Determining the correct size for your boat requires a simple calculation using the table below. Unlike most manufacturers Rocna factors in the weight of the boat in its calculation as well as the length. The table below applies to a standard monohull, if you have a catamaran or monohull with a large wheelhoue or flybridge then it is recommended that you select an anchor one size larger than stated. If you are unsure or would prefer us to look up the correct anchor for you, please fill in the form at the bottom of this page with as much information as possible and we will make a recommendation based on this. Alternattively please contact us on 01202 922189 or info@marinefactors.co.uk

We are happy to advise you of the best size anchor for your boat. Please fill in as much information as possible in the form below and we will advise the correct size of Rocna or Vulcan anchor for your vessel (and whether we feel one will fit better than the other). If you don't know length or weight please just give us the make/model and we may be able to look this information up in our database. Once this form is filled in we will endeavour to respond to it within 24 hours.
