You say:
I started off photographing boats as a hobby about a year ago and since then I have expanded my repertoire into other, more aesthetically satisfying, forms of photography. I am a Newbury based Photographer.
If I were you, I wouldn't say that I started boat photography as a hobby a year ago. That tells me you're relatively inexperienced at the job. In fact I wouldn't reference the hobby element at all. What does it add to your story?
Also, you are implying that although you will photograph boats, you'd rather be doing something more aesthetically satisfying, which won't go down very well with boating enthusiasts whom you seem to be targeting... if you're after catching a sailor, be passionate about sailing.
