i checked my lee boards on our boat today *just for you .
The top rail grommets spacing was 4" *and also allowing for the vertical stantions.
The brass grommets were small and laced with thin *parachute cord, *or what ever you *wana call it .
At the bottom of the skirt / lee board *there is a 1.5" *sewn fold to accommodate a 1 " x *3 /16 " *aluminum metal *flat bar that encompassed the lower perimeter.
Several "L" brackets *made from the same stock were used to attach the lower bar to the deck, the bar was curved at the corners.
Our "mesh lee boards" were reinforced with" strata glass" so to avoid the grommets *pulling out , this is requisite.
Special Note :- *Lee boards can offer a *great resistance to the wind and need to be strong.
We went out for an all day cruise to day and got a little sun burnt , it was 72 degrees and flat calm.
Is it legal to fly a kite from a boat ?

Just for a moment we were thinking of you all
