Re: Calculating the sailing time of cross ocean course

Lots of online information about circumnavigating Antarctica. In fact, it’s being done right now, see: https://www.vendeeglobe.org/en

A budget of about $6m for the boat, little bit of practice and should be able to knock it out in as little as 74 days including the run back to the house.

Re: Calculating the sailing time of cross ocean course

If this is not a troll then a couple of answers occur to me. They might sound flip or somewhat rude but not intended to be so but instead to emphasize the seriousness of what the OP says he intends.

1. If you have to ask then you aren't ready and shouldn't even think about it.

2. This is like someone who has zero climbing experience planning a climb up Mount Everest.

3. For the budget you propose you better concentrate on a boat that will keep you alive, not one that will go fast.

Re: Calculating the sailing time of cross ocean course

If you are interested in a general idea of the capability of a given boat, I think Evans Starzinger gave a formula:

Daily Ave. Mileage = 24*(2.62 + 0.066*SA/D + 0.051*LWL)

I have found it pretty good for our boat as a general average. Of course, it depends on whether your course is mostly downwind or mostly upwind. In the Southern Ocean, it it probably useless.

Yep, that Evans' & Beth's formula.

I wouldn't worry too much about the time to complete. Given what you told us about yourself, I'd think Poseidon will make sure that you will have all eternity to finish the trip :-)!

If you are in a hurry strap on a 747 and forget about sailing.

My question is: How to calculate the sailing time? While I see data on a ship's maximum sailing speed, I am aware that the speed depends on winds and currents.
tldr; Given the distances, boat type and season, how do I reach the most accurate estimation of the time it will take to travel? And what is the fastest boat that is capable of making cross-ocean travels on a budget of 100k-200k$?
Thanks in advance!
If you have no sailing experience and are asking these questions I have to assume you are just fantasizing. You can Google/Wikipedia/Guinness World Records to get the history of Antarctic circumnavigations to get some idea who has done it and some idea of the details involved. But note that there is a saying; "Below 40S there is no law, below 50S there is no God." A circumnavigation of Antarctica would require a voyage below 60S.

You must answer the question yourself. Here are the necessary steps:


0. Decide to devote your life to this project. Be intelligent, teachable, friendly, in excellent health and decide a family life is not your highest priority.

1. Learn how to sail small boats and volunteer as crew on local racing boats
3. Be good enough to be recommended for premium racing events
4. Work your way to the highest level of crew positions on long distance racing.
5. Know the right people to approach for a crew position in non-stop round the world racing. Do the race on someone else's boat first.

6. Through all this, save enough money to buy and maintain a boat of your own capable of making the circumnavigation (not circumvention) of Antarctica.


Only a minuscule percentage of all seasoned sailors worldwide, have what it takes to do a voyage such as you proposed. Keep your dreams alive, but start at the bottom with realism.

Re: Calculating the sailing time of cross ocean course

With 0 sailing experience, calculating that you probably needn't worry about it.

I perceive that the answer largely depends on which season you wish to schedule your circumnavigation or Antarctica.

Would that be winter or summer?

West Marine gives you a discount for volume. Buy seven days get three days free.

Re: Calculating the sailing time of cross ocean course

with this highly trolling question the answer is as trolling; it depends on at least the following...
1. Sailing and Seamanship Experience
2. Boat
3. Wind
4. Currents

Get 1+2 and check again in x years

PS. I think the OP must have meant circumnavigating which is also a bad idea but completely different than circumventing (which means to bypass or avoid)
