Re: Mantus Anchors NEWS: anchor sizing tool

Having the three size options is a good thing IMHO. As for me, I use a lunch/race hook most of the time up front! vs the heavier cruise hook. Probably since I race more than cruise and anchor out........just trying to make the grade with the race rules one has to follow.

For some of you that have not seen at least my local minimum anchor sizing.
(LOA/17)^3..... so for me (30/17)^3 = 1.765x1.765x1.765 = 5.49 ls of min anchor.
Total anchor rode etc is (loa^2)/80.......(30^2)/80 = 900/80= 11.25 lbs of anchor, chain and line. Min length of rode is 150'!
I have a 9lb fastset, 6' of 3/8BBB and 200' of 7/16" 3st.

The other I like in the options. the cruise anchor has a recomended chain size, in both std and hi-test. along with a min rope size. It would also be interesting to see the min option for a lunch/storm potential option too. Or better yet. Lunch is good to say 20knots of wind, cruise to 40, storm to 60, SUPER storm to 80-90 knots!

My recomended sizes were 13, 25 and 35. I have the 9 and a REAL 16.5 bruce! Even says made in belgum! I'd personally feel a bit better with a 10KG/20-25lb anchor and 30-50' of chain vs the 15" of chain I have. 5/16 vs 1/4 that I have. Rope size is plenty at 5/8" for a 30' LOA 7K boat.

I drives me dinghy!
