No closed off compartments or sections to hold water. No carpet. Should be easy to wash down. Desire to have top wot, w 2 adults and gear of 25MPH. No livewell required, but should have space planing for a removable cooler style (very rare), or airated minnow bucket.

Your budget is light...especially for electrical.

Yea, trying to be aggressive there. I do have allot of the materials on hand. I should have most of the wire and connectors, and sheath. I do need a new panel though.

Three 4x8 sheets of aluminum and one 4x8 ext plywood, plus bedliner type paint takes the biggest chunk. The misc stuff does add up quick though.

If I actually come in at a grand, will be happy!
 
Got her in the garage and all the mechanical items removed, this evening.

Looks like, for my floor/sides, I need:

- Two 4' X 8' X 1.5" sheets of foam
- Two 4' X 8' X 0.040" sheets of aluminum or (one 4' X 10' and one 4' X 8' for a no seam floor)
- Two 10' X 1.5" X 1.5" X 1/8" Alum angle
 
I have never once in my life taken the time to plan out a project like this, I always end up buying things willy nilly, changing everything as I go along, and spending far more than anyone (wife) planned! 8)

I will be following!
 
Back from the store. Not the best day to be buying large wind catching items ;)

2 - 1/2" x 4' X 8' ACX = $65
2 - 1.5" X 4' X 8' Styrofoam (blue) = $63
2 - 0.040" X 4' X 10' Alum Sheet = $163
Cut and bend one sheet, no charge

Total: $291 or about half my materials budget! :D


I did my last boat with much less planning, but think there are allot of projects here that have me beat! I kinda plan the high level stuff, and then work out the details as I go. :)
 
Cleaned the boat out and cut the foam to the floor width. Most were 12" wide, with one 11.5" and another 12.5". Cut with a dull hacksaw blade.

OK, I have to figure out the main wiring before I can put the sides on. Here is what I came up with:

JonboatlayoutElecA.jpg



Circuit #1: Bow FF / Nav Light, 16ga wire, 3A inline fuse (nav light is a tall plug-in to get over the trolling motor)
Circuit #2: Trolling Motor, 8ga wire, 40A manual reset breaker
Circuit #3: Engine, 6ga wire, 50A manual reset breaker
Circuit #4: Electrical Panel, 10ga wire, 30A manual reset breaker

Circuit Panel: 6 gang
- Anchor Light
- Bilge Pump
- Stearn FF
- LED Lighting
- Aux 1
- Aux 2
 
1st Delemma:

While the ribs are 1.5" high and the insulation is 1.5" thick, the foam is riding higher. This is becase the foam sits on the rib flange. This is aout 3/32". The difference in height will be noticeable over time, as the alum cold rolls, from walking over it.

NOTE: Measured crossbeam material thickness with calipers: 0.100", or a little more than my estimate of 3/32".

Possible solutions:

- Cut all the foam blocks back, allowing flat surface.

- Run a caulk bead down each rib before installing sheets.

- Find something that is 1.5" W X 3/32 thick, and apply to all ribs. Also could lay under foam for a slight gap for water drainage. I like this thought the best, so far, if I could find some that is cheap and easy to apply.

I have decided to take the extra 10' X 15" alum sheet back to have in cut into 3" strips, and bent at 90 degree angle. I'll use this for the top cap of the side panels instead of angle alum.



PS: A couple of ribs have some weld that needs to be ground down.
 
looking good so far, I have to keep an eye on this build as I'm planning on doing something similar. What are you using the ply wood for?
 
Plywood is for the front and rear decks, along with a box for mid-seat, and rear deck compartments. Two sheets plus the scrap I have "should" be enough.

Busy work week, with travel. Hope to get the alum floor/sides done this coming weekend.
 
I was faced with the same problem when fitting my foam in the floor and the rib rivets held the foam up. After getting all my pieces cut to size, I made a few quick cuts with the table saw and removed ¾" wide by ¼" deep around the bottom side edge of the bottom piece of foam. Pic's removed so it doesn't clutter up your build thread.

I agree. having done marine wiring for the last 15 years and also having been involved in insurance claims where shoddy work and cheap materials and in some cases just an unfortunate "Aw, S**t" were the cause of a boat fire, I can tell you that this is not where you want to skimp. Marine wiring is subject to a lot of vibration and mechanical stress and strange things can happen. This is where you want to use stranded pretinned marine wire, quality connectors and adhesive line heat shrink. Go to this link, https://www.paneltronics.com/ip.asp?op=Tech_ABYC and download the two PDFs. They are excerpts from the latest ABYC manual on marine wiring and they are free. Fuse and circuit breaker protection is very important, not only from a size standpoint, but also location. You can't know too much about this stuff and you can never know it all.
 
Progress, slower than expected :(

- Ran 1/2" PVC down both sides to use as conduit for the main power wires. I was unable to do as one continuous piece (too tight between the ribs). Ran short pieces behind each rib, and then cut to fit for the rest. Ran snake wires down each to pull the fish tape through.

- Drilled small drain holes, three on each side of the ribs to allow draining down the center.

- Ground the few welds down to make sure they will not deform the sheet metal.

- Vacuumed out the shavings and debris.

- Did final foor drain rib washdown. Added some bleach to the water to kill any mold, etc where I can't scrub. Rinsed out. New drain holes seem to be working.

- I am using stick-on vynel floor tile for my spacing. It is slightly less than the alum thickness, but should be close enough. Ten 12" squares, cut into 1.5" stips. Stacked and cut with skill saw.

It needs to warm up a little bit so I can put JB Weld in the crossbeam divots.

Golf Club Tubes will be used for the under deck part of the rod holders.
