Have a couple of inflatable Sevlor kayaks aboard, a one person and a two person, good quality construction, durable
fabric cover, paddle surprisingly well for inflatables. Easy to store of course is one of their best features.
Ebay is a great way to get rid of excess
boat junk. I was selling some years ago and was not making enough progress selling one item at a time. So, I started filling small boxes with lots of miscellaneous boat stuff --- I was quite surprised how well these
sold.
An interesting eBay phenomena, people get caught up in the thrill of the chase and I have had many used items sell at near the near their new retail
price. I've even had a couple sell for MORE than their new retail price! What are these people thinking? You can capitalize on this by structuring your listing so that people are encouraged to make that first bit. After a few bids you get a feeding frenzy going. What has worked for me, is to list the item with a very low starting bid and for higher value items set a reserve
price. This way people can start with a low bid and get the frenzy going.
Good Luck.
