I didn't use primer at first, but in the low spots (between the bumps) is didn't completely cover unless I double coated it.  As expensive as it is I'd definitely recommend primer first.

Do you use a primer with Kiwigrip?

Jim: It is a very simple and economical design, just 7 sheets of plywood, yields a very practical and stable rig for inland and estuarial waters (think crabbing)  and will be excellent practice for a future and more ambitious build.

Billinoregon - why are you building the short LYSS?  Specific need for a boat that size, or practice for a larger boat?

If you cant find enough noodles at your local store,dollar tree will have them shipped to a local store at 1 dollar a piece,here in florida they are everywhere.

Getting enough flotation into a small boat is sometimes a challenge and since they are hollow, pool noodles are bulky considering the flotation value. You'll also have to put a little more effort in calculating their displacement value. A 2"x48"x96" sheet of rigid foam insulation costs $30 at the hardware store and provides over 300lbs of flotation value. (You get about 60lbs per cubic foot)

If you're boat is rated for more than 2hp, you'll need to distribute the flotation based on the weight and locations of the motor, passengers, batteries, etc. Keep in mind that you don't have to provide a pound of flotation for every pound of cargo and passengers. There are submerged weight factors and you'll need to do some calculations to arrive at the amount of flotation required. Best info is here:

I probably would not use IPE for rub rails because its fairly hard to bend in any thickness.  On a regular Tolman sheer shape,  its probably not as bad to deal with in that area. But Bob you have a lot of hardwoods available. And so laminating a couple of layers makes things a bit easier.  But keep in mind that if you glass your rails along with the decking, you probably do not want the Ipe anywhere near the rails. I would also think that any fancy paint will not stick to it. Now I have XO Rust, the generic Rustoleum on my unglassed but  painted teak rub rails and its no problem. Of course I did prime everything with Kilz you know. ;)

Bob, I've had good luck gluing Ipe.  I've used it on three skiffs now with no issues other than the graphite wearing off where the keel strake hit the polyurethane pad on the trailer crossmember when loading.  The keel strake makes a severe bend as it goes from the fairbody to the top of the bow stem, so I ripped two layers of 3/8" Ipe and glued them on one at a time to accomplish the bend.

I've read on woodenboat about precautions to take when gluing Ipe such as wiping it down with acetone.  I've never done anything beyond gluing and screwing.
