Re: A Bigger Brick...?
I added a drawing to photo's under my brick of my modified bigger
brick.I am working on the cardboard model of the drawing have the
hull almost done. I widened the brick by 2' a foot back from center,
legthened it to 16' and narrowed the stern to 30'' and the bow to
15''.The sides are 36'' at the widest part and taper to 18'' in the
bow and 24'' in the stern. The cabin is 18'' above the deck.So far
everything looks good on the model. Looks closer to an AS19.
The thing i'm wondering is if it is to wide maybe 5 1/2 ' or 5' would
be better. I'm going for the most boat I can get under 16 feet with
out a keel ,stable, easy to sail, and capacity to carry 2 or 3 with
gear for a weekend.
The drawing is not to scale it was done on my paint program.

You could stretch a Brick OK, after all it's hardly a delicate, refined
design. <g> But there's already a design very much like what you want to
end up with:
http://groups.yahoo.com/group/MessaboutW/files/BoatPlans/SucherScow.gif
A 13' 6" scow from Harry V. Sucher's book Simplified Boatbuilding. Plans
are available also from the Smithsonian for $10, plus shipping. HVS/FB-002
plates 4-197 & 5-199.

Hi -
I have a couple of rambles to "contribute."
BRICK exists as an answer to the question: "how much boat can be made
with 2 sheets of 1/4" plywood?". That is its purpose.
Each of the design questions you pose has an answer - perhaps answered
only by trial and error. If your underlying question is along the
lines of "I simply wonder what will happen if I do thus and so to a
BRICK regardless of whether or not it will end up meeting my
needs...?" then I say go for it. If we knew what we were doing it
would not be called research. I am all for experimenting for its own
sake.
Entertain, though, the possibility that maybe you need to be asking a
different question. Maybe the question is really "my wish list is
this and that, what is the best design for the purpose?" If that is
the case, then maybe going with a proven design like JUNE BUG (longer,
decked ends, etc) is in fact your answer.
My thoughts!
I hope you post photos of whatever you end up buil

bet that all the rigs would work just fine. The 59sqft I had was just
right, so you could probably upsize a bit without making it too unruley.

one and find out? The brick is the easiest of all to build, bet you
could probably have a hull put together in 1 weekend.

Any advice on your questions on my part would be pure guess work, so I won't
give any on that. I will however strongly advise building a scale model with
any of the changes that you are wanting. That way you will be able to see
how they work, or if they work.

Thinking about building a bigger Bolger Brick. Just a couple more
sheets of ply with careful scarfing and I'd have working pieces 12'
long. So a Brick about 11+ or so feet would emerge. Plan to keep her
4 foot beam, just lengthen somewhat.
Opinions on the following, please...
First, simply duplicating larger the existing curve of the bottom
rockerwould make her a bit deeper, so I'm thinking of softening (i.e.
flattening the bottom rocker just a little. Any thoughts on the
adviseability/risk of that?
Second, with the added length, I could deck fore and aft and add
flotation underneath and enclose. Maybe lso have some secure
stowage, andstill have at least a 4' x 8' "cockpit".
Third, I prefer a centerline spar. Thinking about mounting it at the
after end of the forward deck, more catboat style. How do we think
she'd do with a sprit sail? How about a lug? I also have a rig from
an old Super Snark in excellent condition -- a stripy lateen thing
about 60 square feet.Big enough? Where should the center of effort go
on that boat (at hernew length, that is). X% aft of the CG? Any
guesses that make sense?
Finally, would an aft skeg make sense? Might help her track better.
Here's a weird idea -- what about a box keel right about where an aft
skeg would go, about 18" wide. My thinking (or lack of it!!!) suggests
that such a structure wouldn't much impede her ability to sail, but
might just be enough of a surface to let her plane with an outboard on
her stern. Kind of a permanent trim tab. Well, I said it was weird...
Would appreciate constructive criticism. I get enough of the other
from my wife.
