Quick guide for anchoring powerboats



quick guide to anchoring on a small boat we'll look at the anchor system types how much scope to use setting the anchor and asking is our anchored holding or are we dragging going to look at the anchor system now the anchor system isn't just the anchor the anchor system also includes the chain I wrote that we're using sometimes it's all changed sometimes it's a combination of chain and rope and also the shackles that hold everything together so here's the C and here's the seabed going to put an anchor on the seabed and the other part of the system is the chain the chain eeeh actually holds the anchor down it's the weight of the chain that actually holds the boat in place so we want at least 10 meters of chain a few meters would do on a nice sunny day but if your engine is broken and you're being pushed on the rocks you definitely want all that 10 meters of chain so how much chain and or rope are we going to use all together well we take the depth of water and then the total length of chain and rope is going to be at least five times the depth of water so here's some anchors there's lots of kinds of anchors we're going to look at some of the popular ones zonker this like you find on the captain's cap badge this is good for penetrating through weed to find the rock Borriello it's got that cross which angles it around not so good in sand mud or shingle and because of the size doesn't store so well so now let's look at the Delta anchor the Delta anchor is one of these modern anchors got all kind of computer-aided design angles and things on it it's good holding in most conditions the angled flew actually helps to dig in when the anchor cable changes direction because of change of tide or wind not so good to store because reshape it's okay in mud and weed but it's not so good on smooth rock here's another one this is the granel folding anchor because its toes into small spaces it's good for inflatable boats it's good holding on rocks but me do climb everything else it can be thrown onto a vessel that's on fire so you can tow that vessel away from the marina or from an anchorage and it can also be used if you've lost a cable or your friends lost a chain or something on the seabed you control it along the seabed so it's not particularly good all-rounder but it's okayed on on jagged rocks another anchor is this mushroom anchor is called a mushroom anchor because the shape is like a mushroom this is particularly good for a river of honor that's got a muddy bottom on the you know your standard River seabed type thing it doesn't have any sharp edges so it less chance for doing any injury to yourself or to the boat not so good as at sea our rocky bottoms or in weed bankers this is the Bruce Anka is a good all-rounder especially good in mud sand and shingle not so good – Staubach quite a bulky anchor and it's not so good on smooth rock and weed it just doesn't penetrate through the weed another anchor is that damn for basically some angled flat plate and it's hinged to the to the main shaft this is good for sound it's good for murder good for shingle it stores well because it folds flat it's very useful on lot on a smaller boat it's a good all-rounder not so good on flat rocky bottoms especially covered in weed and you need to be careful of your fingers on the hinge system in the anger or laying the anchor on the seabed we need to say to herself where is the wind and where is the tide which is the stronger of the two once we worked out what is the resultant or the major factor we're going to head our boat up towards in that direction heading towards the window tide whichever is stronger so let's look at this on side profile here's our boat we're going to head up towards the wind or tide nice and slow once we got to our anchor position we're going to carefully lower our anchor onto the seabed the chain is going to start laying we need to lay that chain flat along the seabed not in a big pile we want at least ten meters of chain we may use chain all the way through or in this case you can see we've got chain and rope combined the total length is going to be at least at least five times the depth of water how do we find out if we're holding position or if we've been pushed onto the onto the beach here so here's the anchor here's the chain and what we're going to do is we're going to find two objects and you can see here this island and and this island that these two islands they're pretty much in a straight line with our boat so as long as we keep these two in line we're not going to be moved backwards towards the beach so here's some quick top tips use the right anchor type for the seabed use at least 10 meters of chain they the anchor and the cable correctly not in a big pile all maneuvers should be slow and controlled frequently check to verify that you're not dragging your anchor if you want some more information coastal safety calm the force hearing from you you

  1. A very nice video, but perhaps some things have moved on. I've used CQR, Danforth, Bruce, and grapnel anchors, but I've never seen a mushroom anchor in the flesh. A grapnel is suitable only for a RIB or dinghy. The other three can hold well once set, but they don't always set. I now use a Rocna (which always sets first time), with a Bruce or Danforth as a backup or kedge. With a modern anchor like a Rocna, a 4:1 rode is sufficient; and 3:1 will do for a "lunchtime hook". In really bad weather, the rode can be extended, but there's no point ever going longer than 8:1. If you want a swivel on the rode, don't put it on the anchor directly, but a metre or so away from the anchor (to avoid lateral pulls that could snap the swivel). Modern stainless swivels will easily pass through a chain tube. Stainless shackles look nice, but a good quality galvanised one will be stronger. If concerned that the anchor may get stuck, put a tripping line at the back of the anchor. If you have a windlass/capstan (manual or electric), motor the boat towards the anchor; don't use the windlass to pull the boat forward!

