Thank you Jenny, I was due for renewal, they are working on updating the class in thier internal systems to add a drop down box to ask if you are a member of the D15 Association, so it's not automatically added to the renewal currently. When I phoned I did have to reference the link to thier website...

Hi Jenny, I have just spoken to the renewal team at Noble Marine, they are not aware of a 10% discount, is there something or someone we should be quoting?

I am now the proud owner of 861, sailing out of Draycote, fingers crossed I will get out on a few of the circuit races this year.
