A heavier boat simply puts heavier
"Newton" forces against the tie down when you turn or hit a bump..

scratching head....remembering fragmented bits of high school physics More
mass, more tendency to STAY in motion. I say tie down the transom.


Aren't we saying the same thing? A heavy boat presents greater forces against
the strap. Gravity will not keep it on the trailer if it starts bouncing or
swaying.
