I would like to cover my P16 when not in use.

It will be stored on the trailer.
I was wondering if anyone has found it to be effective to buy a single large tarp and cover the mast,boat and trailer with one piece.

I found a tarp grommet kit and took a small tarp and cut it down to fit the front of a single hull - and popped some grommets in the part that I cut to tie it.

seems to work ok but i would like to be able to cover the boat quickly...

Ideas?
