depends on how deep the water is :-)


I have about 40Mtr on My rib with the ability of adding in a further 60 if needed
My anchor is light but does the trick.

And it does depend on how deep the water is. if your in 60Mtr of water with 40Mtr or anchor and rope your not going to hit the bottom.

but for costal in shore I think 30mtr to 40mtr would be fine. worked for me and my rib.

In theory the general recomended ratio for boats are approx, ,,, chain only 3 x depth
,, rope only 5x depth.


but most of these calulations were made many years ago in Victorian times , in gale force conditions using deep heavy displacement hulled sailing boats using the common Admiralty /fishermans type of anchor ,
i am not saying there wrong but light planning craft of today using high hold type anchors and thinner high stretch modern man made ropes perhaps dont need as much ,
minimum i take is 30 mtrs , a lot also depends on the area your operating in ,
best be safe and take along more rather than less .

Same here, grapnel folding anchors are ideal for SIBs.

I own a folding grapnel anchor for my kayak and would never consider it for my boat. They "FOLD" and often when you don't want them too. I need my boat to be waiting for me at the surface.

My preference is for a Bruce or Danforth style anchor. I have a Danforth.

Since we often anchor in 30 meters (100ft) of water, we carry 97 meters (320ft) of rope, with 4.5 meters (15ft) of chain. Everything packs cleanly into a milk crate mounted in the bow. Since I boat with other people I also like the anchor line markers for length. Super easy to say, "put out 120ft" and they can find the marker labeled as such. The end of the anchor line is also tied into the milk crate to keep stupid from happening.



Curious if others do something similar as below? Or where do you tie your anchor off too?

The tow bridle in the front was built for anchoring so there are always two points of contact on the boat. Hence why it also has a knot in the front for the carabiner to pass thru in case one side breaks loose it won't slip away.
