Starlink is a constellation of thouands of satellites developed by SpaceX to provide affordable internet coverage around the globe. The satellites are launched about 60 at a time on SpaceX reuseable rockets. 

The majority of the satellites are in inclined orbits of 45 to 53 degrees north and sounth of the equator which covers most of the inhabited areas of the world. Additional satellites cover the polar regions. SpaceX continues to launch additional satellites on a regular basis and there will be many thousands more.

The fixed domestic subscription is targeted for home owners that live in underserved areas where cable and other internet services are not available. 

The standard antenna and router hardware has a one time cost of $599 and a subscription of 110/month. Residential users should expect  between 50 to 200mbps download speed and 10-20mbps upload. 

There is also a High Performance hardware option for $2500. 

With the residential plan there is a Portability option for and additional $25 per month that allows one to relocate your terminal anywhere within your home continent. This might be suitable for snowbirds that migrate for the winter and summer seasons. 

The residential plan remains in service continuously.  For RV travelers that are mostly on the move, the RV plan is the better choice. Unlike the residential plan, the RV plan can be suspended when not in use. The residential plan will have higher priority throughput during congested times and in populated areas. 

There is a backlog on residential accounts as systems are at capacity, whereas the RV Plan is immediately available. I believe that after subscribing to one plan or the other, one cannot switch between plans, even though the hardware is the same. 
Starlink Maritime is intended for commercial shipping, cruise ships, and large megayachts that can afford the $10000 hardware cost that includes 2 high performance antennas and the monthly charge of $5000 per month for downlink bandwidths of 100-350mbps and uploads of 20-40mpbps. 

Starlink Maritime can be paused and resumed on a month by month basis. 

Starlink Maritime Coverage Map
Very many cruising yachts subscibe to the RV plan and are over the moon with the results. This is not intended for use while in motion, but as of October 2022 many cruisers have found that the system works fine at regular sailing speeds below 10 knots. They are also finding that Starlink service is available sometimes hundreds of miles offshore. 

No one is sure whether the use of Starlink RV service will be restricted or "geofenced" to prevent offshore use on small boats in the future, but there is speculation. 

Of course, the average cruising sailboat would not be able to afford the full blown Maritime service at $5000 per month, nor do they need the vast bandwidth supplied with the Maritime service. Most cruising boats need access to email and messaging with occasional uploads and downloads of weather reports and charts and photos and short videos. 

The RV service with a monthly charge of $135 is well within most cruising boat budgets especially since this can be paused during the off season and only activated on months that the boat is in service. 

It is also not known if the RV service will work deep offshore once the laser intersatellite links are in service. 

There is an informative private group on Facebook of Starlink On Boats where actual users exhange experiences and solutions and advice on mounting harware using the Starlink RV service.

There is a second Facebook group called Starlink for Yachts and Maritime Users.

One needs to apply to join either group. 

Starlink Coverage Map
When subscribed to the Starlink RV plan the service can be used at any destination in  the coverage map. The hardware cost is $599 with a monthly service charge of $135/month. Starink RV users can expect 50-200mbps download and 10-20mbps upload when in uncongested areas. They can expect their bandwidth to be deprioritized over residential users in heavily congested areas at peak times to 5-100mbps download and 1-10mbps upload.

Starlink for RVs service can be paused and unpaused at any time and is billed in one month increments, so it can be turned off when not in camping or cruising season. 

I believe that the Residential plan with portability does not allow this pause-resume feature but it does have the prioritized service. I do not believe it is possible to switch between residential and RV plans although the hardware is the same for both. . 
Starlink Business uses the high performance antenna with a one time hardware cost of $2500 and a $500/month service charge. Business users can expect 100-350 mbps download and 10-40mbps upload.

A domestic Starlink terminal is extremely easy for the consumer to install. Elon Musk describes the antenna as a UFO on a stick . 
The first generation antennas were circular measuring 23.2" and weighing 16 lbs. The second generation are rectangular measuring 19" x 12" and weighing only 9.2lbs.Both come with a ground pedestal but several other mounting options are available. 

Out of the box, one simply places the antenna in its tripod with a clear view of the sky. There is a 75 foot cable with proprietory connections on each end to connect to the Dishy and to the wifi router. The router is connected to houshold supply voltage. 

One downloads an app from the Android or Apple app store to monitor the dish for optimum placement. The antenna automatically rotates in azimuth and adjusts tilt for optimum flat panel viewing of the most satellites. 

Unlike geostationary satellites (that are always toward the south in the northern hemisphere), the majority of available Starlink satellites will be found toward the north, so the dish should tilt slightly toward the north. The opposite is true in the southern hemisphere. 

It is possible to disable the motors and mount the Dishy flat on a solid mount. It is generally best to have a small tilt to the mount so that water (and snow) can drain off the surface of the antenna. 
The Starlink hardware and subscription can be purchased and ordered online, directly from Starlink.

This great, unofficial website shows the actual position of each Starlink satellite and the connecting ground earth station hub. This site is not affiliated with Starlink or SpaceX. 

Because of the complexity of the webpage it uses extreme resources and is best viewed on a PC. It is not suitable for viewing on a mobile device. 

If you click on an individual satellite it shows the ground coverage. I believe the blanked out section shows where the satellites automatically blank out the areas in the direction of the geostationary satellites to avoid interferrence. As the satellite moves north or south, the blanked out area moves as well. 
This is another excellent site showing position and details for each Starlink satellite including launch and orbit data and altitude.
