Default How difficult to mount a stern rail on a lined hull?

The boat has a full liner and has never had rails before....how would I go about insalling them as I have no way to acces under the gunnel to insall a backing plate without removing the entire liner which isn't really an option. Is there a way?

If you cannot get to where there should be backer plates your install will not hold up !!!!!!

short of putting small acess covers your facing a tough uphill climb !!!!!!

Good Luck !!!!

John gives good advice if you use ony a few standard bases with screws.

But if you want to try, do a search on here to get the exact drill tap size for the SS screws you will use in the FIBERGLASS, dremel a V notch on the surface so the snugger fitting screws woun't split the gel coat, and use a liberal amount of 3M 4200 on the bases and the screw holes so that the glue provides you with more holding power than just the fasteners.

Several anchor points, oversized base surfaces with lots of glue and wrap around pipe to provide leveraged butresses will make this work.

There are bolts called Togglers. Garelick makes them . Basically they are stainless toggle bolts made for boats. I've had a boarding ladder hanging from them for 10 years, no problem. If you intend to leave the rail on permanently, I'd use 5200 to seal it. It has high adhesive strength. If you need a site that sells them, pm me. Hey Bull, wouldn't be a problem on one of yours. Could just weld em on.

My boat has access under the cap all around and like you say, welding also does a good job too.

But aren't those togglers a lot larger than the #8 screws used on bases?

Yeah but you just get the smallest diameter and they work fine. They're only 1 1/2 apart on my ladder. If he's having a welded rail made up, Which I would strongly recommend, they will take the mounting hardware into consideration.

Right Biddie,
If the pipe standers are welded to 1 1/2" x 3/16 alloy flat stock that runs parrellel to the top rail on the fiberglass rail, then fewer and larger toggle bolts can be used, and gluing down the flat bar with more surface area will make a lot stonger bond than using the more expensive bases with a lot of little screw holes.

Less holes in the boat too, and probably cheaper on a all welded aluminum or SS fab and install.
