How to Choose Your Anchor

Choosing the Right Anchor

Choosing the right anchor for your boat is not a complicated task, however, you need to appreciate a few characteristics before deciding which anchor is the best for you and your boat.


Here are some of the important questions you have to ask yourself before starting the voyage:

  1. What boat will it be mounted on? Motor or sailing boat? Usually, sailing vessels require more holding power than motor vessels.
  2. What is the size and weight of the boat that the anchor will be used for?
  3. In what conditions are you sailing? Do you only sail at weekends when the weather is good or do you sail - and need to take what comes
  4. Are you sailing with some, children, who might have difficulties in handling heavyweights but who you want to include in all activities on the water or is it a professional crew made up of rugby players and weight lifters.?


In the charts below, you will find answers to the first 3 questions above but the fourth one needs to be figured out by yourself.

Because our anchors are much lighter than other anchors for the same hold we offer you the opportunity to ‘oversize’.   You still have more than sufficient hold and know that our anchors are at least as strong as the other options you might consider..  Our hold data is conservative, we have looked at the worst-case scenario.  We have not quoted average hold but have introduced a safety factor.



Let's start choosing your next anchor.


The following chart gives you the amount of holding power your boat needs.

These values were formed by the American Boat and Yacht Council (ABYC) and they are conservative and include worst-case scenarios.  1 Kilo equals 2.2 lb



WIND SPEED           15 KNOTS        30 KNOTS         42 KNOTS

LOA 35 FEET          225 pounds       900 pounds    1,800 pounds

LOA 40 FEET          300 pounds    1,200 pounds    2,400 pounds

LOA 50 FEET          400 pounds    1,600 pounds    3,200 pounds


This chart shows the maximum holding power for each Viking anchor model, tested and measured in a sandy seabed.

All Viking anchor models had been tested to measure their holding power. Since holding is greatly affected by the seabed type, we conducted our testings in the same seabed condition which is sand. Your holding power will vary, depending on the seabed in which you might choose to anchor.  This is why we cautiously write in our tables "Estimated holding power


Model Estimated Holding power Kg Estimated Holding power Lib.
Viking 5 500 Kg 1,100 Lb.
Viking 7 900 Kg 1,980 Lb.
Viking 10 1,900 Kg 4,180 Lb.
Viking 15 2,600 Kg 5,720 Lb.
Viking 20 3,200 Kg 7,040 Lb.
Viking 25 4,500 Kg 9,900 Lb.
Viking 30 not tested not tested
Viking 35 not tested not tested




These three charts show what Viking Anchor model can be used on which size and weight of SAILBOAT.

Normally motorboats need less holding power comparing to monohull sailing boats, sailing catamaran needs more holding power.

Meaning that motorboats will need a smaller anchor and sailing catamarans will require a bigger one.

As you can see, there are a few options for every boat. For example, Viking 25 will hold a boat up to 25 meters (80 ft.) but it will not be wise to use it on an eight-meter boat. Therefore, please spend some time answering the questions above before deciding.

We advise using the recommended size anchor for your boat size, upsizing is "just to be safe" can be done but there is absolutely no need.

And in this last chart where you can find the actual measurements of our anchors.

As you can see we are trying to show everything needed to the smallest detail, make a use for it.

It is important to check all the parameters in your boat that are related to dimensions and weight. Please make sure that your boat can accommodate the anchor you choose.
