I’ve been a sailor all my life and have stayed with Harken for 40+ years. I decided to try out a Blueshark 38mm block on my day sailer to see how they were built. So far I’m amazed at the quality of the product.I’ll continue to use Blueshark on all my products from now on.

While I wouldn't use in a high stress or demanding location, these are working great on our davit system to lift our dinghy and should last a long time. Perfect for the price!

Used this to replace a worn out fiddler block on my sailboat's boomvang. Works perfectly, ball bearings are good and give a nice pulley sound when spun.

I am sure they are fine for their purpose but not for mine. Quality looks fine but they are too small for my application and I need to return them

I hoped this would be a good size to handle my sailboat's main sheet, and it looks correct. It took a while to arrive, but really impressed me with how solid it feels and how well machined it it. This is an excellent bit of work for the price.
