Solar Electric Launch

Noosa River electric launch
Solar electric launch - perfect for those lazy summer afternoons

This was a really exciting project that we have recently launched for a Queensland client. The brief was for a design similar to the old Noosa putt putts from early last century that would be used for entertaining and canal/river cruising. We approached David Payne for the early design work and took his cinema launch design and stretched her to 23' overall. A local designer experienced in CAD design (Will Allison - Imagineocean Yacht Design) then digitised the design so we could take advantage of CNC cutting and computer design.

Noosa Launch Concept

                                                              Initial design concepts from David Payne

First up a video of the completed boat then some construction photos and information below.  Many thanks again to Adrian for his wonderful camera work and editing.  If you would like to watch a larger version please click on the YouTube button in the lower right hand corner.

Although we normally hand loft our boats, this time we opted for computer drafting and it has been very accurate and a big time saving. The molds were CNC cut and the building jig was assembled ready to plank in a few hours.

The boat is constructed using a specially profiled strip plank western red cedar core, glued with WEST System resins/fillers with a double bias e-glass skin inside and out set in ATL Composites Kinetix resin.

Power was provided by a Mastervolt Bellman 48v AC Drivemaster Ultra brushless motor and a bank of AGM batteries. The motor and technical support is being provided by Steven Mullie at Eco Boats Australia and his service to date has been fantastic - highly recommended. Charging will be primarily by thin film solar panels with supplementary charging available from shore power if needed. Under ideal charging conditions for the solar panels it is envisaged that there will be around 150 watts of energy deficiency at cruise speeds which is pretty impressive.

The hard top is constructed from Core-Cell foam, glass skins and a v-seamed ply layer underneath.  The interior is largely uncluttered due to the lack of an engine box above the sole.  The sole is laid teak and celery top pine.  The interior has been designed around the boats internded purpose and it contains plenty of comfy seating, a built in icebox, Isotherm fridge, sink and fresh water system, iPod dock, Raymarine instruments and an enclosed head forward.  The decks are laid teak and all trim timbers are Tasmanian blackwood.
