"An impressive, and typically Joyon aspect of this tale is that to make the record attempt it was important to remove IDEC’s propeller to reduce drag. To do this, on the way out Joyon had moored IDEC up to a buoy while he personally dived on the propeller, taking more than a dozen attempts before he was able to remove it. After the collision with the buoy, rather than calling in assistance Joyon sailed back to the buoy on the Hudson River he’d been tied up to two hours earlier...and get this...with the wind and sea up thanks to the onset of the depression, once he’d turned IDEC head to wind close to the buoy, Joyon dived into the water with the mooring line for his 100ft trimaran and managed to tie IDEC up this way... He then dived once again on the prop shaft to reattach the propeller before returning to Brooklyn Marina. Incredible."
