I have a question about two basic styles of rails I've noticed on DE boats. On my 36 H&H I have a full length spray rail that is a 1258-R from Hamilton marine.Calvin Beals and Young Brothers on the other hand have appears to be a short shot of 1258-R and a shot of 1520-R mid-ship. What is the reason for the different styles and is there a benefit? How do most install them, thru bolt(how do you repair/replace) or screw.

Contact Mark Demers at Integrity Marine. He is the VP of sales at Barbour Plastics and sold me my spray rails. He knows everything about spray and rub rail- I'm sure he can help you out. I used the R1013 rigid rail and it was fairly easy to install. I predrilled every 6", countersunk drilled, placed on hull as I desired, drilled in three spots, dry fit with screws, then drilled the rest. I used 5200 to bed and used SS bolts, washers, and nylon nuts. I went with heavy duty 1/4" bolts and no problems.

Clark Island Boat Works has some good photos on their website- they go one more step and putty and fiberglass over the inside nuts to make sure they never leak.

the picture directly above -
that boat has 3 rails,yes ?
starting from the stern - it's a quarter guard - this keeps the hull off the dock
next,is the lifting rail - these help "lift the hull"

the fwd are spray rails...

the "two-piece" spray rail is a spray rail and a lifting rail. the aft rail is using the water that the hull is displacing to lift the hull out of the water.

the theory is less boat in the water better speed.

the continuous rail is doing the same thing it just looks a little better to the eye but might not be quite as effective to get you the lift your looking for. but maybe that hull isn't looking to be lifted.

we use the seperate spray rail and lifting rail the benifit being that you can possition the lifting rail low enough to be effective without worrying about puting the spray rail 2 feet lower than you wanted. we also stop the lifting rail 3-5 feet short of the stern to allow the water to break free from the hull. if they run the whole length they can drag when the boat is moving at higher speeds.

thru-bolt when you can, screw where you can't, lots of 5200, and if someone is going to pick the boat up with a travel lift make sure they use blocks to avoid putting strain on the rails.

im sure none of these early morning ramblins aren't making any sense. i'll try again later.

Jawz, I understand the lower guard(quarter).My question is why on the Calvins do they not run the lifting strake(rail) all the way fwd like on the H&H? Are they different sizes.Does the larger size give the boat more bottom which in turn helps perform better in a following sea.I understand about giving about more lift which in turn increases speed. Just wondering.

in most cases we use the 1258-R for lifting and spray rails. in rare cases (once) we used 1520-R but that was at the owner's request.

i didn't see an improvement. its been my experience that the placement of the rail is much more important than the type of rail being used.

If you install them make sure you block them when hauling. If not you will bend screws & bolts and snap a rail.

What Size Spray Rails

Okay just to give a little background on myself. My name is Joe Durante, and I'm building a 19' Downeast Boat [got the plans from John Gardners Book]. My question is on the Spray Rails, how large should I make Them, 5/4" X 2"? Is their a ratio I should observe. Still got a ways to go with the build, Hope to have it completed for the 2012 season...

Joe ... I've been thinking about your question since you posted it. Is there an online photo of the design that you're building? Can you scan in a drawing of it? I have a thought if the above aren't possible but let's see what you can provide first before I go to "Plan B". Thanks ... DE

pjitty- R1013 Rigid spray rails work well for your sized boat (same as Eastern Boats). See my earlier post for contact if you want to buy direct.

I just went out to the boat and took some pictures, Don't have a clue how to post them. I've copied [photos] several boats from the internet and I can scale the spray rails from the photos. I'll figure it out, not really a big deal. Thanks for the Help...

PS:
Hey Eastporter, just went on your site. Put it in my favorites. Thanks for the Help...

Your boat is coming along nicely. Please show us more photos and tell us what you did. Are the plans to scale or are you making your own patterns (I believe this is called lofting)? Is the hull cold molded (glass over wood)? Ply or strip planked for hull? Now you've got me intrigued. ;)

26' Seaway
Spray rails

This is a great discussion as I am looking into improving my rails over the winter. I have a 26 Seaway and it has your typical 2 spray rails on each side. The problem is, I find that on a descent day the only spray that is making it into the cockpit is created by the spray rail mounted towards the stern. The swell created by the boat in a moderate chop actually hits the front of the rail and sends up a light mist which gets pushed into the cockpit with any kind of broad side breeze. I imagine a one piece rail would prevent this, however that would require removing the current rails and would not improve performance. (i don't think?)My thought is leaning towards lifting rails which I don't know a whole lot about but i know that they eventually run under the water line (I believe) would this serve two purposes eliminating some of the spray mentioned above and improving performance?

We removed our rear spray rails on our 26 seaway. We did it originally so that we did not have any edges on the hull that could chaffe off a fish if it charged the boat. All that is left on our hull is the front rails. There has been no ill effects of not having them. The hull is actually much quieter on the drift or sitting on the hook without them. Nothing to slap the water. We do not get any spray in the back half of the boat without them.
