Reviews for Tantallon Marina
Incredibly nice people, 2016-08-03
Captain: , Green Cove Springs, FL (10)

My wife and I stayed here for the month of July 2016. Rhonda, the marina owner is one of the nicest people we%u2019ve met. She loaned us her personal car to pick our daughter up from the airport and offered it to us any time she saw us walking away from the marina. She also called or sent us a text whenever we received a piece of mail. Rhonda arranged multiple get-togethers for the marina during our four weeks here. She really is just a super gal.

The marina is small and privately owned and there are some challenges that keep it from getting a higher rating. Our first challenge was getting down the creek to the marina. We came in about an hour from high tide and we saw some 4%u20196%u201D depths, so when were ready to leave we literally had to get up before dawn or we would have been stuck there until late afternoon. While we were there the marina had one operating washer and one dryer. They also have one shower. The washer/dryer and shower room entrance are all in the boater%u2019s lounge. Many of the marina residents are smokers and so the boater%u2019s lounge frequently had a very strong cigarette smell. This was by far the biggest negative for me and my wife but we are both non-smokers. We are also not pet owners and there were several dogs on the property so that is a bit of a negative for us as well.

The marina is a tad remote. There is a Safeway about 2 miles away and there are a few quick eats type restaurants in the shopping center with Safeway. National Harbor, for retail shopping and higher end places to eat, is about 5 or 6 miles away (Uber rides ran us about $15 each way) and Alexandria is across the Potomac (about a $20 Uber ride). To get to DC from this marina it took a 25 minute UBER ride and then a 25 minute subway ride. You can catch the bus about a mile or two from the marina and ride into DC if you prefer buses.

All in all, Rhonda%u2019s personality, her focus on service, and the friendly marina liveaboard residents we met there, tip the scale for us and we would definitely go back to Tantallon Marina when we are back in the DC area again.

Great price and very friendly, 2015-08-04

I left my boat here for a month. Rhonda was more than helpful, doing more then I ask. they dont have a loaner car but she gave me her personal car to use for shopping, getting propane and going to the airport. She also drove me to the Metro. The do not have WIFI but it is planned to be installed soon. There is one restoom and shower in the main office. This is one of the few marinas in the area that allow liveaboards. I will stay here again.

Quiet Live Aboard Atmosphere - very secure, 2014-05-13
Captain: , Tampa FL (30)

We chose Tantallon as our live aboard marina in the DC Area. Rhonda (Owner) will bend over backwards to accomodate you. Tantallon is simple living (privately owned) but with all necessary ammenities and you can't beat the price in this area for extended stay. The approach is shallow but we came in on high tide (drawing 5 ft) with no problems. The marina will send a small boat out to meet you at the entrance and guide you through the channel if you call (phone) and ask.

Welcomes liveaboards, protected cove, car needed., 2013-07-08
Captain: , Gulf Breeze, Fl (6909)

new phone number is 301-651-7016
dockage is $1.50 per foot power included Extremely protected cove and secure gated access that supports a number of live aboards on various types of boats in varied conditions nested in the upscale community of Tantallon. If you have a car this is the least expensive base for doing DC and area attractions. The entrance is very shallow. I came in 07-07-13 at +.4' above dead low tide and pushed through soft muck twice. I draw 3' so consider the entrance to have a controlling depth of 2.6' at MLLW at those spots. The channel is not marked well so I could have not been in the deepest part when hitting the silt. When you can just see the the Marina favor the north shore for deeper water. Once to the marina and docks there is 6-9' @ MLLW. So only enter and leave at high tide.

Bargain, close to DC, 2012-06-20
Captain: , Dunedin, FL (6425)

Nothing fancy here but floating docks fairly new and in very good condition. Very nice lounge/showers/laundry in center of marina. Locked gates to the docks. Good stop if you want to save a few dollars on the way to DC or Alexandria, both just a few miles away. We stopped as we were ahead of schedule for getting to reserved slip in DC.

A live aboard Marina that is in close to DC. Prices are good. Folks who run it are friendly and accomodating. Other Marinas in the area are much more expensive and hard to get a slip at so if you are looking for a place to live aboorad close to DC this is a good choice. Channel is narrow but can get back on high tide with a 6ft draft. Need tramsportation because it is a good ways through a neighrbhood to get to stores and support services. Also a twenty minute drive to downtown DC. Not the most up to date but Ok and nice folks who run it and friendly atmosphere make up for it.
