It is common for people to lose control of the mast and damage their boat and, in some cases, nearby boats. The marina I use has a policy that all mast stepping and unstepping must take place at the fuel dock after a series of problems with people damaging neighboring boats.


There are some boats that have a counterweighted mast that is hinged at the deck and also affixed to the keel. Common in the Norfolk Broads, I don't think they're used anywhere else. That sort of setup would be perfect for river sailing.

I think that the central problem of cruising the Great Loop is that the various segments of it place conflicting demands on the boat. On the river portions, the mast and the keel just get in the way. What you really want is a nice Gibson houseboat, which will draw less than 3', cost less, have more room, and give you the choice of the the flybridge or the inside controls. And at 16' they fit under the bridges. They will also give you the choice of going faster when you're willing to use the fuel.

You can take those anywhere on the rivers, because of the shallow draft and the relatively low vertical clearance. You can take them on extended side trips where the extra speed helps you get upriver in the current. You can carry a little skiff or 'yak or canoe for a dinghy if you want to run up smaller streams.


Another fact to consider, for river cruising, is that sailboats lose a good deal of their roll stability with the sails down and more of it with the mast down. In congested areas where high speed operation is permitted, you'll get wake from overtaking boats that will really throw the boat around.


The problem is that houseboats aren't suitable for the Great Lakes, or for the coast, because they aren't stable or seaworthy enough. Besides, those are places where most people would want to be able to sail.


On the other hand, with a typical 38'-40' cruising yacht, you'll need 48' to 55' bridge clearance even if you take off your VHF antenna and windex, depending on the boat. In practice what most of the loopers with these boats do is unstep the mast at Chicago and leave it down until they get to Mobile, because there aren't enough sailing opportunities between Chicago and Mobile to be with the stress and aggravation of dealing with a dozen bridges that you're going to miss by a matter of inches, or not, depending on the water level that day. Then they unstep again for the Erie Canal.


I'm told that it's no big deal to step and unstep and that the rates are reasonable. The received wisdom is that there's nothing about sailing on the Tenn-Tom, that is so compelling that you would want to choose a boat with a 51' mast instead of a boat with a 53' mast, just because you could put the mast up in, say, Cairo, rather than Mobile.


Which leads us to the question of how badly you want the Great Loop to be a circular journey on a single boat. I am starting to think of the "Great Loop" as a series of explorations. Explore the rivers in a riverboat, explore the Great Lakes and the coasts in a sailboat.



You can rent boats for specific portions of the journey:
https://midlakesnav.com/canalboat-boats#lock42 - Erie canal


https://www.bigrideaulakeboatrentals...severence.html - Rideau waterway


It's OK to make U-turns. You can motorsail up the Hudson with plenty of clearance, 150 miles past New York Harbor to Troy, then turn around and go back and see the river from a different angle. Or leave the boat in a slip for a week or two and see the Erie Canal in a rented boat.


You can use the high-clearance routes, not only the Welland but also the Lower Mississippi. You can have your boat trucked. So for example, your loop starting on the East Coast could be the St. Lawrence Seaway to the Great Lakes, haul out at Green Bay, truck to Stillwater, then you've got 60' of clearance all the way to New Orleans.



As you've mentioned, the looper resources tend to be powerboat-oriented. The Capt. John website is particularly focused on taking the trip at low speed in a "powerboat with a mast" where the sail is little used, which is far from a universally held best practice. More focus on the ICW and less on going offshore. The looper resources are also organized around making it a "loop" and as a result downplay some potential side trips that are seasonally inconvenient.


Hope this helps.

Re: Great Loop Height Restrictions

I’ve seen a lot of sailboats come through in the fall heading south. All of them over 30’ or so have the mast stepped and lashed on to cradles. The ones I’ve talked with planned to step it in Mobile to continue their voyage by sail.

Re: Great Loop Height Restrictions

Thanks, Adelie.

I'm just starting the boat selection. Given the restrictions on the loop, I'm limiting mast height <=45' and draft <=5'. Length of the boat will, I assume, be in the range of 30' to 40'. Much shorter will likely be cramped and any longer will likely be a bit much for us to handle. What's your suggestion?

Great Loop Height Restrictions

The suggestion is the C&C Mega30
http://sailboatdata.com/viewrecord.asp?class_id=732

Pros:
Retracting keel and rudder
Intended to be trailerable so mast is designed to be dropped without a crane.
Standing headroom at back end of cabin.
Moderate price, $10k-ish
Uses an outboard
A. Easy to get at for repairs.
B. Cheap to replace ($3k new, $2k or less used)
C. Lower drag when sailing.
D. Better fuel availability on the inland portions of the loop.
Comparatively light boat - will provide much better fuel economy, even using an outboard. At 5kt I would expect about 10-15mpg, compared to another larger sailboat at 7-12 mpg vs a trawler at 3-6mpg.

Cons:
No double berth.
Comparatively small boat so storage is more limited.


