Here is a pic of the tray that David Langston has in his boat. He can probably speak into actual usage of the tray more than anyone at this point...
He sent me this picture after he got his tray and he said in the tray he has a box anchor, shore spike, 4-12 foot docking lines, 1-100 ft anchor line, 1-50 ft anchor line, one tube rope, one wakeboard rope and handle, one surf rope and handle and about 6 bungee docking lines.
The tray is about 35 inches long and 28 inches wide. It is about 5.5 inches deep in the middle. Hope that helps. I haven't checked to see if it will fit in a Helix, but I will check later today...
