Traditionally, dive support vessels have been either RIB designs or converted workboats. The new Seawind Marine vessels have been designed with offshore working and its safety requirements as fundamental considerations..

All gas cylinders are integral to the vessel and out of sight, safely installed within the hull structure, but able to be removed with little effort to inspect and maintain. This also greatly improves the working area of the deck, and does not impede the dive team's activities. The wheel house design allows for good 360° visibility, with its oversized steel framed windows and the added eyebrow window arrangements to increase visibility when discharging or returning to the mother ship.

The topside of the wheelhouse has a superstructure arrangement which allows for all common types of quick release hooks to be mounted. The vessels have been specified to be as light as possible, requiring little or no alterations to the existing mother ship lifting equipment. Based on a weight of only five tons, this requirement was achieved comfortably.

The vessels are completed with a purpose designed 'A' frame arrangement that incorporates a self-righting safety system and integral dive ladder. The ladder, complete with hand grab rails, has been designed to be a permanent fixture, with a hinged system to allow safe access to and from the working platform.

Wheelhouse instrumentation includes a Furuno 1712 radar system, Icom VHF 1C -M421 marine transceiver with built in class D DSC, Icom UHF 1C-F610 marine transceiver and a Danforth A154 compass.
