Oarboard SUP Rower is a sliding-rigger device that can be attached to any standup-paddleboard to enable a full rowing experience. Have taken out many times in Galveston even in heavy surf it performs well. In excellent condition.
Also can include Concept 2 collapsible carbon fiber oars for an additional $495.
If you need a paddleboard, and these are solid ones not the flimsy inflatable kind, I have a beginnwr stable foam 12' board for $295 and a fiberglass racing Naish 17' board for $895.
