Just prior to christmas we were luck enough to help Sydney University 
At Sydney Uni’s Australian Centre for Field Robotics we have a project involving a robotic autonomous surface vessel (ASV) tending a few small underwater vehicles. We are aiming to use the system around Jibbon Point and collect seafloor images with the little robots with the surface vessel picking them up, recharging them and launching them again. 
We will be doing day trips from Cronulla Marina using the NSW DPIE R/V Bombora over the second half of November, and we are hoping to find a place nearby to assemble, launch and hopefully leave overnight the surface vessel. Your sailing club looks like it could suit quite well. We'd be happy to contribute to supporting the club and be invoiced for water access and storage, services, etc.
The base system is a WAM-V 16' catamaran https://www.wam-v.com/wam-v-16-asv
Our system weighs around 300kg fully assembled and is about 5m long and 2.5 wide. Here are links to a couple of photos and a video of our system during recent trials at the Scouts water activities centre in Woolwich
After the Trials
Thank you so much for hosting us.
It made a huge difference to be able to have easy access and convenient, safe storage of our gear.
Everybody we interacted with from the club was incredibly helpful, friendly and welcoming.
Hopefully, we get to do it again!
Thanks again,
