I've always carried or just plain dragged my SINKS around but the weight of the new T140 along with it's exposed rudder have me thinking I need a better solution. Wondering which cart you guys preffer for dragging / launching your Tarpons. Is there one that works well and stows onboard? Should I get one that goes in the scuppers or a filding stap on style?
Any and all advice appreciated.

There are a few out there, I like the paddleboy one with the straps and largeg tires for the sand. I think i have the air yedo or heavy lifter, i just know it has inflatable tires and works great. http://paddleboy.com/pages/center.html

Make one. I've got a T120 and made a cart of PVC & large mower wheels. The width is sized for the grooves in the hull and it fits in the tankwell behind the crate. Cost about $35. It's not great for soft sand but works great on everything else. I'll get a picture and post it tomorrow if it would help.

The first one I made used the scuppers but didn't want to risk damaging the plastic. Several guys had issues with leaks on some of the first 120s sold.

get one with big tires and as much width as you can get, tipping stinks- I forget the name of it but i got mine at KFS.

These wheels are not for soft sand. I don't know if the 140 has the same channels in the hull or the same tankwell width. This is sized for my 120.
