Have to agree with those above. You don't need the distance casting. What the boat is for in the first place. Get you closer to the spot without the cast. Onto standing up. Unless you have a flat hulled tubed boat, I would highly suggest NOT putting a platform on your boat. Even if you have it centered on the tubes, you'll find it's still not that stable. Just think of it as a rocking chair. Stand on top of one and center yourself. And no, having water surrounded the tubes doesn't make it more stable. Now, if it was surrounded by sand, yes, but water no. But try the chair technique on a hardwood (or tile, linoleum) floor. Now try adding casting to it. You'll see what I mean. I tried this YEARS ago. Didn't go well.
