I left my Cuda 14' sitting right side up, on a Yakima roof rack, with pool noodles on each bar. It sat there for 3 days. When I took it down, there were 2 indentations, that went right through the contours of the hull. Luckily they came out. I have a pulley system, and always hang the yak upside down.
I'm going to cut some tie downs to fit my rack, and yak. My idea is to make something with an s hook, or j hook on each end, make it with shock cord, or wide strap, and make it to a length that when stretched over the boat, it will have the correct tension to hold the boat to the rack. Custom tie downs.
Always be aware of your gear, and its positioning. If you have a rod mounted horizontally, vertically, or extending off the boat anywhere, it will invariably catch a stump, tree, overhand, dock, or bridge, as you pass by, or under. I've almost broke my entire arsenal when going under a dock, with my rods sitting vertically on my crate.
I rarely use a ramp. There's almost always a place where I can drag, or carry my boat, and gear to the bank.
USE SUNSCREN. I've found it better to wear long sleeves, sungloves, neck buff, ettc, Cover as much as possible.
Practice loading configurations that balance the load.
I don't have an anchoring system, but I will soon. The anchor need to have a quick release. A deployed anchor can create havoc in the right situations, and it happens fast, leaving you with few options.
Make sure you can pull your anchor in both directions.
I'm going to try a plow style anchor. I've had a ton of problems with the claw style, or hinged claw style.
