Jeepers, I never thought of applying that idea to
my own boat! Thanks, Paul :-D
I've sort of been resigned to the fact I'd have to,
indeed, carve foam for the nosecone. I did a double take when you
mentioned "double cylinder". Conceptually I'd never even thought of the
Typhoon in quite that way.
And, yes, I'd intended the ball only for
the mould. Once the scantlings were in, and the f/g layup done, I'd
deflate the ball/weather balloon.
I'd have to bevel the ends of the scantlings
to fair into the ball, maybe wrap the scantlings in a stiff mesh of some sort,
dart the mesh where necessary, and continue the f/glass process around the
ball.
Hmmmm . . .

Yeah, I think so - but just for purposes of building a mold,
right? I was trying to think through your idea of the inflatable ball
and then how to integrate it into your main hull shape - even if your main
hull cross section wasn't circular.
It seemed possible to me
that even if you're doing a Typhoon-type hull (kind of a faired double
cylinder, right?) your ball idea might let you produce a nice, fair nosecone
that blended into the main hull cross section. Maybe you'd need
something more flexible than a workout ball - something like one of those
little weather balloons.
Otherwise to produce a fair, complex plug for
a nosecone I guess you'd look at carving foam? I think that inflatable
ball idea of yours might be a creative shortcut that gives a better result.

Hi, Paul - do you mean strap it into the nose
and build scantlings up to it?
Well, maybe if "Fit Lady" sponsers the
boat.

I wonder if you couldn't constrain the ball with a hoop and
get the proper diameter and shape to fit your hull.
Yeah, you'd
want to avoid having a "Fit Lady" or somesuch, logo on the center of your
nose!
