Scillies ferry tickets

Hi, I am excited to be rowing at the Scillies this year but due to exam dates at University i need to find someone that would like an extra day on the island as i need to come back on the monday but have tickets for the tuesday (7th). If ayone is interested in swapping crossings i can offer one or two tickets for tuesday in exchange for either crossing on the Monday (6th). Obviously i will pay any charges incured, please let me know asap either on here or on the Swanage sea rowing club website or facebook page. Thanks, Georgia
