Andrei, Have you considered this simple approach?? It's the method I used, and I love simple.? With the boat off the trailer, raise the center bunk board support so that it is level with the fore/aft supports.? Secure the new bunk board to each of the three bunk board supports.? Put your boat back onto the trailer keeping the center support slightly loose.? Once the boat is back onto the trailer, it will bow the bunk boards enough so that you should be able to tighten the center bunk board.? If your trailer is old like mine, it will not be hard to set the center support in the same position you found it.? I hope this helps make the process easier for you.

I replaced the bunks on my M17 a couple of times. Just measure the distance between the bolts with the old bunks installed. i.e. along the curved bunk.

Dear all,? ? the bunks for the trailer for my Monty 17 need to be replaced (they are > aged and cracked). I have two questions for the knowledgeable people on > this list:? ? a) the existing bunks are curved, but the 2x6's I bought at my local > lumberyard are (obviously) straight. The curved ones should be slightly > longer than that the straight-line distance between the mounting holes on > the trailer. Where should I drill the screw holes in the wood?

Or > should I drill the holes as if the bunks were already curved (slightly > farther apart), but then I am not sure how I will mount them without some > weight to curve them down (the holes in the bunks will not align with the > holes on the trailer). Any suggestions?

Glue and > staples is more work, and requires the whole thing to wait 48 hours. > Would the carpeting start to bunch up if I didn't put in glue?? ? Thanks for any help,? ? Andrei.? ? P.S.
