Maybe I have been backing into the water too far, I'll try next time as the
water won't be warm enough for comfortable wading in Minnesota. Its my
recollection that the bunks once dry stick to the hull and don't slide
anywhere. I have always had to float the boat off (submerged hubs and all).
I have seen some kits that convert bunks to rollers, but have also heard
that bunks are best for boats that live on the trailer most of the time,
especially with lighter weight hulls.
So do tell. Do you have rollers? If so, are you leery of "denting" your hull
by leaving the boat on the trailer 99.9% of the time?
