The better quality trailers with out center rollers are much better- the problem with centre rollers is that the boat if it is being powered onto the trailer can come off the rollers and damage the boat.
Also a big problem for slipway owners is prop wash undermining the end of the slip.
So I would say by powering the boat onto the trailer you are risking damaging your boat, prop or trailer and also being antisocial in destroying the end of the slipway
I have never seen a boat trailer without a winch - it doesn't mean you have to winch the boat on!
Trailer without centre rollers do not support the keel of the boat - not so good for the boat either!
Prop wash does no damage at all to a concrete slip unless it is in poor condition already
Sorry but I disagree with all of your comments! All IMHO of course!
For example slipways in Salcombe, Plymouth, Dartmouth and the new one in Torquay all local to me are all in good condition and by powering the boat onto the trailer you are out of the way in a fraction of the time compared to winching it on making it possible for more boat owners to use the slip and get their boats out faster.
