When I first got a Wave I ordered the jib kit and spinnaker kit from Hobie. Neither worked.
There was no way to get luff tension on the jib, making it only work on reaches.
The spinnaker was worse.
That was how I ended up developing the Hooter.
Spent a season speed testing the Hooter against son Dave on another Wave. Changed things like pole length, where to put the halyard block, sheeting position, etc.
The standard Hooter is very fast and can be carried upwind, reaches and downwind.
My plans for the Super Hooter are not working yet.
