Bought a Yetti shell, need lots of advice!

[fishtrapgirl]

I bought a 2014 6.5 x 16' Yetti shell today. Very excited about finishing this house, planning to get a start on it this fall but it will most likely be next summer before it gets completed. Life has gotten very busy for us with a daughter that just turned 2 and also a 2 month old son, so the house is definitely going to take some time. Hoping I can turn to some of you great folks here for lots of advice along the way. My first question right now is we really thought we wanted spray foam insulation in it, however, the house is already insulated with the foam board insulation. What's everyone's thoughts on either leaving it like it is and just spray foaming the floor, or ripping all the foam board out and getting the entire house spray foamed? If we leave it like it is, we can start finishing it now. If we rip out all the foam board, we'd basically just be wasting it as we have no use for the chunks. Plus we 'd have the additional cost of the spray foam. I realize most people will tell me spray foam is the best, but is there really that much difference? Also since we're on the topic of insulation, how many inches thick of spray foam do you recommend for the floor? Thanks in advance for any help you can give me.

I've been close to buying a Yetti shell a few times. I always planned to spray foam over the existing board foam, to cover the faces of the metal studs. They will frost up behind your interior finishings and cause moisture problems without doing that, or using poly.

For the floor, 2" is about all you need. Menard's has the DIY FrothPak on sale through the 29th for a really good price. The 120 may work for you, but the 200 would allow you to go a little thicker.

I have a Yetti and I don't think you'll need to re-do the floor as the sandwich floor seems pretty good. I can walk around in mine with just socks and not get cold feet.

The only ones that have a sandwich floor are the pre-finished houses. When you buy the shell it's just a 3/4" green treated plywood floor. I had mine sprayfoamed underneath, probably close to 2" under there and it stays nice and warm. I thought about doing it myself with one of those kits, but was glad to pay a professional and have it done.

I ran another 3/4" of styrafoam insulation between the fur strips and left the insulation that was already there between the studs. My house has low humidity (at least in the winter it's been 30-50%) and stays nice and toasty with my Atwood forced air furnace. Now my only problem is when the furnace exhaust melts the snow banking and I get cold drafts coming up the holes. That's partially because there wasn't much snow around though.

PM lambjm, I know she built one up from a shell!

im in the same place as you.

-i plan to have the floor spray foam(no sandwich in shell as stated before).

-i was thinking about removing the firing to gain that 1.25" in width for the bed going across.

6'1/2" with firing- paneling ending up being 6'

6'2 3/8" without firing. ending up 6'1 7/8"

i'm 5'11" i think having my head and feet 1/2" from wall could be uncomfortable.

-for paneling i plan to use coroplast. which is a plastic corrugated material similar in construction to cardboard, but rot free.

it has some r-value. does the collective think that frost or condensation on the aluminum studs thru the paneling will be a problem?

-do you recommend cutting in the holes after spraying? or will they protect the catch covers from below?

-how many holes are enough/too much? i can see 8 possible locations. seem like alot in a 6.5'x12"

You're asking for trouble by taking out the furring strips. Huge mistake! I had two enclosed trailers without them and the studs sweated horribly inside and dripped everywhere. Even with your plastic paneling its going to be a problem.

If you know where you want the holes, cut them after insulating. The overspray might get between the cover and trim ring and be a challenge to remove.

6 holes seems like more than enough in a house that size.

I did 6 holes in my 6.5x12, and would do the same thing again. 8 holes seems overkill, I would rather put out a couple tip ups. You will still probably need floor space for coolers, bait buckets, etc. 4 people is pretty cozy for a 6.5x12, I like 2-3 people best if you're going to be out all day/night, and 6 holes is perfect. I have had 6 people while crappie fishing for only a few hours and it was very cozy.

I had my holes cut and covers installled before I had it spray foamed and he just taped over the covers to keep foam from getting on the plastic. Then peeled the tape off afterwards. I'm not sure what you plan on using to cut through the floor, but I used a router with a circle jig.

I am 6' and don't care for sleeping on the bunks in back, but I can make it work. I have the 3/4" fur strips and 5/16" tongue and groove Cedar, so inside dimension is about 6' even. If you curl up at all it's not a problem, but I like to stretch some and just sleep on the 3rd bed instead which I have at 6'4". Make the shorter people sleep on the rear bunks

Never hesitate to ask, there are a bunch of good people here. Not that you don't get some strong opinions sometimes but most are good answers. The search bar on the left, not the top, will get you answers for most things fish house build oriented also. Good luck on the house. You've been here for a while though, you know all that.
