Hey Mech, I am also relatively new to the sport and currently paddle a V8. I don't paddle the ocean. All of my paddling is flat-water done in a circular protected bay in New York known as Jamaica Bay. The bay has front and back bays. It has a 25 mile perimeter and for the most part all of my paddles are large circles, so I run into varying conditions along the way. Most times the water has a max chop of about 2 1/2 feet with 1 foot and under the most common.
I like to describe my paddling style as sport-touring. I try to fitness paddle 50 to a high of just under a 100 miles a week. I have owned my V8 for just short of a year.
Before that I, for the most part, paddled a South African fishing ski made by Kaskazi, a 65 pound boat that is 25" x 15'8".
I tried to post a snippet of a few days I recently logged on my Garmin, but can't seem to get them to load.
I haven't downloaded my most recent outings but these numbers should give you some info to use as a guideline.
I'm in my early 50's - 5'9 195. I alternate the use of a Onno Large Sprint Wing and his new blade that is sized in between his Sprint Wing and his Mid-Wing.
Dates 6/5, 6/6, 6/7
On 6/5 I paddled 16.65 miles at an average of 5.1 mph max speed 7.5 mph. (11.49 per mile) Winds were 17mph with gusts just over 20.
On 6/6 I paddled 17.4 miles with an average speed of 5.7 mph max speed 8.1 (10:30 per mile) Winds were under 10mph
On 6/7 I paddled 21.44 miles with an average speed of 5.6 mph max speed 8.1( 10:42 per mile) Winds were under 10mph
The fastest average I have ever had was 6.2 - 6.4 mph over a distance of just over 8 miles, on a few perfect, cool, spring mornings.
For me personally, the most accurate -overall average- taken over the course of a month, where conditions on the water vary a great deal, probably runs between 5.1mph and 5.4 mph.
All of the averages above also include periodic stops to drink water out of squirt bottles. I carry three 27 ounce insulated Polar bottles with me. I keep two in front of the foot plate held by a bungee and one in the stock holder. I also usually stop to grab a quick energy snack out of the bag I keep on the back of the boat.
My top speed just about every paddle runs between 7.1 and 8.4 mph in short bursts of 1/4 mile or so...
I have in calm conditions, carried over 6.8 to 7.5 mph for a mile plus distance, with a slow moving tide beneath me and calm winds.
The boat for me seems to top out at in the low 8's.
The fastest I ever clocked in the boat was 12.1 in strong inlet current when I was surprised by a 5-6 ft wake from a large yacht that came up behind me. Now don't get me wrong... No way did I intend to ride that wake and that speed lasted for about ten seconds causing my eyeballs to bulge Wylie Coyote like, outta my head.
Hope this info is helpful.
