North Cliff Boating Club in Hornsea

I am disgusted with this boat club. My husband has been a member for a number of years but has recently died and I wanted to let them know that and the date of the funeral service especially as he has a boat there, but there is absolutely no way of getting in touch with them. The phone number on the website says "this number is not recognised", the website just says if you want to get in touch visit any weekend - a bit difficult if you do not live in Hornsea, cannot drive for medical reasons and and are severely disabled; and when I tried to poast a letter it was returned by Royal Mail with a note saying address inaccessible. They are obviously some kind of highly secret organisation. I am most upset. I could do without this stress at tthis time.
