Re: Oil-Canning
Hi Andrew, good to hear from you again,
I like Nels idea of using a water cube for temporary ballast - easy
to adjust and if you are swamped it becomes neutrally buoyant rather
than dead weight. An option for the oil canning might be to laminate
another layer of ply over the area that is flexing. I find the
athwart ship panel joiner in the Mini-Cup to be uncomfortable sitting
and would avoid it if I could.

Great little website! I would strongly advise against adding ballest

prevent the boat from plunging into waves.
So I can see two options. Either move your own weight further forward
in the cockpit and/or add some removable ballest by securing a bag
of sand or a water cube to the spot where your crew would be.
Pounding can also be lessened when sailing by heeling the boat about
10-15 degrees.
short inner keelsons that parallel the exterior keel be more
effecitve. You could even add them to the hull bottom, but they will
tend to also make the boat resist turning.

I've been enjoying my CSD pirogue this summer except for two related
issues.
I experience hull-pounding in light chop, especially when I'm alone
as the bow rises up above the water. When I have my 10-year-old with
me in the forward part of the cockpit, this is reduced. Related to
the pounding, I notice the middle of the 1/4" plywood floor oil-
canning in an alarming way. I've checked the keel strip (1 1/2 X 1
1/2) and it is fine.
I was wondering if adding about 40lbs of ballast weight inside the
forward floatation chamber would be a good idea. My son pointed out
to me that I would need to worry about it shifting to the leeward
side as well.
Additionally, to reduce the oil-canning I was thinking of adding a
cross-piece of 1 1/2 X 1 1/2 athwart the cockpit in the middle.
Am I worrying over nothing, are the things I want to try a good idea,
or is there a better way to fix my "problems".
Thanks
