We have the big wheeled Hobie cart and its big tires float in the water which make it difficult to get out of our Oasis or in.
This new cart should work on the PA's with its 160# payload.http://www.austinkayak.com/products/562 ... olley.html
Just curious about your launching technique. Do you walk your PA out into the surf and then pull the wheels out from beneath, or do you tip it on its side on the shore to remove the wheels and then drag it into the surf? I had considered doing a similar mod, but the beaches I launch from are mostly rocky, so I end up attaching and detaching the wheels while floating in 2 ft of water. The bouyancy of your larger wheels seems like it would make that technique more difficult.
