We've lost a good friend. Adventurous, amiable, energetic, always keenly interested in his friends. My wife and I miss him and his laugh already.

Bill Mathers was co-founder of Ipco in Singapore which successfully delivered turnkey marine infrastructure in difficult locations worldwide in months rather than years. Due to the time pressure and remote locations there were always unforeseen and project threatening problems. Bill was the man who sorted them out with no regard for his own safety. I owe him a huge debt for the success of IPCO. Bill, Per and I enjoyed a sailing reunion a year ago in the BVI and he was the same old Bill. Hard...

I first met Bill over 30 years ago when I began working for him at Pacific Sea Resources in Annapolis, MD. What started as a job turned into a lifelong friendship. Over the years, Bill became a friend to my 3 children as well. I will always remember Bill´s hearty laugh and his gift for bringing people together as well as his passion for any idea, project or a person he held dear. I was lucky to be one of those people. Fair winds and following seas, Bill.

.... when reading Bill's message in 'Treasure of the Concepcion' i thought I'd try to get in touch one more time ... sadly 2 weeks too late. Farewell Bill, a full life well lived.

I met Bill in Singapore in about 1977 through my then husband, Peter Barnard. Bill became a good friend, we sailed with him on So Fong and played tennis at our house in Ridley Park. He encouraged me to learn to scuba dive. This became a passion during my remaining years in Singapore. He visited us in London and then disappeared. Yesterday I read his message in 'Treasure of the Concepcion' and thought I would try again to find him.

I am saddened to hear that the ever strong and enthusiastic Bill has passed away. I send my condolences to his family and many friends. I knew Bill from East Woods Grammar School, and although we were seldom in touch, every so often he would call and we would enjoy catching up. His life was amazing. His accomplishments were wide and varied, and with his sharp brain, witty sense of humor, and deep caring for others and his projects, he outdid us all. His kindness ran deep, and for all those...
