Unique Lounger Layout

The 851 Grandeur offers a unique lounger layout which doubles as a berth for overnighting.

Squabs are removable which provides access to a large under-seat storage compartment (large enough for golf clubs and more). The front squab is interchangeable with a forward-facing passenger seat for longer trips.

A starboard-side galley is standard in the Grandeur which offers a large bench, gas cooker (audited to comply with AS/NZS 5601) moulded sink, cupboards, drawer and fridge.

The Driver’s Seat also hinges forward to offer more bench space for meal preparation.

World-Class Hardtop

Two hardtop hatches introduce natural light and airflow into the cockpit area. These hatches are also useful for spotting work ups and offer brilliant ventilation for the 851 Grandeur’s mid-ship located food preparation and cooking facilities.

A 3-facet toughened glass windscreen with double mullion system for superior strength is standard, as are sliding side windows, stainless steel fore-aft rails and vertical port & starboard grab handles.

All Tristram hardtops are designed with moulded side and top flares for wind deflection. Ceilings are also lined with vinyl paneling for sound absorption.

A Fusion Bluetooth entertainment head unit and speakers are mounted in the hardtop’s instrument panel and each owner has the option of mounting their VHF beside the Fusion head unit or in the skipper’s moulded side pocket.

Fully moulded boarding platform. Seal-free to keep engine bay dry.

Moulded Boarding Platform

A seal-free boarding platform ensures the cockpit and engine bay remain dry and clean. Backing up in even the fiercest of seas is effortless thanks to the platform’s carefully designed height and fully moulded top and undersides.

A recessed boarding ladder, LED boarding lights and strategically placed stainless steel grab handles are offered as subtle practicalities to ensure your time on the water is stress free.

An optional multi-purpose stainless steel Transom U-Bar allows owners to further utilise their boarding platform by enabling the addition and removal of a baitboard, tender, auxiliary engine or bbq.

The dynamic and unique ‘Tristram’ look is created with moulded transom deck fins that roll down and onto the platform for an integrated and sleek look.
