“James knew his game! Having observed many similar boats remain unsold elsewhere I was a little dubious about ours being sold, i fully relied upon James who informed me throughout the process, estimated the value and she sold very soon after. He held firm on our agreed price, following the sale, Lynne took over and everything was a smooth transition. Top quality! Without doubt i would recommend Waterside. ”
