The Harbour Station service begins tomorrow morning at 10:30am.
Randall Hope of the Merchant Navy says you share a bond with your shipmates that never leaves you.
He says sometimes you have a convoy and it gets torpedoed and the guys are on lifeboats and you have to run over your own men.
Hope joined the Merchant Navy in 1944 when he was working at sugar refinery.
