The sale of STING #1 will fund the building of the 3rd STING 600 to complete the Trilogy.
This will be the STING 600 Mini Coastal Cruiser having a double berth, galley and navigation area. Both center board and rudder are auto kick up if hitting an obstacle.

Video showing main hull kissing water at 9 knots.
Winds forecast for 15 knots at Tin Can Bay so made the decision to leave screecher at home.
Unfortunately winds proved to be much less and our average hull speed with jib and mainsail was 7-8 knots..
On 17th November at Lake Macquarie further foiling tests were performed.
We did manage to fly STING #1 which was a thrilling achievement for me and Steve Duf on the helm.
The chase boat didn't turn up to video and video i took on boat has proved to be a problem to show on web site. I plan to return to Lake Macquarie soon and Chris Johnson who took photos and sailing video at last years Multihull Championship will document foiling. There are a couple of improvements that i'm now working on along with two lightweight bench seats 1.8m long that clip onto outer hulls.
A big thank you to Chris Johnson for allowing his video and photos taken at National Multihull Championship

Peter has CNC machined foil plugs and is currently programming the blends or knuckles for my differential two stage foils.

STING #1 was towed by local Coast Guard. Peter Schwarzel joined me for this important first foil test. Peter has engineered the foiling profile and performance modeling along with the structural laminate construction for elevator and forward wing foils. Due to impending 20 knot winds and rain squalls our tow testing was limited but sufficient to prove foils had adequate lift. The forward foils were set in the plumb position and the two stage differential foils performed as design. We only needed to adjust rudder elevator two clicks to achieve flight. The turbulence from the tow boat two propellers was extreme and we were amazed that the wing foils produce any lift at all. Our next test will be under sail during the comming months.

2018 National Multihull sailing report
STING #1 very first sail was at Wangi, Lake Macquarie the day before the National Championship. With very little time to evaluate and sort out boat the Sunday shake down non official race showed STING #1 potential.. We came a close second behind a Farrier super charged 6m Tramp. ( we had mistakenly sailed division 2 course which is a 3rd longer ).
Race 1: still getting used to boat we won line honors
Race 2: decided not to race and sorted boat ( by doing so cost us first place in Championship. after completing all 6 races one race can be dropped but last two races were canceled due to 30-40 knot winds.
Race 3: being the only long race gave us a chance to show STING #1 over all tremendous speed ( see video ). We again won line honors with Farrier Tramp with mast head spinnaker, square top mainsail expertly sailed came in 55 minutes later.
Race 4: the night before race winds were predicted at 20 plus knots so our race plan was to leave screecher in the van. As it turned out winds varied from 10-18 knots. all other boats flew screechers / spinnakers and with just Jib and mainsail again took line honors. Race officials then adjusted our handicapped rating which placed us into 3rd place overall.
