I had a few hours last weekend so I made the nesessary cuts in the stringers for routing wires/hoses etc.  I will be working on the boat for 7 straight days starting next week.  More pics to follow.

That has to hurt your feelings to cut those new stringers. Do you glass over the open foam?

I will glass over this Saturday, then install the fuel tank and hoses....bilge pumps and hoses..thru hull transducer, and then the under deck electrical.  My plan is to get everything 100% complete under the deck before I install the deck.

i refer to all the structure in a hull as stringers, regardless of which direction they run.   I cut structure (stringers)  that run in both directions.  Is there a reason you ask?  I will post more pics asap that show the places I removed material.  These are the same places that Panga Marine removes material to route wires, hoses etc...

How did you cut / remove the stringer. Did you use a sawzall?

Good Day Anthony,
FYI, it looks like you setup your Flickr account to allow BB Code sharing.

By clicking on the arrow pointing to the right (located bottom right in picture frame on Flickr), I selected BB Code and then in the Drop Down I selected Large 1024 X 768 then copied and pasted BB Code into the message post pane. Here is what the code looks like and below that the picture itself.

Code:

Flickr's BB Code can be trimmed to only the IMG code and still work. It removes the tag lines that follow the picture. With this example I selected picture size Medium 800 X 600 for reference.

Code:
From this:

I am just leary cutting any stringer and/or bulk braces. Here is a great article to read up on. If Panga Marine is ok with those cuts then I guess you are good, but even drilling through a stinger weakens it. But too, I am not a boat builder either.

Yellowdog...i used a grinder with a cut off wheel and then a sawzall to cut the foam cleanly.

Wildman...It looks like every Panga Marine hull has these same cuts made...they could change their mold and make these changes there too.  If you have seen the size of the stringer system on these little boats you wouldn't be concerned.  Once the deck is adhered the hull/stringers/deck becomes a rigid torsion box, no worries.

Step One - Preparing the tank for installation.  These 1/2 inch thick adhesive backed neoprene strips will protect/isolate the tank from fiberglass below it. 
Step Two - Cut the stringers to allow aluminum L brackets to hold the tank down.  Pics to follow
Step Three - Pour foam around the perimeter to keep the tank from moving laterally. Pics to follow

avitucci : Thanks for posting this, it's some good stuff. This is precisely the kind of detail I was hoping you guys would share on your build projects.  I'm looking forward to seeing how/where you install and plumb the vent and fueling port.

all cuts made;

-2 aft are for the 2 bilge pumps, each discharge on separate side
-3 that cross the middle section are for the 3 aluminum L brackets that will hold the tank down, the bottom of the L brackets will have the same neoprene strips that are on the bottom of the tank and for  the same reason.
-The cut most forward is for the plumbing to be routed aft for the console seat/livewell.  I will also be positioning the console further forward in the boat then Panga Marine does.
-The forward port side (wide one ) is for the fuel fill, fuel overflow, and rigging aft

I sanded the following areas flat in the aft flat section for:
-2 for the bilge pumps, the base plate will be epoxied in place rather then screwed.  when a pump fails, new Rule pumps can be snapped into the old base, if the base breaks or i opt for a larger/different pump, I will grind the old one out and epoxy a new one in.
-1 the one most forward is for the thru hull transducer and backing plate
-2 others for the thru hulls for the live well and wash down

Looks really good, great job ... Lots of detail.  I only have one comment, based on my experience with a 20' super skiff.  The center delta pad is rather concave, I mounted a thru hull transducer in that exact area you are contemplating and I found out that anything above planning speed caught air in that concave area on the bottom of the hull and the sounder lost bottom readings.  I have since installed a transom mounted transducer and can read bottom at full speed, in the right conditions, smooth seas etc.  Likewise, that area might not be a good place to mount your raw water pickups as they might pick up air when you are on plane, get air-locked and quit feeding water to your pumps.
