Built in GRP by US yard Westport to a design by Gregory C. Marshall, Relentless was delivered in 2005 as a Westport 130 model and most recently refitted and repainted in 2020. Accommodation is for up to ten guests in five cabins consisting of a full-beam master suite on the main deck, two VIP suites and two twins. In addition, the cabin configuration can be altered to suit all combinations of groups aboard.
Entrance to the main saloon is through double stainless steel and glass doors. There is a large L-shaped sofa to port with two occasional chairs and an ottoman. The saloon windows are very large, offering panoramic views while relaxing in front of the entertainment system, at the bar, or at the games table on the starboard side. The formal dining area is located in the forward part of the saloon and seats ten guests.
The main deck aft is the most spacious in its class, featuring a large round table for casual al fresco dining, an aft settee, occasional chairs and a functional service bar.
The upper deck aft features a large L-shaped settee and table to port, a built-in television screen and an overhead customised awning supported by carbon fibre poles. Going forward from the upper deck aft is the skylounge with large windows, an office, day head, wet bar, fireplace, L-shaped sofa and several occasional chairs.
Twin MTU 12V4000 M90 diesel engines give her a cruising speed of 21 knots, topping out at 24 knots.
