Do you mean as in 'ship's telegraph', which communicates the captain's commands for speed and direction to the engine room? If so then it certainly is still in use, at least on older ships. I'm sure that recently-built ships rely primarily on electronic power controls to conn the ship, but they may still use telegraphs as back-up in case of electrical failure.
If you mean 'wireless telegraph' (CW radio telegraphy), that's been superceded by voice radio and satellite communications.

Ship-to-shore and satellite radios have pretty much replaced telegraphs. You'd be hard-pressed to find anyone who could use a telegraph key these days.

I believe for the most part no. I remember an article in the paper a few years ago the said the US Coast Guard was going to stop monitoring for Morse code. Nowadays I believe most ships use satellites to communicate around the world.

No, telegraph is not used on ships now. Ships now carry mostly VHF radios (20miles)and satilites links. They also have MF/HF radio sets for medium range commucations out to about 200 miles.

Ships use everything from radios to satelites, to internet connections. They still also using flashing light and semaphore in a lot of navies.
