I putting running lights/reflectors on mine.

I figure it might be worth it since it's more of a 'voyaging' craft, even if I don't have the SailRig on it.

The only downside is that the lights I got are a little oversized, I'm hoping the fact that is being 19.5 feet long will take the emphasis of the lights during the day.

How about reflectors on the ends of the paddles?

It's a good idea to reenforce the tips anyways...
