Oh HULL no!

[BigDaddy]

Im curious about these marks made from trailering my new (to me) boat. Is this something I can remedy, maybe with some new kind of guides? What about the poor patch job the previous owner did on the front of the hull? What do you guys suggest? The boat is dry as a bone, but the "repairs" are ugly.

It's to the point that you probably need to start doing something about it.
When you see glass threads it's time. It can absorbe water with the damage in the pictures. Clear glass is ok to a point.
Cleaning with a medium wire wheel, lightly sanding and feather edgeing then (if no cloth in needed) paint with resin. Scuff and finish off with paint or Marine-Tex.
A roller in conjunction with the centering post may reduce the friction wear to that portion of the boat

Yea you need to sand that ll down and add some cloth and re sand. Then Marine Tex or Gel coat.

As far as the trailer goes, you might have to raise the bunks, as the thing looks like it just rests on the beams?
Put the trailer deeper in the water and float above the trailer, hook to stop and pull out slowly, let it come to rest on the trailer this way you are not winching it up and hitting the trailer.

What about some roller guides or something to support the boat other than the rub rail under the "V". Do you think I will have to cut the cross member that the "V" sits on now? I have been thinking about how to get the boat off the trailer enough to put some glass under there, Im not sure about what to support it with or how big the make the pads, or where to place them. Obviously I could use some of your guys's expertise with this.
We went out on the 4th and I did back down further on the ramp to try not drag the "V" across the rub rail, but I almost had an F-150 in the drink due to the moss on the ramp. As far as the rubbing it worked, but it was touchy getting out.

To me everything looks fine except here:

Putting a roller at this location should stop the damage, now how you do it is a different animal.
Being you got an aluminum trailer, it would be prudent to continue the theme. Most likely in order to support the bow without redoing the whole trailer you may need some help from someone that can fabricate a bracket in order to bolt it to the beam near that location.
A 12" roller with 5/8" rod should work (if you have the room) bolted to the rear or front of the problem area and leaving the centering posts.

Being you got tandem, you should be able to pull the boat back (with the truck attached) by tieing to a tree or pushing with a strong back (son in laws), just far enough to clear the work area. If the weight is balanced or heavy on the tongue you can disconnect it or support the transom in order to disconnect from the truck to perform repairs.

Something like jjBroc has?

I'm lookin for the thread with that picture and can't find it.
Can't see the roller in the picture of his that you posted.
But it don't look like I'm describing.
I like the lack of rollers on the trailer except at the bow contact with the trailer.

[tsubaki]

Trying to achieve this but without redoing your bunk situation and leaving the centering posts.

if it were me, I would raise the bunks

[parishht]

Sell that trailer and look for a good roller trailer.

I love my rollers and my friends do to.
They like the way I can power load and then they only have to crank about a foot of cable.
