Anchor advice

Find grapnel anchor partially closed, and go what a piece of junk! Good thing the chain is holding it, fix anchor and continue dive. Not alcohol induced, but nitrogen narcosis induced hatred for grapnels

I use a folding grapnel anchor and never had a problem with it. I some times use it for diving and it works fine. (I prefer a shot really)

I also use it in boat handling courses and it always comes up intact even when deployed by students.

The Bruce is supposedly the best weight to holding ratio. But the folding Granpnel is good general purpose and of course it folds away saving space in a small boat.

This is a 3mtr Avon RIB we are talking about, not a commercial dive rib or the FFing Titanic, get a grip guys, some of you are losing the plot or have already lost it

I have used a folding anchor with 2m of chain for years with no problems, you just need to know how to set it correctly.

I have just upgraded my boat and have changed the anchor for a folding type, I do have a drag anchor that i need to get rid of, it looks like a plough blade, and is approx 3.5Kg

And this is the post before you self-edited it, where's the three foot high red letters gone?!

[SR4]

Well I am back now, as for the above post re red letters, assumptions are dangerous and it is clear you have made a foolish one and made yourself look daft, speak to the admin team re changing peoples posts

As for everyone else, I want to apologise for my rather sharp last post, it has been a hectic morning but no excuse. I understand that everyone has their own views on this and that, maybe better if each others views were recognised rather than slagging people off for giving advice by disrespecting it and claiming something else is better

I bit and got tangled up in a bun fight, lesson learnt, ignore those that act in this disrespectful way

SR4 - *I* have made a foolish post and made *myself* look daft???! Read some of your own recent posts back to yourself (not just this morning) for goodness sake...

Don't give up do you try growing up

on ships, the anchor does very little (mainly helps to deploy the chain), it's the chain that does most/all of the work. I apply the same principle to my rib. 5m of 10mm chain and it doesn't seem to matter what anchor i have on the end. The grapnel type works fine on my 6.2m rib.

[SR4]

A man with experience thanks for talking complete sense

Hence my initial advice/point of having 2mtr of chain even on a 3mtr light RIB, I left the diameter up to the individual as there is a balance between storage room, weight and getting what works for you

[PeterM]

Or just use a Mircowave, an old air horn and some old lights ....they weigh enough to stop anything actually going anywhere ......

Not exactly, although it does help.

The wieght of the chain causes the anchor shank to lie horizontaly on the seabed, (perticularly with an AC14, Danforth, Admiralty Stockless anchor etc, which then allows the anchor to hold at it's full power, which for a high holding power anchor is typically 1.7 times it's mass. (if i remeber correctly)

If the shank is lifted up from the horizontal, this causes the flukes (pointy bits) to pull out of the sea bed, and cause the anchor to drag.

So yes the chain is important, and is helping, but it is primarily to ensure the anchor is acting horizontally.

Sr4.....can I politely suggest telling people to 'grow up', and implying I am a school child, and have no experience is not really an ideal way to come across as friendly.

Funny posts are just that...bitchy ones are bitchy.

Back to 'lessons' for me ;-)
