Helios Junior / Junior III

The Helios Junior III is a robust double‐walled moulded polyethelene support tender boat. Compared to regular inflatable dinghy tenders, the Helios Junior III is extremely heavy‐duty, and can be operated in
very shallow waters, and even for beaching operations, without fear of puncture or cuts. She is extremely buoyant and can hold substantial loads with ease and safety. She has been carried to off‐shore trial sites for use as a tender to many underwater equipment sea trials, where she is lowered and recovered from the water with our mother ship, the OPL 22. She is the ideal boat for carrying out different forms of diving, survey, research, and logistics support operations in both deep and extremely shallow waters.
