well fitted out cruising boat in the 35 to 40 foot range could be $1800.00 to $2500.00 dollars. 300 feet of 3/8 inch chain and your average 45 pound anchor puts a real dent in the pocket. I don't see many boats anchoring on nylon out there. Most boats have chain, 5/16 or 3/8 inch and a lot of it. I still wouldn't go to the trouble of dealing with any of these types of retrievers. I keep diving equipment on board for cleaning the bottom so I can get down if I have to. It's clever stuff but not worth the effort and expense. IMHO
