Dennis Blue Shark Fishing Charters

From doormat Fluke in Nantucket Shoals to Halibut east of Chatham to Cultivator Shoals to White Marlin south on Martha’s Vineyard to giant Bluefin Tuna and groundfish, the captain has all your offshore needs covered. His fast rugged seaworthy boat will provide more fishing and less running time.

This full-day trip gives you enough time to head out offshore in the pursuit of those big game fish, such as strong Bluefin Tuna or aggressive Blue Shark. The hunt depends on the season, so you may also be after Striped Bass, Cod, or Bluefish. Bring your snacks and drinks, everything else is provided.

This action-packed trip is a favorite among serious anglers. It runs 8–10 hours, depending on how hot the bite is. We’ll start by catching fresh bait, then head out and set the chum slick. That’s when the real fun begins—targeting Thresher, Mako, Blue, and Porbeagle sharks. We might even get the chance to watch a shark grab the bait boatside, up close and personal.

This trip is perfect if you're looking to get some extra fishing done before turning in. You'll target mainly Striped Bass and Bluefish, though you may come across other species. Customers are advised to bring sunscreen, polarized sunglasses, and adequate clothing. The trip can start at 6,7 or 8 AM depending on your preference and arrangement with the captain. Please note that, due to rising fuel costs, a fuel surcharge may be imposed.

That extra hour on the water could be the key to some real trophies on this 5-hour trip which is perfect for children and families.
