Without going into the physics of why, 10 - 15% of the trailer weight with the boat and a normal load is the proper amount. Like RWilson2526 said. Too much is just as bad as too little. Too little causes trailer sway at speed (We've all seen it on other peoples trailers as the go down the road) and too much will put so much weight on the rear that your front steering and braking will be effected. Great vid Ferm!

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
