Cat trax

We just bought a used Hobie 16 and I am planning to buy Cat Trax to wheel it to the water. Our beach is a pebble beach and I wondered if the hard wheels or the ones filled with air might be the better choice.

The air filled ones are better in almost every situation especially uneven rocky beaches.

Thanks for the advice!

Just note before you buy... there are a couple of work arounds which could save you from money instead of buying new $500 cat trax. I've heard of some pretty good ideas in the past (especially for those on a college budget). Here are a couple:
1) Looooong strips of used carpet. I picked some up from my friends who are house flippers. A knife can cut it to size pretty easy. They roll up conveniently too. Only bad thing is they can get stinky. pu!
2) Hobie 16 has deep V hulls. Is pretty easy to just take some PVC pipe and cut it in half long ways (forming a half pipe, not two sections of pipe). Can lie them out behind the trailer and slide the boat on/off them and into the water. The guy I sold my boat to does this at his lake house as a makeshift hobie 16 boat ramp.

Thanks Bboyslug.

Awesome, glad you shared that one, I'm going to install a set at my lake house when I go up next time, there's a power line at the boat ramp I have to avoid and am only about 8' away, I wont have to rack my nerves anymore with that set up!
