Chock measurements???

[Blown Away]

From a previous post I understand that the chock roller is set at 142" forward from the the center of the two axels but it doesn't say how far the boat hangs off the tail end of that particular trailer. Would anyone have knowledge of the approximate measurement from the stern, and also the approximate height? Thanks!!!

142" is the corrected dimension and is accurate on my trailer.

with regard to hangover, I can't answer specifically only that the amount is about 8" front and back over my 7' of keel rollers. 

You need to realize that one of the most important things is to get the tongue weight right so that your tow will be safe so that should be a focus of your design and setup. Moving the chock/winch post is one way to achieve the proper tongue weight.  That 142" dimension is right for my trailer but may not be for yours.  You may have to make adjustments after the boat is on in order to get this right.

revision to the post:  Upon further review it appears all of my overhang is on the front and none on the back roller.  Hard to see, but my last keel roller is in line with the aft most cross member of the trailer.  The back of the keel is forward of that spot, so little or maybe none of the keel is even on that last roller.



with regard to height:

Thanks Brackish....your photo helped a bunch. I have way more trailer than needed with enough length to eliminate any hangover, but not sure if that's a good idea for floating on and off reasons. If I allow hangover I will need to extend my square center post aft to allow my chock post to be mounted further back to get to 142". I made my roller frame 12' 7" to carry longer boats in the future if necessary. Anyway hoping to get this project completed this week.
