I no longer speak in any official capacity for the Yacht Club, but I beleive that in 2013 racing boats will be expected to complete penalty turns should they hit moored boats in the harbour. Whilst this might not seem very draconian to the non-racer, it will have the effect of a) identifying boats where the helmsman has acknowledged that a collision has taken place b) there will be peer pressure applied to those who hit a moored boat and don´t perform turns, since this will be a breach of the racing rules, which then becomes a disqualifiable offence c) causing racing boats to give moored boats a wider berth, since the penalty talken in a foul tide will have a negative result on finishing position.
In pounds, shillings and pence, there is no reason for a boat that collides with a moored boat not to admit to the offence, we all carry insurance, which is a pre-requisite of launching in the harbour and competing in SYC races.
I have sat in on several discussions in the past following accusations of "hit and run" offences relating to moored boats. Some reported incidents have been in areas of the harbour where racing boats simply would not consider going, since there is a clear racing line through the harbour and the bag, which is seldom deviated from. However SYC has never been backward in insisting that incident reports are completed and handed into the harbour office when there is clear evidence of wrongdoing.
Finally, not all sailing dinghies in the harbour originate from SYC, or are racing in SYC events, there are at least two teaching establishments and several hire establishments, as well as visitors, hired powercraft and powercraft operated at night with inadequate lighting, all of which are capable of inflicting damage to moored boats in the harbour.
One thing that the Harbour Board could consider is simplifying the incident reporting procedure, a simple online form, with who, what and where, together with contact details, would enable a more detailed report to be obtained at a later date should damage be discovered.
Since I would suggest that many "hit and run" sailors may not be aware of causing any damage, and therefore don´t report incidents.
