As for the technical aspects of the shot, there are a few things i might suggest...
As the scene looks quite bright, IE, no cloud, good sunlight etc, you can afford to use a lower ISO. Infact I think this has already been mentioned. In turn however this will mean a longer exposure. Perhaps ISO 200 at f9? and then what ever exposure to suite, which I would imagine to be somewhere in the region of 1/60th - 1/200th, which is easily fast enough to be used hand held. The smaller aperture would give a longer depth of field, which although not noticeably necessary in this shot, in general would help.
A circular polariser would have been magic in this shot, as it would have brought out the sky and increased the overall saturation of the shot a fair amount.
As for the composition, I cant help but feel that an everso slightly higher viewpoint would have looked awsome. This would have seperated the top of the boat from the horizon, and also allowed you to loose the wood at the bottom of the shot, whilst still keeping the horizon on the top third line.
Of course these are really only small points, and a matter of personal opinion. But I do like this shot, and the location looks awsome. Very tranquil indeed.
