“Knot Behavin'” — 2000 Sea Ray 380 SundancerLifetime Freshwater · 784 Hours · Fully Modernized Raymarine Axiom+ Electronics Suite

Overview

“Knot Behavin'” is a lifetime freshwater 380 Sundancer that has been comprehensively re-equipped from the helm out. In 2021 and 2022 the current owner invested in a complete Raymarine Axiom+ navigation refit, a thermal night-vision and safety package rarely seen on a boat this size, a full Fusion Apollo audio system, a lithium house bank, and a new Sunbrella camper-top enclosure.

The result is a classic Sea Ray express cruiser layout — two private sleeping areas, full galley, enclosed head with separate shower, and a large entertaining cockpit — paired with electronics and safety systems that would be at home on a boat three times the price. Original MerCruiser gasoline engines with approximately 784 hours, both running strong with no known deficiencies. Westerbeke 7kW generator runs strong and carries the entire boat at anchor or underway.

Four seasons of Lake Ontario cruising and consistently maintained. Never in salt water.

Hauled and stored indoors every single winter in a fully enclosed barn at the marina — not shrink-wrapped in a yard. Combined with a lifetime freshwater history, that is why the hull, gelcoat, canvas and brightwork present the way they do on a boat of this age. No known blistering.

Navigation & Helm Electronics (2021)

• Raymarine Axiom+ 12″ multifunction display (helm)

• Two Raymarine Axiom+ 7″ multifunction displays

• Raymarine Quantum 2 18″ solid-state CHIRP pulse-compression radar with Doppler collision avoidance

• Raymarine AIS700 Class B AIS transceiver with antenna splitter

• Raymarine EV-150 autopilot with p70Rs color control head — new EV-1 sensor core installed and calibrated 2026

• Raymarine DST810 smart ultrasonic thru-hull — depth / speed / temperature

• Raymarine Ray63 dual-station VHF with integrated GPS (helm and cockpit)

• Raymarine SR200 InfoLINK SiriusXM receiver — live satellite weather overlaid directly on the plotters, no cellular coverage required

• Fox Marine MEFI-3 engine gateway — full engine data displayed on the Axiom plotters

• Raymarine HS5 SeaTalk high-speed network switches

• Raymarine YachtSense Link marine mobile router

All three displays are networked, so radar, thermal video, chart, sonar, engine data and weather can be called up at any station.

Thermal Night Vision & Safety — The Standout Feature

This is what sets “Knot Behavin'” apart from every other 380 on the market.

FLIR M232 pan-and-tilt marine thermal camera feeds live thermal video to any or all three Axiom+ displays. On the 12″ screen the image quality is exceptional. In total darkness it reveals unlit boats, floating debris, deadheads, channel markers, shoreline and — critically — people in the water. The camera detects objects both above and below the surface for genuine 360-degree situational awareness after sunset.

The M232 also integrates with the plotters’ Man Overboard function: trigger MOB and the camera slews to the target and actively tracks the person in the water while the rescue is carried out. Very few boats in this size range have this capability.

Paired with Doppler radar sensitive enough to paint birds on the water, plus Class B AIS transmit and receive, this boat offers a level of low-visibility and night-running confidence that is genuinely rare in a 38-foot express cruiser.

FLIR AX8 thermal imaging camera is permanently mounted in the engine bay for continuous condition and temperature monitoring — early warning on exhaust, belt, and bearing temperatures before a problem becomes a casualty.

Audio System (2021)

A serious, properly engineered Fusion Apollo system — not an afterthought.

• Fusion MS-RA770 Apollo touchscreen AM/FM/Bluetooth head unit (salon)

• Fusion MS-SRX400 Apollo zone stereo (cockpit)

• Fusion SG-DA41400 four-channel amplifier

• Fusion Signature Series 3 10″ marine subwoofer, sports chrome

• Fusion Signature Series 3 SG-FL652SPC 6.5″ marine speakers with CRGBW LED lighting

• SiriusXM antenna installed and ready for activation

Output is more than enough to enjoy music clearly while underway. The Apollo platform also supports party-mode linking with other Fusion-equipped boats — a real asset when rafted up at the sandbar.

Electrical & Power (2022)

• Four Banshee 100Ah 12V LiFePO4 deep-cycle house batteries with integrated BMS — 400Ah of lithium capacity

• Victron Energy Orion-Tr Smart 12/12V 30A DC-DC charger with Bluetooth monitoring

• Lifeline GPL-2700T generator starting battery

• Westerbeke 7kW generator — runs the entire boat at anchor or underway

Comfort, Canvas & Cockpit

• Sunbrella camper-top canvas enclosure (new 2021) — bright, vibrant blue with no fading; Strataglass is clear and uncoloured with no crazing or clouding. Extends the cockpit into fully usable living space in cool or wet weather

• Air conditioning and heat in both the salon and forward stateroom — both units run strong with no known issues

• Trim tabs — operate perfectly

• Electric windlass — operates perfectly

• Original interior in excellent condition — upholstery is free of tears, burns and staining. Cherry laminate joinery throughout, clean and unmarked.

• Original forward bow cushion included — the one piece almost always missing on a 380 of this vintage.

• Nova Kool R1200 1.2 cu ft AC/DC cockpit refrigerator

• Magma Catalina infrared gas grill, swim platform mounted, easily removable

• Two 24″ LED televisions — salon and forward stateroom

• Tri-color LED cockpit lighting

• Rocna Vulcan 22kg galvanized anchor with 100’+ of chain

• Gray water holding tank — an uncommon and desirable factory option on this model. Currently bypassed; easily reconnected.

Included Extras

Fenders, dock lines, life jackets, shore power cables, and additional gear convey with the boat — the new owner can cruise the day they take delivery.

Service History

• 2021 — major professional tune-up on both MerCruiser engines, $1,700 (receipt available). A noticeable improvement in how both engines run.

• Oil and filter changes performed on schedule by the owner since.

• No known mechanical concerns on either engine or the Westerbeke generator.

Known Conditions — Sold As-Is

The owner would rather a buyer hear this up front than find it on survey. Nothing here is a project:

• Shower door needs adjustment to close fully.

• Salon sink drains slowly. Long-standing, no other symptoms.

• Fuel gauges fluctuate under power. Both gauges began doing this at the same time in 2022, which rules out the sending units — almost certainly a shared ground or common feed at the helm. Not chased down.

• Bottom paint was last applied in 2020 by the previous owner; no records convey. It is due for a coat. Sold as-is.

The Bottom Line

Freshwater-only history, moderate hours on strong original engines, and roughly $30k of upgrades including Raymarine, FLIR, Fusion and lithium-power investment already done and sorted out. The hard, expensive, time-consuming part of owning a 25-year-old express cruiser — bringing the systems into the modern era — has already been paid for.
