oh im using them, im saying the previous owner said he never did.
What's special about an inboard? Physics is not partial to what a blob of material looks like. It is a weight that is in motion. An object in motion tends to stay in motion and that applies to any axis - not just fore/aft. Lots of folks overload their trailers, they use a clothesline rope on their winch, no safety chain and no stern tie downs and get away with it. That doesn't make it safe. It makes them "lucky"
when loading the boat off the lake i can get it on the trailer but not far enough up to get the bar set on the bow mount.
i basically have the whole dang trailer under water. i use the winch to pull it up as far as i can but as soon as i release the winch to put the bar on the boat slides back.
