I've been avoiding this thread because I thought it was the first thread (and I don't remember who) installed the little 2" plug in the ski locker so he could vacuum out the water. I didn't realize this was another thread and how long it had gotten nor how big a problem this has become.
That being said you can almost certainly add me to that list.

I know that is flotation foam but... why not just pull it out and make a bigger locker for ballast. You could have a bag made for that and easily get another 300lbs in the nose.

Got lemons?!?... Make lemonade!
