I would think to start them on e-bay for around $400 each and see where they go from there. The right buyer may pay more but finding the right buyer is the trick. I sold a similar boat with a higher level of workmanship (though no electrics) here on the market place for $500 -

While winter months are a little slower for selling - it is also the time of year when Dads shop for their own Xmas presents!!
You might try listing them on the RCU Marketplace - it is free to list and no fees if it sells.
