A long-range blue water game fishing trailer boat from Tristram Marine. Available in sterndrive, single outboard or twin outboard.

Class-Leading Beam

With an impressive 2.78m beam, the 821 Offshore delivers exceptional stability and confidence in all conditions — whether underway offshore, at rest, or entertaining family and friends. The generous beam creates a noticeably larger, more usable deck space, enhancing comfort, fishability, and ease of movement throughout your boat.

Wide side decks provide safe, easy access to the foredeck, while the optional non-skid finish transforms the bow into a practical elevated casting platform for serious anglers. The result is a hull that combines true offshore capability with the space, balance, and versatility typically found in much larger boats.

Digital Glass Dash

The optional one-piece glass helm fascia delivers a striking, ultra-modern command centre designed to elevate both form and function at the helm. Featuring twin 12″ Simrad MFD displays seamlessly integrated into a single clean glass panel, the system offers exceptional visibility, intuitive control, and a premium automotive-inspired finish rarely seen in offshore trailer boats.

A first-of-its-kind offering from any manufacturer in New Zealand or Australia, the Digital Glass Dash sets a new benchmark for helm design and onboard technology integration. For owners seeking tailored electronics packages, a range of alternative Simrad and Garmin configurations are also available to suit individual preferences and fishing styles.

Diverse Cockpit

Meticulously designed for versatility, the 821 Offshore’s cockpit adapts effortlessly to every style of boating — from serious offshore gamefishing missions and extended overnight stays to relaxed raft-ups and entertaining on the water. Spacious, intelligently configured, and exceptionally well-appointed, the cockpit balances premium comfort with practical functionality in every detail.

Generous usable space, thoughtful storage solutions, and flexible seating arrangements create an environment equally suited to hardcore anglers, cruising families, and social occasions alike. Whether chasing record-setting fish offshore, unwinding at anchor, or hosting friends for the afternoon, the 821 Offshore delivers a refined onboard experience designed to make every outing memorable.

Underfloor Rod Storage

Exclusive to the 821 Offshore, the innovative underfloor rod storage system has been designed to maximise both practicality and onboard versatility. Twin 3m-long storage lockers provide secure, out-of-the-way accommodation for game rods, soft-bait setups, and long tackle, helping keep the cockpit clear and organised while underway.

Each locker can be optioned with integrated LED lighting and an in-situ washer jet system for effortless washdown and improved visibility in low-light conditions. Beyond rod storage, the compartments also double as additional insulated fish kill tanks when extra capacity is needed, perfectly complementing the central underfloor bin during serious fishing missions.

For added security and peace of mind, a lockable upgrade is also available.

Built-In Tuna Tubes

Integrated tuna tubes are available on the 821 Offshore and are seamlessly incorporated into the diesel transom design for a clean, highly functional gamefishing setup. Engineered for serious offshore anglers, the system is designed to keep live baits in peak condition and ready for action when targeting pelagic species.

Owners can choose between two or four tuna tubes depending on their fishing style and bait requirements, allowing the vessel to be tailored for everything from casual live-baiting through to dedicated bluewater competitions. The result is a premium, purpose-built solution that enhances both fishability and cockpit integration without compromising space or aesthetics.

70 Litre Live Bait Tank

A large 70-litre live bait tank is seamlessly moulded into the transom on both sterndrive and outboard configurations, combining practical fishability with premium finishing details. Designed to keep bait healthy and active throughout the day, the tank offers generous capacity for extended offshore sessions and serious gamefishing applications.

A curved acrylic viewing panel creates a clean, modern appearance and features a precision-routered ‘Tristram’ logo for a distinctive finishing touch. Optional blue tank lighting further enhances visibility and adds a striking premium aesthetic to the cockpit, particularly during low-light or overnight fishing conditions.

Pull-Out 72 Litre Ice Box

A generous 72-litre pull-out ice box provides valuable additional cold storage while maximising cockpit functionality and space efficiency onboard the 821 Offshore. Cleverly housed beneath the aft port seating, the unit remains easily accessible while keeping the cockpit uncluttered during long days on the water.

Designed with versatility in mind, the ice box also doubles as a practical footrest for passengers seated facing the transom, enhancing comfort and usability in the social cockpit area.

For owners planning overnight trips or extended adventures offshore, an optional Dometic electric pull-out fridge upgrade is available, delivering increased refrigeration capacity and the convenience of onboard powered cooling.

Pull-Out Galley

In keeping with Tristram Marine’s philosophy of ‘cockpit-based cooking’, the 821 Offshore features a cleverly integrated pull-out galley designed to maximise practicality without compromising cockpit space. Positioned above the ice box, the galley incorporates a sink and cooker within a compact, easily accessible module, allowing owners to prepare meals comfortably while remaining connected to the social cockpit environment.

To further enhance functionality, the passenger seat folds upward to create a dedicated food preparation station — equally suited as a practical lure rigging station when the galley is tucked away. The result is a highly versatile layout that transitions effortlessly between entertaining, cruising, and serious offshore fishing.

Configurable Layout

The 821 Offshore’s configurable port-side seating has been designed to deliver exceptional versatility, seamlessly adapting from offshore fishing platform to premium social entertainer. Accommodating up to three passengers, the layout offers both forward and rear-facing seating configurations to suit cruising, entertaining, or relaxing at anchor.

By folding the backrests away from one another, the seating transforms into a social face-to-face arrangement, creating an inviting space for conversation, dining, or entertaining onboard. An optional side-mounted table further enhances the area, providing a practical and stylish setting for meals, drinks, or entertaining family and friends.

When lowered, the table also serves as the foundation for the optional infill squab, converting the entire port-side seating area into a spacious lounger ideal for relaxing in comfort between destinations.

Engine Control Moulding

The 821 Offshore’s ergonomically designed engine control moulding delivers a clean, functional helm layout with skipper comfort at the forefront. The console-mounted binnacle control is seamlessly integrated into a dedicated moulded pocket, placing engine controls naturally within reach for precise, effortless operation underway.

Thoughtfully designed to enhance both usability and aesthetics, the moulding also provides space for optional Simrad or Garmin remote controls, keeping key systems centrally positioned and easily accessible from the helm. A sculpted integrated armrest further improves comfort and support during long runs offshore, helping reduce fatigue while maintaining confident control in all conditions.

Designed in-house by Tristram Marine’s CAD Team. An exemplary combination of performance, ride, practicality and sharp flowing lines. The ‘pinnacle of premium’.
