Paddle Design...Anyone?

I am thinking of building a pirogue for my Dad for Fathers Day.
Does anyone out there have a design for double paddle (a single
paddle will work also) that they would be willing to share?

Does not have to be real fancy, just has to work well.
I will also be trying the Titebond II (yes I will take the boat out
first) for the construction. I will keep the group up to date if I
encounter any problems with the glue.

Thanks,
