I'm getting ready to do some work to my rig. I have a Lund on a trailer
that looks like a combination of three trailers, plus some homemade
welding
thrown in. In the back at the heaviest point are two planks that look
like
they have rollers in them that support most of the boat's weight. There
are
two side guides, and the receiver Y shaped rubber yoke in front. Should I
add a couple or three of spool rollers under the keel? I do need to add a
couple of little guides up front where it sometimes does not come
straight
into the Y if I am too deep with the trailer. Or should I watch the
loading
more closely, and try to power on? Still, powering on, with the flat
planks, the boat may tend to miss the front Y. If I can get it centered
on
the keel rollers, it should be kept straight by the two side plank guides
that are just under the gunnels when the whole rig is out of the water.
Just how much support should one put under a boat on a trailer?

I cant understand why anyone would own a Bunk Trailer. Get rollers.

Thank you for the help.


Bunks work very well. Especially on light aluminum boats. My heavy duty
aluminum boat sets on bunks faced with UHMW plastic. Boat slides real easy.
Rollers on thin guage aluminum will bend the aluminum in the contact area.
But my Valco 14' had the front keel roller support fail. And the boat
rested on the front of the bunk, and cracked the bottom at the contact
point. So after welding the bottom, I extended the bunks far enough forward
that the boat could not rest on the end of the bunk. Plus there is a less
problem with a bunk that rollers. And do not use treated lumber for bunks
on an aluminum boat. The copper will react with the aluminum.
