The weather has been rainy, so it's been slow moving but I am making some progress.

I decided that I am going to copy what I did with my Holiday for floatation. First, I span the ribs with corrugated polypropylene sheets. This creates a void for water to move freely, under the sheeting and what will be my foam. The flow allows for easy drainage and hopefully a dryer bilge. It also prevents my floatation foam from being constantly submerged and becoming rotted and waterlogged. After the corrugated sheeting is in, my next step is aluminum floor support framing.

The aluminum floor framing will serve two purposes. One, provide ample support for my coosa decking (coosa is tough but flimsy) and two it will raise my floor 2". The framing I'm using is 2X3. I've been talking to a fabricator and raising the deck 2" is going to give me room for about a 40-gallon belly tank. Once the tank is installed, I can cut my coosa decking. I'm just going to dry fit everything for now. I'm going to have to wait until next Spring or Summer when the weather is right to install my pour-in floatation foam.

other than that I reinstalled my cabin bench framing. I added coosa panels to the bench supports. The coosa panels are what will be the bottom of the new bulkhead. I figure the by adding the coosa now it'll make building and installing the bulkhead easier later, plus that part of the bulkhead extends down into the bilge and having that part be coosa means it will not rot.

Check out the commercial drain grate I picked up. I plan on installing a washdown system and I want the boat to have some pretty serious drainage to handle hosing down the deck should we hook a bleeder.

Winter is always slow for progress. Like the grate. Going to have a catch pan under it in case you wash something you don't want down there?

Yeah, it's getting to the point that I'm going to have to shut it down for the winter pretty soon.

I'm not planning on putting anything under the grates, no pan, no floatation foam, nothing. It'll be open air to the bottom of the boat. The grates will be in-between two ribs, so should something fall in, that shouldn't it'll either be small enough to wash down and end up under the engine, or not and be stuck between the ribs, under the grate. I think the grating almost ensures that the object would be small enough that it would be something that rinses down into the bilge and ends up under the engine. I thought about having a pan or something under them. I don't think it's necessary. It would probably just be something to have fish slime accumulate on and stink. Pans are something that can always, easily be added later if I want.

I got the rest of my corrugated polypropylene sheeting in. I used the HVAC tape to tape it down. I'm happy with the tape on applications like this. It adheres very well and being HVAC tape it has a huge temperature range.

The plates in front of the cabin are for my batteries, two batteries, each side. That'll be 150-300lbs to add to the front of the boat.

The plate in the cabin is for the port a potty.
