1. I prefer 5.8 rops and between 6-9ft in length. This gives enough length to drop the ball to the needed hieght and still tie off to your tower, or cleats.

2. I have 2 sections of rope i use. 2x 100ft, I normally only need the 100 but then I have the second if i need it.
I dont use an anchor buddy, If my boat is tied up its normally shallow enough I can walk out to it.

3. As above I prefer 5/8 ropes. 6-9ft I have several tied to my Exile Balls, then I keep 4 extra on the boat for what ever reasons I need them.

4. I have a pretty heavy duty rope I use to tow the big air plane wing tube we have. I use this if i need to tow someone in.

I have found the most important thing on the boat is Knife, flashlight, Fuses, Needle nose, reg plyers, cresent wrench, flat screw driver, philips driver, 3/8 ratchet kit with sizes from 8mm-9/16th. That covers almost any size you might need for an on the water repair.

I also carry 2 rider flags, incase I lose one or someone on the water needs 1. I have a real nice one then I always grab a couple cheap ones when I'm at the dealer or someplace offering them.
