Re: anchor weight required
I have been useing the Fortress FX-7 for over 10 years on My 21 foot runabout. I got it at first for the Wife. She does not like to drive the boat up to the anchor to pull when it foggy with strong winds and current, she would rather I drive and she pulls. The problem is she is not strong enough to pull the 8 Pound Danforth, she gets it off the bottom and up about 10 feet and she totally worn out.
So I bought the Fortress FX-7 and 4 feet of chain. First trip up to a local lake where it was always hard to get the Danforth to dig in and set but the fortress set without draging at all. The old danforth sometimes we would try several times and it would just drag the bottom and not set.
After a few trips with the Fortress I removed the 4 foot of chain and it stillsets with out dragging.
The Frotress flutes are sharpened on the end and as soon as it hit's bottom in grabs and diggs in without dragging. Also the shank is thinner and longer and will bury in the sand just like the flutes. Old anchor would often drag untill the flutes went under a rock or a fallen tree or bush. This then would make it very hard to pull up and the end of the day. Also the old Galvanized anchor had drug on the bottom enough to sand some of the Galvanizing off and woud try to rust.
The Frotress is Anodized Aluminum Magnesium Alloy and over twice as stoung as steel per pound. It will not rust and is the best anchor i have ever used.
Check the testimonials and the anchor test at there site. Also the facts and myths.
