Today's time was better than any other time I've posted ever, and any time posted on my 12-6 Surftech Bark Competitor. I rested for a few minutes in the channel and then paddled back steady but relaxed, concentrating on what I think is good technique, and paddling about 70% of maximum energy. My overall time was about 1 hour 15 minutes which calculates out to 4.4 mph. Again, a very satisfactory and acceptable time for a board that is not designed for the racing circuit.
At 28.8 pounds the production Shaka is durable and an excellent all-around paddler for rough water, (especially) downwinders, social racing, touring and family activities. An active recreational and fitness paddler could do a race in the morning, a downwinder in the afternoon and then meet the family at the take-out point beach for more family paddling and fun.
For the more serious racer, hopefully Ed and the Angulo movers and shakers will bring the all-carbon Double Shaka to market sooner than later. But my guess is that if an eager paddler wanted to buy one they could get a one-off custom Angulo Double Shaka with just a little bit of arm twisting.
If that's something you're interested in you can get the contact info from the Angulo website.
