I resisted replying yesterday, to avoid being one of many jumping to the defense of the Shear Water. Too many boisterous responses are sure to put off any posters wanting to express a counter view, which is not too constructive for a debate.
That said, like many here I am a big Shear Water fan, but I do understand that coming onto the Wetpixel forums and saying you didn't enjoy a trip - can elicit a response from the community akin to if you posted saying "that underwater photography is a waste of time".
The Shear Water offers a truly unique experience in diving and I cannot think of any other trip where you have so much great subject matter sitting on your dome, day after day. I love it and I am going again in a couple of weeks. But I think that the original poster raises an important point - that the Shear Water trips aren't for everyone, indeed aren't for the majority of divers. And it is important that these views are expressed - so that people can understand if Shear Water trips are for them.
