Ok, more feedback wanted. My daughter is 5'3" (when she stands straight) and 100 pounds. She's going to be moving this 11' board from the vehicle to the beach. She will have to go over sand, sometimes a good deal of it.
Any suggestions on whether The Mule can handle the sand (sometimes powdery, sometimes packed) or whether I should buy/make a modified Kayak cart
I used one of these things: http://tinyurl.com/yegx5ee
for quite a few years when they were made by Rolleze. Since then they've been made by WheelEze and, IMHO, the air valves have been improved to straight-up Schraeder valves instead of those needle jobbies like on a soccer ball.
Maybe our sand is atypical, but I cannot imagine a solid wheel rolling over our sand. Through it, yes... but not *over* it.
Call me a wuss, but I find that pulling something that sinks into the sand is a *lot* harder than pulling something that rolls over the sand.
The WheelEez tires run about 2 PSI and roll over our sand quite nicely. They also do a good job of enveloping irregularities like SUV tracks.
I used to haul my 9/6" wave ski or my 20' surf ski, paddle, life jacket, 4 beach chairs, a beeeeeg cooler full of food, a beach umbrella, plus assorted towels and beach bags for four people.
The only downside of the low-pressure wheels that I perceive is that they take up more space than a skinny solid wheel - and I dealt with that by hanging the thing on the bicycle rack in back of the vehicle.
If I bought another one, I *might* go for the next size larger tires - but more to get the load up to where I could pull it with less tilting of the board than anything else.
