Funny video showing Jim Luckett from SailBoatsToGo sailing the W500 twinhull kayak standing up, without outriggers:

Yepp, but what`s it about ?
Everyone having sailed bigger sized non-ballasted-centerboarders knows it.
U can feel that it`s "safe" --sailing in equilibrium.
Few helmsman inform themselves and know why it isn`t sailing on the edge.
In Germany we have a lot of experience with "narrow" boats without ballast and a lot of sailarea. They work well, pretty save and fast.
Obviously it looks like sailing on the edge, but...

The Brits show the same principle with their cruising-canoes. Do u know "Rob Roy" that travelled thru the baltic, nearly whole europe and israel ?

There has been an active race class with those boats, can`t find a link, sorry.
The racing led eventually to this fascinating boat:

After the WWII our grandfathers and fathers built little boats from the half shells of supply-bombs. During war those "bombs" came down with a parachute , they contained food the troops.
In North Germany there has been a class for those narrow alloy 10`boats.
Sailin`with scrap , sails made of old anything--post war `50s !
