Do you want something suitable for use while running, or something for use when anchored?
I have a Taylor Made 'AnchorShade' that I use while stationary. Not bad, and completely removable too.
The anchorshade looks like a giant square umbrella with 4 nylon straps at each corner.
I attach the straps to my midship and stern cleats and it covers the cockpit nicely.
Thanks for the compliments guys....I'm really enjoying the boat...my wife is a huge Stones fan and I like to Grouper dig so I combined the two ( actually my brother is the artist) to come up with the logo and name.
Wow, that looks great as setup on the Parker! That should be in their ad !
While I had never considered one (I love the sun) I can see its utility on those windless hot days and when you'd have kids aboard or others who can't take constant exposure to the sun.
