Hi, do you have a photo so we can see where the non-sharpness is coming from?

I shoot the 60 mm Canon extensively, have found it to be an extremely good macro lens (much more reliable autofocus than the 100mm, especially in low light).  Can you achieve sharp focus topside?  That way you can determine if it is a lens issue or not.  Here is an example macro shot from a Canon 60d from my last trip to Indo:

SOunds like you may have an issue with your lens, I've found mine to be very sharp under most conditions.

If your topside images are sharp (take a picture of a ruler at an angle) to make sure that not only it is sharp but that it focuses where you want it. If it is sharp then try with the housing and port to make sure that your port is not causing some image degradation (unlikely but it can happen)

Try it on land against something where sharpness is easy to judge - the lens SHOULD be very good.
I use it underwater with the ikelite flat port and extremely pleased with the images - fast focus and exceedingly sharp.  I generally shoot f/8 to f/11 (sometmes higher) and it is to my eye, perfect.
I always use centre single focus point to make sure the object i want is focus locked before recomposing.  With a strobe, shutter speed should not be an issue at all for the image provided the subject is well lit by it.

The ruler suggestion above on land is a good staring point to check the lens is actually performing as it should.

Underwater all i can suggest is that its focussing on the right subject and not auto picking something else in the image.

I have the Canon 60mm macro.
I find it a great lens and i love the shallow DOF you get with this lens.
RE focus I have found to lock focus then move camera in and out to define what I am focusing on this can be hit and miss when diving.
I would try what String has suggested take some land photos using your 60mm and see what results you achieve in case its faulty lens?

cheers
