1. Does height/length have any effect on safe running speed?

Not that much, there are lots of flybridge boats with the bimini 15
feet off the water. You do need a more rigid frame at high speed
however.

2. 3-bow vs 4-bow - any difference other than looks?

All other things being equal, 4 bows should offer better support and
more rigidity underway.

3. Why don't they make 8' length in the 40-46 height range? Know anybody
who sells some like this?

Any good marine canvas shop can make one to your specifications and it
will probably fit better than an "off the rack" model.

4. If I could find one somewhere (or have one made), would an 8' long, 40"
high bimini look odd (huge and high) on an 18' ski boat?

Sounds a little large but what the heck, it's your boat.

5. I assume Sunbrella is preferable to vinyl?

Yes, Sunbrella is more UV resistant and durable.
