I needed a top-of-the-line wing paddle. I checked what was available, and I did not want to get one that was built in China with questionable composites. I therefore ended up getting a Bracsa I Min. This is an Olympic paddle.
I have used it to teach wing paddle basics at my kayaking group, Potomac River Paddlers:
I have also used it to enter and win the yearly Potomac River Race run by the USCG and DNR.
The wing paddle's blade size is a hefty 124.9 square inches, and that translates to a huge pull on water for speed.
