New rod holders. question?

[Robert M]

Installing 6 new LD swivel rod holders this week, was planning on using some pieces of starboard under rails for som added strength. Does anyone have a better suggestion?

Get the metal backing plates. if not i supose the starboard is better than nothing. I have metal on the bottom and some holders on the wash rail have starboard on top.

The bottom of rails isnt flat. I noticed on my other rod holders that where installed durring build there are 8"x7" plates that seem to contour with uneven under surface of rail.
ill take a pic . are the metal backing plates your refering to an Ld product? Cause I got them, just want something larger to distribute the load before the plate.

If its not level Id bond in some material to level the area and distribute load and use a stainless backing plate.. the more energy you spread out the better.

 

[Robert M]

Agreed. I was planning on cutting out starboard ( large as would fit) glueing it under rail before drilling through. Then using backing plate that came with holder on outside.
Does any body recomend a good bonding agent to use. I havnt decided if layering the underneath of rail to make completely flat is on my list, Although I realize it would only strengthen the rail and holder, I may skrib a shim out of the starboard. I guess its 6 of 1 half 12 of another.

Glass isnt something i have worked with before. Although I guess this would be a good start seeing how in cant be seen, and is under rail.

Besides the metal backing plates you should support your rod holders close to the bottom of the tubes. This week I'll get better pictures of the supports. In the first picture you can see the safety line resting on the support. On the right side of the second picture you can see a better picture of the support.

I believe the LD rod holders will come with the backing plates.

We made these braces out of scrap nida on the Emily Rose.

Maybe you should consider having somone knowledgable in such matters local to you install them? It may be easier than trying to learn as you go while trying to work inverted.

Installing rod holders may be the one thing on a boat that I think I can handle, I spent the day walking around 20 tuna boats in Gloucester MA. Including some of my good buds. I was merley asking if someone had a better matterial then starboard, I realize I could have custome aluminume brackets, or I could heve glass bottom supports made and fastened to my boat , but then I would have the most sturdiest holders in Gloucester. Stronger then my buds that catches close to 100 fish a year. That may be over kill for 3 or 4 I "WISH" to catch.

Frigate , el mar, my sarcasim doesnt apply to you , that is some nice work.

Great advise for a downeast boat forum? never thought of just paying someone .
Brilliant !!!!!

It was only a suggestion as you dont sound like you have done much glass work or cutting holes in your boat. My suggestion doesnt mean you have to pay anyone. But a forum member up your way or somone on your dock might be able to put eyes on the project and give you advice or help with the install. Im sure the last thing you want to do is make an error and have a fish turn your gunnel to sugar. What you are asking can definatly be accomplished many ways. I wasn't trying to insult you.

Ok , Ok I get it , sorry for misunderstanding you. The reality is like most things in life its only scary the first few minutes. After the first hole drilled today , it was easy peasy. I cored out holes that where 1/8 bigger than holders, sealed inner edges etc. I also stopped at my local machine shop and had 8"x8" 1/4" alluminum plates made. I figured they would distribute some of the pressure of my imaginary 1000 lb tuna. The reality is after the first holder I installed A quickly relized that the backing plates that came with the holdrs had a bit of flex in them, Although very stiff. The fact that i could crank the back plates tight and have them semi mold to under rail, seemed much stronger than having a huge plate floating.

I mean you can make the surounding area as strong as you would like but the reality is , the holder is only as strong as the rail. needless to say I installed them all today , And im very confident that my holders will stand up to my imaginary tuna. A may or may not in the future ,reinforce botom of transom holders. Thanks yal!

Great news Robert!

Did you bed your holders and backing plates with 4200 or somthing similer? Also did you fashion any supports for the bottom of the holders tubes to counter act leverage from the rod and fish?

Yes holes where securely sealed, along with a marine gasket sealer I used on the bottom side of holder flange.

I have not yet secured a leverage bracket to any holders although I am contemplating fabricationg something to mount on inner transom for rear holders.

After walking around my marina yesterday and inspecting more than 10 commercialy fished tuna boats, I only found one boat that had there rear holders secured in this way( tuna.com)

Thats not to say Its not in the works, I think its a good idea, just not gonna be in the garage today with a block of stainless at the cc machine.

Note to self... Robert has a CNC machine

 

[Robert M]

oh no , I was just kidding!

Trust me if I had a cnc machine , not only would I have some nice chunky stainless rod holder reinforcments, but also under water machine guns, ejection seat, and a kick ass bow ornament of a mermaid riding a blue fin, just saying:wink:

 

[Tuna Pursuit]

I just secured the fighting rod holders(2) on the bottom. Everyone has a favorite holder they like to fight the fish in. I can punch & bend you a couple out of stainless, I'm in Lobster Cove, you can come & see how I did mine.

LMAO!!! This made my day. I can picture the mermaid riding a bluefin and I WANT ONE!

ETA .. its not a bluefin but proof of concept found!

Regardless of what backing plates you use. Make sure that you remove all of the gunnel coring where the bolts go through. This way you can tighten them down without crushing any core. Also I assume they are straight replacement and you are not changing the rod holder angle. If so you will need to fill all the rod holes and redrill so the new units are nice an tight. Starboard, nothing will stick to that stuff. ¾ Marine plywood with a coat of resin should do fine in addition to the metal plates which will sit on the plywood. If the surface is uneven towel a nice heavy coating of Hull & deck puddy on the plywood and push it into place and tack it up with a few panhead screws. Once dry just run the hole saw through to plywood.
