Fuel Tank Grounding Help

[Seadog]

Boat Porn as requested. This gives you an idea of the progress.













In this shot you can see a piece of solid oak I used in the bow for the bow eye.  This will be the only wood used in the boat besides some mahogany trim around the console.  Resin doesn't penitrate into hardwoods like oak
very well so you have to make sure you have good bonds around the wood to hold it in place.













I left out the aft bulkhead in the fuel compartment to have better access glassing in the Kleg.  That will be added later.  Transom is 1.5" Coosa, stringers are 3/4" Kleg, floor will be 1/4" kelg.  Ran a piece of PVC tubing from the forward compartments, under the fuel tank to the aft bilge for drainage.  That was a major problem with these boats as they were originally designed - very poor drainage forward.

More shots soon as soon as I can figure out how to down load them off the new camera.

absolutely amazing!that boat is going to be solid!

Lookin' great  :!:  :!:  Going on 2 years? Definitely a big project.  You probably don't want to ever see a grinder again    
Question: Is 1/4" going to be stout enough for the sole? If someone was to jump in from the dock, could it handle that?  I've heard stories where a person went that way because of the weigh savings and was very disappointed because of how flimsy it ended up being.

Thanks Pete!

Rick - Be 3 years next month. I've heard those horror stories too. And to answer your question about 1/4" kleg being enough support: I'm not sure if it will be or not, but I think it will.

In the last picture above those cross members running to the side of the hull are about 15" apart.

The hard part is going to be filling the spaces with foam. The trick is to fill ALL the space with ONE single pour.  Lay in the floor and glass it in, drill the access holes, then pour way. If you have to do more than one pour to fill up the space there is going to be some air space created between the pours.  The air spaces will compress, probably fill up with water over time, and give less support.

I'm using FGCI's 2:1 epoxy throughout. 5:1 on the transom. On the floor the schedule is 5 layers of glass on each side - 3 layers of 17 oz DB and 2 layers of 17 RW.

No mat at all.

We'll she how she does.

Back to grounding the tank - Anybody know if the fuel fill should be wired to the fuel tank tab?

[JimCt]

Not sure if it's really needed but I plan on grounding all elements of the fuel system. Not a big deal to do, just one wire from the filler to the tank tab.

Concerning a single pour for the foam, I found estimating the amount of A & B to achieve a certain volume of foam expansion isn't easy to do.  The info. sheet with the foam kit will tell you the expansion factor but a small variance measuring A & B can make a big difference in the final result.  I foamed my stringers in several stages and found with some care voids could be avoided.  

Progress looks great!

one question where's the label for your tank, check this link for installing tank http://www.yachtsurvey.com/fueltank.htm

[Seadog]

Tank doesn't have a label.

Is that important?

The current concensis on the tank installation link is that Pascoe probably

did not have a 22-2 in mind when he wrote it.  That recommendation is in

general for larger deep v vessels.

[PHILRAJOTTE]

no label means tank is not cetified survoyer has to see it so you can get insurance

[LilRichard]

I do believe that they are right... you need a label on the tank for USCG reasons.  Not that anyone will ever stop you for that reason, but here ya go:

[Seadog]

No label - that pretty much sucks!

After you guys had me significantly freaked - I called the manufacturer -

they are making a label for this tank - should have it sometime next week.

THANKS FOR THE HELP!!!

Now got to go change my shorts...

[LilRichard]

Sad thing is I have stumbled across a lot of "do and don't" guidelines, but wonder how much I am missing myself.  Get the boat assembled and run across some law/guideline I have missed.

 :(

[John Jones]

Yes, the fuel fill should be grounded also.

[JimCt]

That USCG info. is interesting.  Glad I read it before starting anything to do with my fuel system.

Link should be made part of an on-line reference library section if we can put one together.
