Race where I’d be lumped in with them in my 22’ CD Libra XT
Other option is Extreme over 18’ so against surf ski’s that I know is definitely not good.
I assume canoe tandem should be fairly faster than my Libra unless it was rough. 2.5 or 5 mile races.
Canoes of comparable style, a tandem will be faster. But a fast solo can be faster than a slow tandem depending on the paddlers.
Thanks my tandem is about 5.5 or 6 maybe if it was real rough. Oh well back to the drawing board.
Is there a hull width requirement in the tandem canoe class you are entering? Most rec canoe classes have a max length of 18’6" require the hull to be proportional to keep out skinny boats. In a 22’ boat, I take it you would be in some sort of unlimited class in which case you might be at a disadvantage if there are a lot of true racing boats in the mix.
Libra XT tandem 22’ x 32" only hope would be rough water.
What are the rules in the class you would enter it in? Since your boat is 22’ I am assuming is an unlimited class of some sort, so if you have two paddlers and use double blade paddles you could be competitive. If there are a lot of real racing boats in the class though not so much. Some times its better to go small and run in a rec kayak class rather than have to be in there with the big dogs.
Can’t enter my CD Extreme at 18’-8" I’d be in with surf ski’s. Possibly my Solstice 17’-6 in kayak class.
Looking at it now can’t have a tandem bigger than 17’
Well, if you could find a Jensen 17’ you would problem smoke them. Distances are pretty close to a sprint for C2 marathon paddlers.
Winning time for the AuSable marathon tends to close to 14 hours. That’s an average of almost 8.5 mph for the 14+ hours. Maybe 60% moving water.
Nothing I own will do 8.5 mph even in sprint mode and it wouldn’t be for 2.5 miles my heart 
would be on the deck. Regular kayak class may be the best choice 18’ or less I’d use my CD Solstice GT.
Age classes should help me at 68 LOL
