Cardboard Boats

[lyntc...@gmail.com]

I have to build a cardboard boat using only cardboard and duct tape.
What kind of shape/design should I use to make it go faster and go
through the water faster? Any building tips would be helpful too. The
paddles must be amde out of cardbaot and duct tape also.

Well, is IS and on-topic request, I guess.

Any takers?

There are whole groups that do this... for the OP, have you tried searching
the net? I know I've seen sites on this. Some places have annual
competitions. I would think a perogie (sp?) style with double (or triple)
layer bottom, double layer sides, and lots of bulkheads. If you could find
boxes used for flowers (and sometimes seafood), they are sometimes wax
coated. I would think that would increase the life in the water.

There was a query like this about a year ago. The consensus was, "use LOTS
of duct tape, and paddle fast!"
The guy did the race, and later reported that the organizers provided a
specific quantity of cardboard and of duct tape -- not enough tape to
waterproof both the outside and inside of his hull.
He rowed like crazy, water came over the gunwales, the cardboard got soaked,
and -- voila -- folding boat. But he had a ball!

We're iced in and I have nothing better to do...

So it seems that it's not necessarily the fastest boat, but the one that
stays afloat the longest, would win this kind of race... So unless this
has to be a "one design" category, the shortest possible vessel with the
highest gunwales would be the ideal design. Divide the tape equally to
cover as much of both the outside and inside of the hull from the keel
up to "waterproof" it as high as possible...if the gunwales get wet and
melt, so what? At least you're still afloat--albeit a bit soggy--and
moving toward the finish a lot longer than if the boat folds up.

Does that make sense...or should I forget boat design and stick to
trouble shooting potty problems?

I don't suppose they'd let you use a foot pump bailer...?

Reminds me of a T shirt I saw -

"I can fix ANYTHING!"
"Where's the duct tape?"

It obviously depends on the rules, but if staying afloat and making progress
towards the finish are the objectives, i'd assume the hull will leak sooner
or later, and ultimately flood. So i'd start with a "frame" which would
preserve a boat-like shape, have some buoyancy and maintain stability with
the "hull" flooded ( and the occupant partly submerged - it would not
attempt to keep him/her dry). Then I'd add panels to make it look like a
boat.

Whilst rolls of cardboard wrapped in tape would have good strength and not
require lots of tape for waterproofing. I suspect they would be difficult to
join. So perhaps a square section wrapped in tape ?

Enough dreaming .....
