Exceptional Speed, Range & Stability

Meet the 2020 Tideline 365 Offshore, a high-performance power catamaran built for those who want speed, offshore capability, and serious fishing performance without giving up comfort. Powered by twin Suzuki DF350s delivering 700 HP, she combines an incredibly stable catamaran ride with impressive range, a shallow draft, massive fishing capacity, and a tower that folds down in less than 10 minutes—making her just as versatile for offshore adventures as she is for family days on the water.

THE EXPERIENCE

This is a boat for someone who doesn't want to choose between serious offshore capability and having fun on the water with family and friends.

For the serious angler, the cockpit is built to fish. There are twin 45-gallon pressurized livewells, two 88-gallon in-deck wells, two massive 815-quart insulated fish boxes, and a 688-quart forward coffin box. There is room for the gear, bait, and catch that come with a serious offshore day.

But walk forward and the personality of the boat changes. The raised casting platform converts into comfortable chaise seating, the coffin box becomes a forward sun lounger, and the custom curtains and sun shades make it much easier to turn a fishing trip into a full day on the water.

This is a boat for the buyer who fishes hard but doesn't want a boat that can only fish.

She can be a tournament platform in the morning, a comfortable family boat in the afternoon, and a sandbar boat at the end of the day.

BROKER INSIGHT

Tideline is known by serious fishermen, and this one is even better with its collapsible tower and trailerability. The non-stepped hull is a great advantage when the weather turns sour and you need to get home. The twin Suzukis are very efficient, getting on plane in less than three seconds with virtually zero bow rise. She's a beast!
