The Panama Canal provides a shortcut for shipping travelling from the Pacific Ocean to the Atlantic Ocean and vice-versa. Instead of having to route to the south of South America and then back up a distance of about 5000 nm the canal offers a mere 50 mile transit. This comes at a price, calculated by a complicated formula, designed to maximise revenue to the canal operators. The original canal opened in 1914 and was an immediate success. In the first year it handled about 1000 ships and by 2008 it was handling nearly 15,000. These figures alone don’t tell the whole story because ships were getting bigger and bigger and one of the limits to the size of ships was the size of the locks in the Panama Canal. Ships that were built to fit (just) into the locks were described as Panamax ships. That is why so many cruise ships, container ships and car carriers are 32.3m wide and have a draft of under 12.6m.
The expansion of global trade and the increase in shipping meant that the canal was becoming a bottleneck with frequent delays and queues of ships waiting to transit. Fees for queue jumping became ever more expensive and ever more necessary to avoid delays. Alternatives to the canal were seriously being considered eg the NW passage and a number of alternative canal routes that avoided Panama completely. Panama relies on the income from the canal and could not afford for any of the alternatives plans to be viable and so the plan for the expansion to the existing canal system was commenced in 2007 and completed in 2016. This introduced two new sets of locks built parallel to the existing locks. Significantly, they allow ships up to 366m long, 49m wide and with a draft of up to 15m to transit the canal. The new locks were of modern design which used less water and are regarded as a safer and more reliable too.
So a Panamax ship like GLOVIS CAPTAIN can use the old locks - Miraflores, Pedro Miguel and Gatun locks to transit whereas bigger ships like DONINGTON and GLOVIS SIGMA will use the new locks at Cocoli and Agua Clara.
The canal is big business and so is generally a pretty slick operation entirely dependent on how much you have paid. The Tesla ships are normally booked in several weeks in advance and are given a pretty high priority. Delays of more than 24 hours are rare and normally we can expect the ships to start their northbound transit in the small hours of the morning and be in the Caribbean around 8 hours later.
There are webcams at the locks so you can see a ship going through. The links to the webcams are

For GLOVIS CAPTAIN, I expect her to be at Miraflores around 7am UK time tomorrow, Pedro Miguel around 9am UK time and Gatun locks around 14:00 UK time. By the time she reaches Gatun it will be daylight.
