IMOCA Open 60

Dee’s IMOCA Open 60 yacht has been designed specifically for single handed round the world racing. The yacht is currently in refit in Spain ahead of the Barcelona World Race later this year. Refit involves taking the boat apart, servicing and/or replacing the main components and then putting the whole thing back together again.

Aviva Open 60

The Refit Process

It is truly amazing how quickly the boat comes apart, however, the time and effort comes with servicing and putting everything back together. The pressure for the shore team comes at the time of re assembling the boat as they need to be certain that this process is carried out correctly and in a way that will withstand the harsh environment of a round the world race. It is at this time we hope to avoid problems that may arise and therefore need solving during the race - costing Dee time and effort. Once the boat is back in one piece and launched again, we then have an inspection from the IMOCA measurer to ensure we conform to the rules set out by the class.

It is an ongoing process to prepare a boat for a round the world race and it is important all eventualities are thought of and complete trust is put into the shore team carrying out the process. After all -they are preparing the boat that will be looking after Dee’s life!
