Canoe and kayak molds were (are?) frequently owned and loaned by clubs. Some clubs offer free use of the molds with membership, while others rent the molds to memebers at a good rate, and store them between use.

You might want to see if there are any local clubs which might be interested, as shipping these things any distance is as expensive, or more expensive, than shiping a complete boat.

Or, you might place an ad in a kayak magazine offering to rent or sell these.

E-bay is another option if you want to get these into the hands of an interested person.

good luck with this.
