfish caught by a hook or by using a dehooking device without removing the fish from the water. This paragragh is specifically in reference to billfishing. Since most tourment regulations have language regarding all state and federal regulations must be complied with the act of boating a fish is not the problem it is the act of putting it back if it does not meet minimum length that can be grounds for protest or DQ. This could be a problem with white marlin since in the MA500 a 66" white has weight anywhere from 49lb to over 70lb's. [ see the science page on the MA500 web site.] This should get interesting. Stay tuned.