No double berth would be a deal breaker for me, but I’m hand and willing to rearrange so that wouldn’t be an impediment to me.

On the loop fuel and provisions are going to be more available than passageemaking so storage is a bit less critical.

Once done with the loop I would
Be comfortable taking this boat into the Caribbean, across the Atlantic might be a stretch.

Re: Great Loop Height Restrictions

I saw one vlogger have his mast shipped from Chicago to a Marina in Alabama where it will wait until he gets there. Seems like a nice, albeit probably expensive, option.


I am considering doing the loop on our Lagoon 440 and turning north on the Mississippi river to get to Muscatine IA for the summer and fall. Any thoughts on this 245 mile up river run would be welcomed.

Some boats come up every year. I saw a catamaran of similar size from Key West up in Lake Pepin this summer, which is another 250 river miles past Muscatine. You would want to be aware of river conditions and avoid unusually high or low water. Spring high water can bring quite a lot of floating debris, some large enough to be a hazard. Typically the current is 0.5 - 1 knot in the channel, easy to motor against.


You would want to do this in daylight, and plan on anchoring at night, or staying at a marina.

Re: Great Loop Height Restrictions

We did the loop in a 34' Gemini Catamaran...great option:
- Retract the boards and rudders and you can run in 18" of water.
- Narrow enough beam that you can use most of the marinas
- Still need a crane to pull the mast but really anything over mid 25' range, you really are better off.

You need to pull the mast at Chicago and it likely won't go back up until at least Kentucky Lakes. If water levels are high, Mobile. Then you need to do the same on the Hudson before going into the Erie Canal.

You do need some range to get from St. Louis to Kentucky Lakes motoring.

Do make sure you lash the mast down well. Only place we took water over the bows was on the Mississippi when upbound barges threw 10-12' wakes.

Re: Great Loop Height Restrictions

Hello Cruisers
My name is Gary
I'm wanting to purchase a sailing vessel that's located the Chicago Ill.
My plains are to bring her down the The Great Loop to the Gulf Of Mexico.
My concern is that she has a deep draft keel of 6 feet.
I'm hoping for guidance from those with experience on the TGL.
Will the 6' draft be a deal breaker?
Thank You for the help

No, the channel is maintained to a nominal depth of 9 feet by the Corps of Engineers. In practice there are some shallow areas that are as little as 8 feet at normal pool. Very rarely, the water is below normal pool, usually only by a few inches.

Re: Great Loop Height Restrictions

Thank You Jammer I appreciate the info.
I did research the US Corps charts but didn't know how reliable they are.
One more concern I hope you will ease my fears.
Would the 6' draft cause problems getting to safe night anchorage or entering a marina for fuel and /or previsions.
I will research the passage as much as possible.
Thanks
Gary

Re: Great Loop Height Restrictions

Take a look at 3rd party charts that show more detail based on crowdsourced depth data. Navionics is one example. There are others. They will show depth detail where the official charts give you nothing.


Anchoring, the things to watch are wing dams and snags. It is my experience that areas with wing dams will have wing dams where none are charted. Most (well, many) of the wing dams were constructed a century ago and have not been surveyed accurately; also, ice moves the dams. Therefore, in a channel with wing dams, you can't (safely) anchor outside the channel unless the water is high or you conduct your own survey.


There are areas outside the channel where snags, that is, submerged logs or tree stumps, are hazards.


My experience is limited to the ~100 mile stretch between Wabasha and the head of navigation in Minneapolis, but in those reaches, there are plenty of places to anchor. Six feet of draft does make it harder but not impossible. You can sit on the edge of the channel, or find a backwater, or find a disused barge mooring.


Marinas, I would encourage you to do your research and identify specific harbors where there is depth. I have stayed in marinas that I would not enter with a 6' draft. Then again there are many that have far more room. You will not be going as far up as my area, but by way of example, Lake City Marina is a deepwater facility, as is Hansen's Harbor, both on Lake Pepin; these have both gasoline and diesel. Watergate marina's fuel dock is in deep water. There is a free place to dock during the day in Red Wing that is in deep water. I believe the fuel docks there are in deep water also but can't remember the soundings when I was last there. On the other hand, King's Cove is only accessible via a shallow channel that I would not trust with a 6' keel; River Heights Marina would also be iffy depending on water levels.


A dinghy would increase your options especially for groceries and shore excursions.


The pattern in the Upper Mississippi is that immediately upstream of a lock the water is deeper and there are more options for anchoring. Immediately downstream it tends to be more shallow. In between is, well, in between.

6' is not a deal breaker by any stretch but there likely will be marinas and anchorages you can't use.

Fully loaded barges are typically 8-10' draft so the main channels aren't a problem but a lot of the marinas are focused on houseboats and small runabouts....typically around 3' draft...so they don't really need to be maintained for deeper draft.

A complication: River levels can go up and down substantially by season and after storms, so there are a lot of places, you will have no issue with during high water where you may not bee able to get into at low water.
