Count me in. I'm new to NSPN, so I should describe my experience level. I have been paddling for about 20 years, class I-V white water, I paddle my Necky Elaho mostly on the Charles River 3 to 4 times/week averaging 4.5 to 5.2 mph for 4-6 miles, so paddling the distance in the conditions you describe is no problem. I have a very solid roll.
