Re: PCB on Tennessee vs. Idaho

Actually, The Dakota has considerably more rocker than either Idaho or
Wyoming. It takes relatively low power (50T Yamaha is recommended)
compared to the other two. PCB did draw it with a bilgeboard, but
included a letter with the plans suggesting that the bilgeboard was
probably not worth the time and cost to build. Apparently, there have
been one or more Dakota's built in Australia and those builders reported
that the manueverability was good without the bilgeboard. I did not put
the board in mine. PCB told me that the rocker was to improve behavior
in following seas.

The rocker has another effect also, Seth Macinko and Fritz Funk found in
comparing the performance of their Tennessee and Sneakeasy. This
comparison was somewhat subjective as the two boats are separated by the
North American Continent.

Apparently the Tennessee with its rocker is a much easier boat to handle
than the smaller Sneakeasy. Seth told me he was very pleased with its
maneuverability. Bolger has drawn a centerboard to ease the handling of
both the Dakota and the Wyoming, the big boys of the series, both without
rocker.

Since no one else took this on, I can make a guess.

Idaho's flat fore-to-aft bottom is there to make it faster with more
power; Tennessee's rocker makes it efficient (and slower) with less
power, not more seaworthy.

What makes a boat seaworthy is complicated, and of course involves
more than just rocker. I would just take Bolger's word on it.

Probably, Bolger designed Idaho to be stronger because it takes more
power and goes much faster.

So, as he says, your choice is not one of seaworthiness, but between
economical and slow, and spendy and fast.

Why would IDAHO be stronger given the more extensive superstructure
on Tennessee. Shouldn't Tennessee perform better in rough water do
to its rocker?
