The Scan4Pipes Boats has been designed, with the support of Naval Architects with a ‘Vee’ shaped hull to ensure that its shape is optimised for manoeuvrability and minimal air entrainment beneath the sensors.
The boat’s design ensures that the natural velocity profile of the river at the sensor location is minimally impacted by the presence of the boat and that there is no flow disturbance from the hull apparent in the sensor data. The design also limits the passage of entrained air beneath the profiler.
If air bubbles pass beneath the Transmitter or the SBP, data will be lost. The boat is fabricated from Glass Reinforced Plastic (GRP), which provides a strong lightweight structure with stiffening ribs inside the hull. The GRP hull can withstand minor knocks and bumps and will not deteriorate under UV light. The boat is manufactured in two sections (i.e. with a removable bow), each having a separate hull and deck which have been bonded together.
The removable bow makes it possible to carry the boat in the back of a small - medium sized car and allows ready replacement of the bow in the event of severe front-end impact damage.
Grab handles have been fitted to the upper deck for retrieval and carrying the boats.
During manufacture, fixing locations have been molded into the hull for propeller shrouds and rudder supports, along with mounting locations for the motors and electronics.
The boat also incorporates protective strips down the sides and along the keel, and low-drag skids, to prevent damage when launching or berthing up against river/lake walls etc.
All metal components used in the design of the boat are fabricated using either stainless steel or aluminum. Many of these design features recognize that it is often necessary to launch and recover the boats at locations where access to the river/lake is poor. The boat’s design is therefore well suited to two-man deployment from a range of riverbank types. By way of example, it is quite common to need to launch from concrete walls some 1-3 feet above water level.
This cannot really be achieved without sliding the boat on its underside. The protective strips and skids thus allow the boat to be slid into the water from such a bank without damaging the deployed instruments, or the boat’s propulsion system or control surfaces.
Propulsion and steering system The boats are powered by two independently controlled propellers and have two rudders.
The twin rudders and twin shrouded propellers with differential throttle control provide both redundancy in the system and ensure very high manoeuvrability.
