It's not every day you see a gigantic superyacht weaving through the narrow canals of the Netherlands.
Thankfully photographer Tom van Oossanen was on hand to capture the astonishing scenes as Project 817, a 94-meter (310 feet) vessel built by Dutch shipyard Feadship, was transported from its Kaag Island facility to the North Sea at Rotterdam last week.
In a series of stunning images, the vessel, one of the largest to be launched in 2021, is guided through the water with tugboats, passing by houses and churches, as crowds look on in amazement.
According to Oossanen, around four to six superyachts are transferred along this route each year before going for sea trials, which usually take place in Amsterdam.
However, few are as big as Project 817, likely to be known as Viva when it officially launches.
"Everyone loves to see it."
But these maneuvers lead to serious snarl ups on land and water.

"There's only one way to go."
Some parts of the canals along the route are only a few feet wider than Project 817, which spans 44.7 feet from port to starboard, so to say the transfer required great care and attention is something of an understatement.
"This boat has been fully designed to actually fit the waterway," says Oossanen, pointing out that he's only ever seen four superyachts of this size taking this same journey.
"So they [the designers] probably couldn't add another centimeter to her length or another centimeter to her width.
"They maximized the design by using the limitations of bridges and waterways, which is quite interesting."
Feadship says the duration of a transfer is dependent on several different factors, such as the winds and bridge schedules, and can take between two to four days.
The transportation of Project 817 took around four days.
Tug boats were then attached to the pontoons on either side of the superyacht, which was also wrapped with protective foil, in order to guide the vessel through the water with precision.
By this point, it was ready to be pushed and pulled along the canals, making its way across a small bridge in the tiny village of Woubrugge, as well as Alphen aan den Rijn, a town in the west of Holland, before reaching the Dutch city Gouda, located south of Amsterdam, a few days later.
A team of five experts and a crew on board usually guide a superyacht to the sea, according to Feadship.
"They [the captains] are very experienced in what they're doing," he says.
"There's obviously a lot of money involved, so you want to do things properly.
And if you're going to rush things, things can go wrong."
It's perhaps no surprise that the transfer of Project 817 caused quite a stir on the ground, particularly while passing through the smaller villages along the way.
Some onlookers were absolutely bewildered by the sight of such a huge yacht in transit on the canal.
"People were actually asking questions like 'why would someone cruise his boat here?'" says Oossanen, who followed Viva for the first two days of the transportation.
"Obviously it's not cruising.
She's going to sea and she will never come back again."
While Oossanen has photographed many such transfers, he stresses that no shoot is the same, and he's constantly trying to come up with new ways to showcase the vessels.
"Every boat is different," he says.
"It's always the same route, but I always try to find different angles.
"It's a challenge to picture it in a different way. I'm really glad this one worked out so well."
Feadship opened a new facility in Amsterdam that has the capacity to build superyachts up to 160 meters long.
And a 140-meter dry dock has been fitted to its Makkum shipyard, allowing for the construction of yachts with wider beams.
The Dutch government has also confirmed plans to widen the locks at nearby Kornwerderzand, which ultimately means larger vessels will be able to sail directly from Makkum to the North Sea in the future.
"They can easily build up to 160 meters in a new facility, so why would they still transfer such a big boat through all these canals and go through all the hassle?" notes Oossanen.
"Knowing the inside information, I think seeing a 94-meter doing this route is either going to take a while, or might not happen [again] at all."
Designed by Azure Yacht Design & Naval Architecture and De Voogt, Viva, which features a hybrid propulsion system, is a particularly striking sight to behold thanks to its pearl-white livery.
"By the time she's fully unwrapped, washed and cleaned, you're going to see her in the sun and she's going to twinkle like a star," he adds.
Feadship confirmed to CNN Travel that the vessel successfully reached Rotterdam and will soon be ready for sea trials.
Project 817 will be closely followed by a number of significant superyachts currently under construction in the Netherlands.
Heeson's 60-meter Project Falcon, the shipyard's largest steel yacht so far, is due to launch in the coming months, while Oceanco's 117-meter Project Y719 is also expected at some point this year.
Meanwhile, work is still underway on Feadship's 95-meter Project 1009, which is currently in the final stage of construction.
