Sonar manufacturer WASSP has developed a remote mapping system which provides real-time seafloor topographies to captains on the bridge from a tender scanning unknown waters ahead.

The WASSP-Wireless has been designed to address one of superyacht captains biggest concerns; underwater obstacle avoidance where hull damage or grounding the vessel is to be avoided at all costs.

Ideally suited to use when navigating in unknown waters or where marine charts lack sufficient detail, WASSP-Wireless is installed in the tender or support vessel of a superyacht and uses a wifi radio link to send a real-time seafloor map back to the bridge for display on a MaxSea navigation plotting platform. The system can either be bridge-integrated or run off a laptop with MaxSea software.

WASSP’s wide angle, multi beam transducer uses 112 sonar beams to render 2D or 3D real-time image on the bridge; a single pass at 20m depths returns a swath 60m wide. Seafloor topography, rock or coral outcrops and obstacles are clearly identified giving large vessels the opportunity to navigate safely into or through areas that would have previously been off limits.

WASSP Managing Director, Gareth Hodson says the system’s ease of installation makes it the perfect application for large luxury vessels.

“Unlike other avoidance systems, the transducer is mounted in the hull of the tender, thereby avoiding the need to slip and engineer transducer hull penetrations on the superyacht - usually an exercise superyacht owners like to avoid,” says Hodson.

“Alternatively for ‘rapid deployment’ the transducer can be pole mounted to the side of a tender.”
