A ground anchor fitted to your garage or driveway with a high quality padlock and chain is an excellent form of security for both jetskis and trailer boats.   

There is a wide selection of anchors on the market, which can be bought at most motorcycle accessory shops or here on ebay.  

Our advise is that the type of anchor which get buried in to the concrete offer a greater resistance than bolt down anchors as they have no bolts heads to sheer off and have no parts showing to encounter attack.
