I installed the first 5/8" thick laminations of the spray rail to both sides of the hull. I bedded them in 5200 and used my Raptor with one inch plastic nails to hold it in place along with a few drywall screws here and there. I soaked the rails in a long piece of pvc pipe for about 48 hours. I pulled them out and temporarily screwed them in place. They dried in about 24 hours. I waited a few days to remove them and when I did, they help about 80% of the curved set. They went on with very little bending effort. Next week I will put the second 5/8" lamination on. The second layer will be epoxied to the first and I will drive bronze screws through both laminations and into the chine. I have used the soaking method before and I really like it. You have plenty of time to make the bend. It doesn't work as well as steam and it won't work so well on larger pieces of wood. But, a lot less hassle than steam !! I am pretty much putting these rails on just to keep Dr. Bryan J dry in September !!! I think if I had it to do over, I would just let him get wet !!

The second and final laminations are epoxied to the first lamination. The spray rails have been rough sanded and attached with 5200 and bronze screws placed every 12" along the rails. I still have to plug the screw holes, fill a few bad spots, coat with epoxy resin, paint, stain, and varnish the forward ends. There you go Bryan !! I hope they work......

I think you'll be much happier running her.

Neel; Can you explain to me why you needed the rails? Is there a potential problem for me?

Doug, I have stretched my boat to almost 19' which allowed for a forward cockpit. Two people fit up there. When I go over a wake, as the bow comes down, water shoots up the hull sides up near that cockpit and the people get wet. You also get a little wet in the back. It seems like the water hugs the hull sides as it comes up and then curls over onto the deck and then aims for everyone in the boat. I don't think you have stretched your Gentry, so you may not have the problem. I do think rails should not be an option on a "stretched gentry", and maybe those with the standard length Gentry could give us their opinions on this. I would definitely give the spray rails some thought.....I will give a full report as soon as I can get her in the water. Neel

Neel,
I noticed that your rails, at the rear, is perpendicular to the side, not in plane with bottom. Is that the recommended orientation in the plans?
I added rails to my Malahini, after the fact, and tried to shape the rails in plane with the bottom for the last 1/3 of the boat. This is the approximate planing surface so the rails are an extension of that surface.
On the forward 2/3 of the boat, the rails are perpendicular to the hull and deflect the water down and out.
I am wondering if this will affect your boat when on plane?
BTW. I did them in one piece (13/16" x 1") and steamed them. It was quite a pain to work on the boat while on the trailer. Recommend the rails for the Malahini and do them before the flip.

Neel and Bob

I don't know what is best. But, started at the bow with them perpendicular to the topside (bottom down). I then started rolling to horizontal/parallel to the water. On the Bartender they end up parallel to the bottom because it's double ended.

Bob,
I followed Ken's recommendation on the rails. I installed them exactly as he did on his Double Eagle. If you go back a page on this thread you will see Ken's post on the subject. Here is a link to his build thread where you can see pictures of how he did it. I do agree that if spray rails are going to be installed, do it while the boat is upside down if possible. I am sure when it is all said and done, both of ours will do the job. Here is Ken's link: viewtopic.php?f=9&t=26168&start=30&hilit=double+eagle

yes, my rails are (bottom edge) are perpendicular to topsides.
as the topsides flare outward, this makes the rails turn downward.
I get a effect of the rails actually turning the bow spray down & out from the boat.
Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! :roll:

12 coats of varnish on forward part of spray rails. Two coats of bottom paint on boat and spray rails. The only thing left to do is paint the white boot stripe on the rails. I also have to figure out a way to hold down the new rear hatch so it doesn't end up on the Interstate like the last one did.
