In addition to local San Diego demo boards, we occasionally get returned and exchanged paddle boards that have been used. Typically, we batch test and process them for grab bag sales we do a few times a year. We blast out what's available to our email list and they typically sell out within a few hours. We've sold 60 used paddle boards in under an hour before. It's a great deal for customers and it helps us clear out any returns from the warehouse to keep things tidy.
Between these larger grab bag sales on used paddle boards, we periodically list used paddleboards for sale here. Our stock varies, so check back here. Don't bother calling us, as if we have used boards available they're be live on the site here or you will hear about it via our email list (you can sign up at the bottom of any website page).
There are two classes of used stand up paddle boards that we typically receive and resell, and a third class of used sup board that we won't even sell. If a used SUP board has a blown seam or is in really bad shape, we just toss it in the dumpster. While inflatable paddle boards are extremely durable, they can be severely damaged with improper inflation with say an industrial air compressor, so at some point a few used stand up paddle boards become not worth fixing.
The other two classes of used paddleboards that we do sell are:
At Tower, we've got a pretty generous return policy on used paddle boards. If our customers are unhappy with their purchase, we typically accept the boards back. So sometimes the SUP boards have been used extensively and come back and sometimes you couldn't even tell it was a used stand up paddle board... it's literally unwrapped in the original packaging and the customer just changed their mind. Regardless, if a paddle board has previously been sold, we mark it as a used paddle board for sale. These are incredible deals when you can find them and that's why our grab bag sales sell out in just hours.
If you get a tested (and passed) used paddle board, it's not going to require any repair at all. It's basically just dirty (and sometimes not even that) but otherwise a brand new iSUP.
If you purchase a used inflatable paddle board that has been marked as "requires repair", these can typically be fixed with a simple paddleboard accessories patch kit.
