You should be able rig a live bait holder in the front in place of the front/seat passenger.
The weight of the water in the live bait holder will help balance the Oasis. You should be able to reach your live bait holder in the front seat area, much easier/safer than trying to reach around your back in an Outback.
Add the AMAs, and you would have a sturdy fishing platform.
The C Tug cart is easier to load the Oasis on and off as you don't have to turn the heavy yak on its side to put the cart into the scuppers. You just lift up the front or back and put the Oasis on the C Tug Cart and strap it on the cart. There are some excellent posts on using the Sea Tug with minor modifications to the belt. search.php?keywords=CTug&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=posts&st=0&ch=300&t=0&submit=Search
You can buy an earlier model of the Oasis since you won't need the steering from the front option.
The early models don't have rod holders, but you can put a gear box on the back with attached rod holders.
For a lad your size, you probably might want to upgrade the rudder to a bigger sailing rudder and make the Mirage fins bigger with the attachments.
If you buy a good older model, you should have enough money to buy the above options versus buying a new model.
