OK, so you guys don't know what sniping is! You will have to learn.
No need to sit there refreshing like a trained monkey until the last second of the bidding process. There are services called "Snipers" -- which offer a free service. You put in the ebay auction item number, tell the program what your top bid is (and you have to make sure it is going higher than any reserve anyone else has put onthe item in question. Then, you tell it how close to the end of an auction you want it to place the bid, and were talking within 10 seconds... then, when the final countdown is proceeding and the numbskull thinks he is going to get your prized widget from your boat for $12, you bid gets zapped in and wins the bid (if your reserver is higher than his) even before he can realize what has happened.
Hopefully you've now left him or her coiled on the floor in a fetal position, biting their fingernails and wetting their pants.
Google "sniper services" to find one. I will ask our director which service he prefers and get back to you. This is not a game... if you have something you need from your boat, or for your boat, you have to have no mercy. Bidding up the price of something just makes the jackass who stole the item from the boat that much richer.
