When it comes to fishing boats, there are definitely two styles that correspond to the two basic styles of fishing. On the east coast it's all about day trips and mostly trolling dead bait, so the boats tend to be more conventional-looking, faster, and with average fuel capacity. Since it's rare for these boats to anchor or for anyone to go forward of the cockpit other than to tie up at the dock, the "look" is to eliminate bow pulpits and bowrails for a sleeker line.
On the west coast, the crews will pull a spread of lures but they spend all day up high scanning for marlin on the surface with gyro-stabilized binoculars--when they see a fish, a crewman goes up to the bow and pitches a live bait to the marlin. These boats are also set up for long-range trips (think SoCal to Cabo, Mag Bay, East Cape, etc.) so they tend to be much slower but with a ton of fuel capacity, not to mention huge livewells. They usually have wraparound bow rails and forward livewells to facilitate a crewmember going forward to pitch to a fish, and since there are few marinas along the way, these boats usually have more in the way of amenities for the crew, who may be aboard for a couple weeks at a time.
I grew up marlin fishing on the East Coast but I've done plenty of the West Coast stuff too--as they say in Cali, it's, like, a totally different world maaan. |
