No, I do not think the floor is more important than the tubes. That is your suggestion, not my view.

I also agree that the Honwave doesn't have a deep vee. I am only comparing a Honwave airfloor to a Suzumar aluminium floor and, of the two, the airfloor Honwave (not the aluminium one) has a more pronounced vee along its entire hull length. The Suzumar with aluminium floor has a slightly sharper vee at entry, but it flattens completely long before the stern.

Thanks for the link, but for info, I have owned boats with deep vee's modified vee's, shallow vee's and catherdral hulls, and I am quite sure I know the difference.

Can we please move on now?

The air floor does not contact the water; the boat's bottom does. The buoyancy is due to the bottom fabric displacing water, not the floor displacing water.

I must add that your analogy about lifejackets didn't reflect what I was saying at all.
Yeah, because you missed my point about buoyancy created by stuff displacing water.

If: the floor, by itself, is buoyant, and having it in the boat adds buoyancy (as you said), then putting lifejackets (which are also buoyant) in the floor of the boat should also add buoyancy (in the same manner you claim the floor does.)

In truth, they don't, because, being inside the shell of the tubes and bottom, they do not displace anything exept air.

We are clearly talking about 2 different products, as the air floor I am discussing DOES contact the water. The Suzumar VIB and the Honwave 380 are examples that have a 1-piece floor/hull. Both have one large high pressure inflatable pad that forms both the floor and the hull, extending beyond the transom to create planing pads. There is no additional skin or shell between the pad and the water.

So, I totally understand your point about the life jackets, I just thought it wasn’t a very good one to make in light of what I was saying. The attached pictures might help convince you that the product exists, as my words alone are clearly going to be twisted into saying that I have some crazy theory about what floats and what doesn’t.

Resurrecting a VERY old post here.

A large, aluminium floor Sib like this, how long to assemble, given practice? And, given the length, would it flex?

Cheers

Simon

It's all about the inflation speed, mate

I have a 365 with alu floor, it takes about 10-15 min to roll it out, inflate a bit the tubes and set the alu floor boards. The rest is down to watever you use to inflate it, your muscles or a electric pump
