[rebel-builders] RE: External Load Carrying - Canoe on Rebe

[Garry]

In the book "Water Flying Concepts' by Dale De Remer on page 8-5 he
states 'Blunt ends of objects should be faced into the airflow, pointing
forward. In other words, a canoe with a transom for mounting a motor
must be attached with the transom facing forward.'

Wayne has already proved the workability of this method on the Rebel.
Thank-you Wayne. If anyone else wants to experiment with other methods,
looking into the written lore would be a good direction to start in.

Which way does the blunt end of a steamline strut face Ben???..and the
pointy end?

I'm not sure I buy the comparison. The strut has smooth corners on the
front edge. The canoe has hard corners which would make turbulence and
eddies making a larger effective frontal area and drag. It's true there
would be eddies on the trailing side of a square corner thing too, but I
still think the eddies and drag would be less. I'd also guess the
stability would be better (yaw and pitch) with the pointy end at the front,
but heck, you've already found it to be a non issue.

That was another myth I was always told... the real reason apparently is it
can't slip out thru the straps if the narrow end is at the back! lol

Now this one, yeah, I'm with ya there!

Impressive that the Rebel hardly cares about that big thing on there. Why
did you face the canoe backward instead of forward? Seems drag would be
slightly less with that transom in the back.

Anyway, it's a pretty sight and one more great thing to look forward to.
So Thanks!!
