Spray rails

Post by Tony Hain » Fri May 13, 2016 1:36 pm

Screw spray rais from the outside and plug or screw from the inside?
If you screwed from the inside through the chine it would be easier to replace if damaged. Yes or no?
What type of sealant would you use to attach the spray rail?

this is what I did... I screwed mine from the out side...my thought was that if I need to replace, it would be easier to find, cut, or grind down the screws from the out side...
I put a light coat of epoxy on my spray rails ... to coat the inside, and if it made a hard bond... I could use a belt sander to remove...


Not sure of the boat your building... and I am really good with a belt sander...
Hope this helps...

I used the same method on my Tahoe as specialk for the spray rails. On the hull guards, because they're wider, I screwed them from the inside. Not launched yet so too early to tell how this plan will work out.

Suggestion: Screw from the outside, then cap with a stainless 1/2 round.

Spray rails are semi-sacrificial. If you hit a dock too hard, you want to be able to replace them and not spring a leak.

So when you drill the hole to mount them, drill out the hole, then epoxy in an oak or mahogany dowel, then screw into the plug. Oak/mahogany won't rot out (well, it will take a long time) and provide great screw holding. Cap the rail with a nice SS 1/2 round. Do this into the chine, so there is plenty of backing wood.

If you hit it hard enough to break it off, the hull (hopefully) won't have a leak.

If you go from the inside, bed it with plenty of bedding compound.

LOL I epoxied the heck out of mine on, and screwed/plugged from the outside. Screwing from the inside left way too much guesswork, and difficult access.
