Hi again, Maria and you're most welcome!
I'm happy to clarify. If your friend requested something like a 'cabin tide clock', I don't think this is too big for a cabin on a smaller yacht. What you're seeing in the pictures on the sites I included in my previous answer are enlargements, so you could see the details. It states on the site with the description of the cabin tide clock, that the dimensions are:
Outside diameter 5½", face diameter 3", depth 1¾", so less than 6 inches in diameter is not a big piece at all.
As I mentioned, the differences between the differently named clocks for yachts are based on their appearance, size, and function. This cabin tide clock is not just a clock, as it has an extra hand which demonstrates the influence of the moon on the tides. If you would like to purchase a more 'plain' clock that is suitable for a cabin (bedroom), you can choose one that does not have this extra hand and functions solely as a clock. If you want to be sure it is not a huge piece and will fit nicely into the cabin on your friend's smaller yacht, simply look at the dimensions given on the sites that sell this type of clock. If you're looking to only buy online, this is the only way to know the dimensions of each individual piece, and you can call the company that sells them, to verify it's the correct size for your purposes.
If there's any way you could go shopping in person, and visit any clock shop and/or nautical shop to look at the different clocks, that would be better; however, if you would prefer to order online, the pictures are quite detailed and the sites provide other details and dimensions.
In my humble opinion, I love the look and functionality of the cabin tide clock, and would prefer that one if I had a yacht. If you need to consider price as well, choose one of the others that is just as beautiful, but a little less costly.
Please let me know if you need anything else.
