Looking for a spreadsheet on seaplane design

Can you look up the name, even better the location, of the person who

All I know about it is in that issue of SA. The author's name on the
article is Neal Willford. The spreadsheet is on the EAA website, and
I''m not a member.

Thanks.

It sorta sounds like you can get the basic spreadsheet and much, much more
for about 40 bucks.

I'm really not just saying that to be a wise guy, or just to push the
membership, and certainly not to get off on some tangent about copyrights.
What really makes it worth the money is that much more. The reason is that
the basic spreadsheet may be awesome, or not worth the paper that you print
it on and, thanks to my own advanced lack of basic knowledge, I couldn't
tell you if I remembered the darned thing.

However, if you even need to ask and you intend to design or even evaluate a
possible purchase, I predict that you will need the additional information
more than the spreadsheed.

Just as one simple example, the shape of the hull and/or floats is generally
asserted to be a major factor in the amount of power needed to get on the
step and airborn, and also in the partially conflicting issues of the water
conditions which might be acceptable...

My basic rule of thumb is that I hit it with a hammer at least once a month.

I'm not sure what that has to do with anything, but what the heck! ;-)

I dunno either, but I try really hard not to do that!

Isn't ones thumb supposed to protect one from striking ones work with
ones hammer?

I don't now about that. The only way I have ever found to never hit your
thumb (or finger) is to always have someone else hold the nail! g

Thanks. That's the one I was thinking about first. The other one
(o612) is the one about hulls, which is what I was really after. I'm
looking for a hull design tool for an airboat idea I found on the
Internet a while back: some guy put a platform, two seats, an engine
and prop on a pair of airplane floats. I was wondering whether it was
as good an idea as it might be; I have no idea whether thing
was .built.

Take the opportunity to join. EAA is a great organization. The monthly
magazine alone is well worth the price.
