Docking Boats Together
Multiple Boats

We permit the rental of multiple boats. Sam’s Dock prohibits docking of any watercraft with any of our boats, Waverunners, ski boats, party boats. This includes boats rented by us, or your own personal boats. No docking together of any kind is permitted. This is a safety concern to swimmers and guests. Any damage costs incurred by docking boats together will be immediately charged to your credit or debit card.


We have only one boat offering electricity. The Tejas Event Boat has electrical outlets, and full electric kitchen and sound system.

Many of our other boats and watercraft off ports where you can plug in an AUX cord from your phone to play music over the sound systems. We sell AUX cords in our Ship Stores.  They periodically sell out, so to be sure you can play music during your rental, please bring your own AUX cord(s).

For our Party Boats other than the Tejas, we rent generators offering two(2) outlets for use by caterers and DJs.  We have two generators…they can be rented together, connected, providing 4 outlets.  These generators are Honda gas-powered, are quiet, and last easily for 3-4 hours.  Be sure to rent generators at the time of booking as they do sell out.


Feel free to hire entertainment such as a DJ or musicians for your party boat charter.

All caterers and entertainers are included in the maximum capacity count for the party boat reserved.

NOTE: The only party boat with electricity is the Tejas.

All other party boats have a port where you can use an AUX cord into our speaker system(Deluxe and Yellow Roses).

If you have hired a caterer or a DJ, many supply their own generators, and we rent them if desired(giving access to two-2- outlets per generator).

Exchanging Passengers

For guest safety (…and to avoid damage charges to your credit card), after leaving the dock, it is prohibited to return to the dock to exchange passengers.



Exchanging – Exchange – Swap – Passengers – Boats


Homemade, purchased, or catered food is permitted on all watercraft and party boats. Sam’s Dock does not provide food, beverages or ice. Our captain and crew are not permitted to cook or serve food or beverages.

Grilling (of all types, charcoal, propane, or electric) is not permitted.

Our Tejas comes equipped with a full kitchen, with full-size appliances…all of which may be used by our charter guests.  For complete details please contact our Charters/Event Manager Teena Duff by calling (469) 404-6247.  Ask Teena for a tour!

Sternos are permitted to help keep food warm.

We provide one(1) 6-ft rectangular table for you to place food, snacks and beverages.  We have a limited amount of chairs on all party boats.  If you require additional tables, chairs or coolers, please feel free to bring your own.  Contact our Charter/Events Manager, Teena Duff for more details pertaining to each party boat by calling (214) 717-2335.

We rent a very-limited supply(2) of generators to use to keep food hot (crock pots etc) as there are no electrical outlets on our rental boats or party boats.  Generators provide 2-outlets, are gas-powered, quiet, and last for approximately 4 hours.  Please be sure to reserve a generator when you make your reservation!

Feel free to hire a caterer if desired…many customers do!  Note that caterers and staff will count towards the maximum capacity of your boat…keep that in mind for your guest count!  Sam’s Dock is not responsible for your loss of monies paid to vendors (ie DJ, Catering) when your charter/rental must be cancelled/postponed due to inclement weather. Please keep in mind that most vendors will charge penalties if events are cancelled within a specific number of days/hours prior to the event.  We do not issue rain checks in advance.  If you contract a vendor, and your rental/charter must be cancelled due to weather, you are fully-responsible for the penalties.  Sam’s Dock will not entertain any requests for early rain checks, or to cover penalties due to cancellations on short notice, including the day of the event.

We supply one(1) large cooler on every party boat.  It comes empty, so be sure to purchase ice (enough for the duration of your rental) and all beverages!


Fuel is NOT included in our rental costs.

Fuel is charged at our Ship Store on the day of your rental.

Should your credit/debit card decline for the cost of fuel, the amount paid for the rental is non-refundable, cannot be applied to a future booking and will be forfeited.


Fuel IS included in party boat rentals.


No grilling of any type is permitted on any of our watercraft.

Charcoal, electric, and all other types of grills are prohibited.

We rent propane gas grills on our Deluxe and Yellow Rose party boats ONLY.  Please request one when you make your reservation.


Hookahs are permitted (on party boats only).

Capacity Of Our Boats

Everyone who boards the boat, whether a caterer, DJ, or guest must be counted as a passenger.

This is STRICTLY enforced as it’s mandated by the Texas Parks & Wildlife Department and US Coast Guard stability allowances. It’s not a Sam’s Dock rule, so please do not ask us to bend it as it puts everyone at risk.

Capacities of all boats are listed on our website.

LESSEE agrees that the watercraft rented will not exceed the maximum-permitted occupancy and weight limitations.

Pets – Dog Policy


Dogs are permitted on all rental boats excluding Waverunners and Craig Cats.

Our captains and crew are trained to keep passengers safe only while on board our boats. They are not trained lifeguards and should not be regarded or looked upon as such.  You swim at your own risk at all times.

Guests must obey all commands and direction of our captains and crew at all times…such as bad weather, unruly conduct etc.

You may hire and bring your own lifeguards if desired.  They will count towards your boat’s maximum capacity of passengers.  Many school groups hire and bring their own lifeguards.

Swimming is permitted on all watercraft, boat rentals and Party Boats(except Tejas and Miss Gloria).

We rent tubes(tow rope included), skis, wakeboards, kneeboards and surfboards.  Feel free to bring your own water toys!  A free air pump is available at our Ship Stores for inflation of tubes etc.  Tubes are rented for towing only with pontoons, tritoons and ski boats.

NO SWIMMING is permitted on the Tejas Luxury Event Boat or Miss Gloria.


On boats where swimming is permitted, swimmers must exit the water at dusk(or earlier by command of the boat captain).

Wheelchair Accessibility

Wheelchair-bound customers are welcome on our boats!

We suggest a pre-cruise visit to our marina to see the layout of our docks, parking areas, stairs etc. Our dock hands or location manager are happy to give you a tour of the facility including width of the gates when boarding boats, access to restrooms etc.

Please keep in mind that water levels and conditions could make it impossible for your wheelchair guest to board the boat. Be sure to bring enough people to assist in lifting and loading the guest onto/off of the chair/boat.

You are responsible for your guest’s safety.

We’ll do the best we can to make your trip easy and enjoyable!
