A couple of months ago I added tennis balls to the cart to keep the dreaded flat spot from happening to the AI.

This has worked out well, but has also shortened the cart's reach, making it impractical for the deeper hulled models like our new Oasis.

So I simply extended the reach of the cart so it can now be used to transport all models without fear of piercing the scupper holes.

Here's how:

-- 2 pieces, 1/2inch schedule 40 PVC pipe, 3 inches each
-- 2 slip / thread 1/2 inch couplers
-- Duct tape
-- PVC primer and glue
-- epoxy glue
-- sandpaper or file

1. pry off the top cart caps if they are still there.

2. Since the connectors have a slightly larger outside diameter than the cart tubing, you must file or sand them down to match. I adapted a drill to use as a "lathe". When finished, they will fit something like this (note the slight bevel on the top):


3. When done, prime and glue them to the 3" PVC pipes, wiping away extra glue. Take 2 turns around the pipe with Duct tape (= 5 1/2 " long) to fatten them up for a snug fit in the cart tubing.

4. Check your fit and adjust as necessary; then epoxy the extensions into your cart tubes:

The cart cross bar now stays clear of the hull, eliminating your dent problem...

... and properly extends all the way through the hole for a safer, more secure ride for your boat:

You don't need the threaded ends, but if you find the need to extend your cart further later, you can simply thread in whatever you like.

Tip: If you bevel the top edge of your extension slightly, this will help the cart to slide past any ridges inside your scupper holes. 8)

I already put on a set of tennis balls on my trax cart a few weeks ago. Works great to distrubute weight better when rolling around an assembled island. I notched the balls just a little on the bottom so that most of the weight is on the scupper holes but the crossbar does just touch - I figured to displace weight on the bar and the balls.

Well, last week I lost the darn caps to the cart and utilized a very similar solution with PVC pipe & plug and a little electrical tape to snug PVC tube to inside of cart.

Your pics say it all, I never thought to post my lost endcap PVC pipe fix. The threaded end is a nice touch to either add more pipe or a threaded plug - a much better use of PVC fix.
