A Hole in the Water. The DREW NOLAN stories, #1

Vacationing with an old High School flame on his charter boat in the Caribbean, Nolan sets his hook into something he wishes he hadn't. The floating bag of stink hauls him into deeper and deeper waters until there's nowhere to go but down. Drew gets dragged from his home port in Key Largo to up the Florida Coast and into a crummy marina, then out to a posh resort on the island of Bimini, then across the Caribbean to the south Texas coast, then to a Colombian resort island where possibly, just possibly, the drug cartel won't notice him.
Introducing his girlfriend June, smart, sassy and sexy. There's his Rich-As-Croesus brother-in-law, Watt, and his poor as dirt first mate Wiley. As for people wanting his more than roughed up, there's the dapper lawyer for the drug lords, Lawrence, a mysterious and too all-knowing Ghost who keeps telling him to mind his own business, and more than enough people banging him on the head. There's Cordell Rapp, wannabee fishing king, gotta be smuggler, has to be killer whose partner it was that found himself on Captain Nolan's hook.
Oh yeah, let's not forget Charlotte Rapp, the woman with the champagne-colored hair. She's the weasel Rapp's svelte and abandoned wife who joins Captain Nolan for a cruise he won't soon forget.
