Re: [bolger] Re: Square Two Sheet Skiff

I agree with your characterization, but it doesn't get
the makers of these arguments anywhere unless they put
numbers on it, and then the results are different. If
one had a 6 foot on deck boat ,and tapered the sides
to 5.5 at the WL would it be dried than a higher
riding identical boat that was six all the way down?
When people make these arguments they always assume
the flare/plumb cuts their way. Where more stability,
more seaworthy, or spray reducing arguments are
concerned, usualy more volume trumps. So if you grab
more volume by flairing the sides, or moving out the
waterline you usualy win. Technicaly, if your plumb
sided boat was as wide at its widest point as the
flaired boat, if would have both higher initial, and
secondary bouyancy, dependant on other factors that
might or might not translate into a larger righting
moment.

Then you get into the economic arguments, and they are
all over the map.

 
Plumb sides offer more initial stability but less
reserve stability 
given similar beam and freeboard. Traditionally,
the knock on them 
was that they'd be fine until they heeled over to a
certain point, 
then they'd abruptly fall over and stay there.
Properly constructed 
and operated plumb-sided Bolgerish sharpies have
higher freeboard 
and a lower CG, giving them plenty of reserve
stability unless you 
do something stupid (such as mounting a diesel
generator up on deck 
on an AS29).

Paradox has a 
range of stability of 165 degrees!)

What's wrong with "Bolgerbabes?"

Subject: [bolger] Square Two Sheet Skiff

Bolgermen and Bolgerbabes,

Some time ago there was a thread about Junebug. A great deal of the
discussion was testimony as to how stable she is. Builders talked about
being
able to lean over the side, climb in and out of her, etc. The boat was
designed to be as stable as possible within the smallest dimensions.

I assume this stability is due to Junebug's square sides. Yet all the
literature about skiffs, including the Pointy Skiff, shows boats with flared

sides. There must be virtues to both. I think maybe the flared hull is
prettier and drier. But the square sided version is a more stable platform?

Anyway, I had an abandoned project sitting out in the backyard for a year or

more and decided to resurrect it. I took it apart and recut the sides and
used some bulkheads I had made up and glued it all together. The result is a

square shaped hull just under 8' long and 39" at the beam. The transom is
30"
and the bow is pointed. To get the chine log on I'm going to have to kerf
it.

I'm eager to see how this little two sheet skiff behaves once I get her in
the water. Anybody have any thoughts about it?

When the June Bug was first published in Small Boat Journal, its plumb sides
kicked off quite a discussion. Dynamite Payson in one of his books, and if
I remember correctly in the Journal itself ,said sometbhing like he could
get just as wet and drowned by falling overboard from a plumb sided boat as
from a dory. I suggest you look up this discussion- good reading about
plumb sides vs dories, etc.

I think it is somewhat semantic, as folks argue about
the most boat you can get for a given plan shape at
either the shear or the chine. What can't be argued
is that plum sided boats can be tucked in closer to
the mother ship for stepping into, and are more stable
when you lean over the side for some purpose like
hauling traps.
