“It's rare to find a yacht broker that really delivers. I've just sold my boat through Val Wyatt and they far exceeded my expectations. I delivered the boat on a trailer to them one morning and by the time I had returned home that evening the boat had been prepared, launched, photographed, put back in undercover storage and listed on the website. Throughout the sales process they always kept me fully informed and were quite happy to wait until they felt they had the right offer. Highly recommended.”
