2020 Tideline 365 Offshore

The 2020 Tideline 365 Offshore is a 36-foot fiberglass catamaran powered by twin Suzuki 350-horsepower outboard engines. The asymmetrical twin-hull design delivers stability and efficiency, with a shallow draft under two feet for flats access and a wide 11-foot beam that supports both offshore capability and family comfort. The tower folds down in approximately ten minutes, and a trailer is included.

The boat cruises at 30 knots with a 480-gallon fuel capacity that extends range significantly. Joystick control—available in Optimus 360 or Mercury systems—provides intuitive maneuvering. An electric windlass handles anchoring. The cockpit layout centers on serious fishability: twin 45-gallon pressurized livewells, two in-deck 88-gallon wells, and over 2,300 quarts of insulated fish storage across two 815-quart boxes and a 688-quart coffin box forward. The raised casting platform at the bow converts to chaise seating with removable backrests.

Forward accommodations include wide seating areas with integrated handrails and padded combing throughout. The helm features a broad, glare-free dash suitable for triple multifunction displays. Beneath-console volume houses battery banks, breakers, and electrical infrastructure, with space for optional fresh or dry-flush heads.

Construction uses hand-laid vinylester glass with foam coring and an aluminum-reinforced grid. Through-bolted backing plates and Gemlux hardware reinforce the build. All hatches are finished on both sides, gasketed, and equipped with overboard drains. The integrated transom bracket design keeps the aft cockpit open and uncluttered.
