I have a pair of cataract oars that are 6.5 feet and were from my old outcast pac 800.... that I would like to use on my Bad Cat 10ft pontoon boat(which came with 7ft oars)

Will the cataracts be safe for the bigger Bad Cat? They are 6 inches shorter and my overall question is...is it safe?...will it effect performance by using a shorter oar?

Any advice would be appreciated.
