Before i laugh at others , here are some of mine and how i rate them.
Somehow showed potential , ( board rode a little higher and planed through lulls better ) , to aid light wind planing but it only worked in fresh water , ( go figure ) ? Maybe too much drag in saltwater . Lost interest . May revisit and change angles one day .

Absolute crap idea to make it plane earlier . I suppose it did a little , but it made a crap board even crapper !

Foil on RB , a copied idea . It is a good idea and works . Ive only tried three times so im still in crash mode . Had a few short , kinda controlled flights.
It was light gusty wind with an 8.7 sail. Have high hopes of this working.

Although this is not my invention , V gripping a boom before covering is absolutely fantastic . Very high recommendation .
