THE wine was cooling, the sun was warming, the caterers were busy organising the buffet and the crew were in cruise mode as the luxury motor yacht glided around Hongkong's outlying islands. There was nothing left for we hi-tech executives on board to do but discard ties and jackets and relax. The host, Jeremy Comport, of specialist boat firm Seanergy and Darren Shaw, said the luxury voyage would replace the junk trip as the executive option for a day ''bobbing around in the office''. ''Companies are increasingly upgrading to 'white boats' because of their versatility,'' he said. A tour of the boat revealed how cleverly every inch of space had been utilised. The main saloon featured a sofa area with tables and chairs, and an area that could be set up as a dining room or boardroom. The compact galley was remarkably well equipped and, above deck, the steering station commanded a clear view across the sloping bows, where some serious sun-lounging would be bliss. The padded cockpit adjoined a secondary sun deck, which served as a canopy for the principal sun deck located at saloon level.
