Alas no. I couldn't afford the mortgage! When I called Gieves about 20 years ago, they quoted me in the vicinity of $2000 for one. The only thing I ended up buying from Gieves was the chain and lion-head frogs. Even that cost me about $50. I had my cloak made by a dressmaker in Barrie. I went in one day on a whim and asked, "can you make me one of these?" I gave her a picture and a written description. It turned out beautifully and I'm the belle of the ball (in the winter anyway). ;D As a garment, cloaks are pretty simple, so having one made by just about anyone shouldn't be too difficult. The thing to remember is that it needs to be black wool (mine is melton) with a white satin lining. It has a turndown collar and four buttons. There is actually a special size button for boat cloaks, but I've never been able to find any, so I use regular size ones.
For the most part, Gieves and Hawkes have gotten out of the uniform business. They'll still do it, but they're horrifically expensive ("Gieves the Thieves" my Brit friends call them). The big military outfitter in the UK lately is G.D. Golding. I don't know if Golding does them or not. Another good place is Baun and Company Naval Outfitters in Portsmouth; however, when I asked them years ago about a boat cloak, they said they don't sell them.
