36 Tideline 2020 Boat for Sale

36' Tideline 2020

2020 Tideline 365 Offshore — Quad-Powered Predator With the Soul of a Custom Sport-Fisher

When a 36-footer cracks 60 mph yet still softens a six-foot head sea, you know you’ve left ordinary center-consoles in the wake. This 2020 Tideline 365 Offshore marries Robert Ullberg’s custom-boat lines with an offshore catamaran’s two-point stance, then adds the brute force of quad Mercury 300 V-8s. The result: a bone-dry, razor-smooth ride that cruises close to 40 mph and tops out north of 60 mph while sipping fuel from her cavernous 480-gallon tanks — range and speed few 40-foot monohulls can match.

Performance & RideThe Tideline’s asymmetrical twin hulls track like rails and cushion landings so thoroughly that offshore runs feel like a bay-day joy-ride. Quad 300s push 1,200 hp through the 9,200-pound platform, keeping draft to just 18-20 inches for skinny-water access while delivering blue-water stability that rivals much larger boats.

Deck Layout Built for Battle and ComfortFrom the transom aft-facing mezzanine seats you step into a cockpit engineered for serious crews: twin 45-gallon pressurized livewells plus two in-deck 88-gallon wells mean you can carry pitch-baits, goggle-eyes, and sword baits without compromise. Two insulated 815-quart fish boxes flank a mammoth 688-quart coffin box forward, all macerated and ready to ice tournament totals. 

Helm & TechnologyA wide, glare-free dash swallows triple MFDs, while Optimus 360 or Mercury Joystick (your choice) makes the big cat dance into tight slips. Massive under-console volume hides batteries, breakers, and rigging in yacht-class order, leaving room for an electric head or dry-flush unit.

Forward Lounge & Family SpacesForward, a raised casting platform converts to chaise seating with removable backrests, and the coffin box lid doubles as a sun-lounger. Wide 11-foot beam and high freeboard keep kids secure; recessed handrails and padded combing bolster comfort from bow to stern. 

Construction HighlightsHand-laid vinylester glass, foam coring, and an aluminum-reinforced grid give the 365 a monolithic feel, while integrated transom brackets free up the entire aft cockpit. Every hatch is finished on both sides, gasketed, and drains overboard; Gemlux hardware and through-bolted backing plates speak to the brand’s Carolina-custom DNA. 

Why This Tideline 365 Stands Out

• Quad 300 hp package — the fastest, most maneuverable setup available on a 36-foot cat.

• 480 gal fuel + catamaran efficiency = canyon range without auxiliary bladders. 

• Over 2,300 quarts of insulated fish capacity — bring the whole tournament home.

• Twin 45-gal and twin 88-gal livewells plus optional tuna tubes keep every bait alive and separated.

• Draft under two feet lets you slide across the flats or nose onto the beach after chasing sails offshore.

This 2020 Tideline 365 Offshore with quad 300s is equal parts missile and mothership: built to punch through confused inlets at dawn, sprint 60 miles to the bite, and still bring the family on an evening sandbar picnic in comfort. If you’re searching for a listing that checks speed, fishability, and family credentials in one turn-key package, your next ride is waiting on this deck.
