Can I buy Direct TV just for a month?

Thank you for the response 

Does this same comittment apply if the direct tv is used for a yatch?

Does this same comittment apply if the direct tv is used for a yatch?

yes if even available

@Juniper  any thoughts?

Here is the case: 
I have a client who has a small leisure yacht and wants to be able to watch TV on it.

We are located in Central America and the yatch isn't used that much, so a residential account won't work for him.

Is there a maritime account that he can apply for to use DirecTV for 1 month?

not that i know of almost all providers require a 2 year commitment.

Is there a maritime section that Direct TV offers for leisure yatchs or boats to have TV?

What type of acccount do I need for my client if I want to install DirectTV on his leisure yatch?

DTV doesn't provide a month only service they require a 2 year commitment only streaming services are month to month.

There are dishes that can be installed on boats to receive DTV signals.

Ok, but what type of account do I use to receive DirectTV signals on a boat?

And also is streaming the same as TV? What is the difference between them, If i choose streaming will I get the same channels that I get for buying TV services or do I need something else for it?

I assume you need a RV(mobile) account with the 2 year contract.

Streaming uses the internet to send content to you so the yacht needs to have satellite internet service, AT&T Now has most if not all DTV channels but then most streaming providers do too.