  2. 10 meters of chain.. then atleast 5 times the depth… probably don’t need that much … feels bad for whoever has to pull that in if you won’t have a windlass

  3. Most of the sea is really deep though. How much chain do I need to anchor my boat in say 2000 meters of water? Usually I throw it out and just let it dangle and hopw the weight keeps me in the same place. I can't really tell but it doesn't look like the boat moves at all. What should I be doing?

  4. Powerboats or sailboats, we were doing it wrong so it is good to know – and in a couple weeks are posting our video about the time that we had to ABANDON the boat anchor! Sailing has been a huge learning curve so far as we start our journey around the world and videos like this are a great help!

  5. Hi i am a nervous novice with many questions. Feel silly asking but how do you retrieve an anchor correctly and safely manually.

    "One of the best anchoring videos I've seen. I wish the Americans could structure their videos as succinctly as this one. They have good info but always seem to use 100bwirds where 10 will do." How very, very true. North Americans like me tend to pad our videos with "personality" … i.e. "Quippy, Dumb NON-HUMOR." We do this because we want SUBSCRIBERS TO LOVE US—the actual information in the video is completely reticent to the showcasing of the maker's "hilarious" "jokes." It's really embarrassing. AND we tend to go on and on, much like I am right now with this comment. It's a problem. Oh well! Next time! •b18

  7. First off great Video! Well explained. The only thing I would like to add is for when are staying for longer periods of time you will deal with changing winds and tides. I find in a 24 hour period that I end up doing a completed circle around my original "drop zone". With this in mind it is wise to check the area around the "drop zone" as u may end up on the opposite side in the middle of the night.

  8. I’m a novice so I’m gonna ask a very silly question!!
    What happens if the anchor get stuck down below against a rock, cliff,…etc?
    And How often does that actually happen?

  9. interesting.. I came here bc I saw a anchor malfunction video and I realized… i have NO idea how anchors work.. initially i just wanted to know how deep anchors went.. and after watching this video I realized how wrong I was… I thought anchors held the boat bc the anchor went straight down. This makes a lot more sense 🙂

  10. Would have been nice now that we have seen the classroom theory to end off the video with seeing it in action. I would also like to see in real life how the ropes are tied to interact with the chain and how to set that up. I'm a trainer and coach so I am a big believer in theory being followed by a practical then you can start with how to use charts, weather etc to pick the spot to setting up ropes, amount of chain being laid and show how to let anchor out … vertically … and maybe a slight reverse to ensure anchor has taken etc.

  11. One of the best anchoring videos I've seen. I wish the Americans could structure their videos as succinctly as this one. They have good info but always seem to use 100bwirds where 10 will do.

  12. Hi thank you for the accurate description of how to calculate the total rode. Water depth x scope ratio .The USA guides are now incorrectly saying that you should use the bowroller HT to sea bed x the scope! In shallow water this can be double the rode causing all kinds of issues in a tight anchorage. The USA coast guard gives conflicting information in their seamanship guide they say it both ways!
    How do we get this corrected?
    Cheers Warren

  13. Great video, but one thing I find is seldom mentioned is the actual setting… that is, applying reverse throttle to confirm that the anchor has set properly. To me this is a critical step which many new boaters are unaware of.

  15. Hi from your accent you are probably in the UK.
    Hi we have a big problem in the USA, most of the anchoring guides give out bad information about the calculation for correct scope when anchoring.
    The common knowledge for me and in the uk has been to use say 3:1 x the depth of the water. So 30' in 10' depth of water etc.
    But in the USA the advise is to use the water depth plus the bow height x the scope! So with a 10' bow height this becomes 60' of scope in the same anchorage, not a good situation.
    Also a heck of a lot of extra chain to pull in later!
    Perhaps you can clarify this sometime in another post. If you read the USA guides , like boat us , west marine etc. you will be surprised I think
    Cheers Warren.
