Zip Floor

Post by jthurber »

I am just past the Zip flip and studying the plans for next steps. On considering the floor, it appears to me that if I follow the frame height, laying the floor even with frames 2, 4, and 5 1/2, the floor will be going uphill toward the bow. Was this a drainage consideration for solid flooring? Am I looking at this wrong?

I will fit my floor with the top surface flush with the top of frames 2 and 4. Frame 5 1/2 is higher than that, as you observe. I will keep the floor flat to 5 1/2 and let the frame protrude above it. The design is to do with structural considerations, not drainage.

Flat but not really level, right? Since frame 4 was notched into the setup/building frame...

Yes, I realised that after I'd replied. But level is the way to go to my mind - who wants a sloping floor? Frame 4 will likely be under the front seats or bridge deck depending upon the layout you choose (I can't remember off-hand) so having it higher than the floor won't be a big deal.

In my defense.... whatever. I know frame 4 is the dash frame on a regular Zip. So the base member of the frame is under the front seat passengers' knees or perhaps slightly further forward. If you sloped the floors up to it you would either raise the seats higher than would be ideal or you'd have less space for seat construction.

All excellent points. The plans seem to show the front cockpit floor level with frame four and blocked up accordingly at frame two. The rear floor is shown lower. I also want my front seat to be as low as possible so I’ll likely do what you suggest and leave frame four sticking up above the floor. Thanks for your replies!

Your feet will extend beyond frame 4. I didn't put flooring beyond that. Rather just placed removeable carpet on the bottom for my feet. I recommend putting the seat frames on sub floor planks athwart ship to keep seat height lower. Zips have very little free board and will make you feel a little high in the saddle. I also made removable floor grates that naturally drained water into the bilge.

Thanks Roberta! Did the top of your floor end up lower than frame 4 then? Is it a nuisance to have a bit of the frame sticking up?

My flooring was fully removable as were the seats. I used spreaders to support the seat bases and floor grids. a blocking ledge was attached to the aft of frame 4 to support the grids. Plywood ledges were made to support the seat bottoms and blind nuts were attached to the bottoms to allow the seat bases to be bolted in. Floor grids were made from scrap pieces of mahogany. Here are some pics of the spreaders and other seat supports and the grids.

The floor grids are just set in place with the frame or blocking keeping them in place. The flooring and seats were removable to be able to get to the sole of the boat for any possible future repairs in the bilge area or other work. The grids are about an inch below the top of the frame 4 bottom member. Stepping into the boat is done by stepping the seat cushions and then the floor. I put a foot rest bar in front of frame 4 and no additional flooring, just the carpet mentioned earlier.

I opted to run my floor slats side to side. I used 3 floor battens per side and attached vertical strong backs on top of the battens. My floor slats rested on those strong backs. With roughly 6" between battens I could use 5/16" thick floor slats. This made the top of the floor about 3 1/2" below the top of the dash bottom frame member in the center, and where the floor slats met the hull they rested on the chine.

Compared to extra sub framing and thicker floor boards required for a 'conventional' floor this let me significantly reduce the finished weight of my ZIP. It also let me set my seats lower so that I actually sat down in my ZIP. The slats also let the bottom of the boat 'breathe. If you look for 'live' shots of ZIPs you will see how most folks are sitting high up.

I like that idea, thanks! I am fairly tall and would like to be sitting lower. This looks like a good solution!

The cabin sole for the Tahoe is on top of the engine stringers. It seems very shallow. I lowered the sole 2" between the stringers. It makes a much more comfortable position and the cockpit feel much larger.

Roberta, I had not notice the 2 cat food dishes in the back of your Zip before.
