Janssonius is the sister vessel of Hondius, and she is among the most structurally fortified and technologically advanced polar cruise ships on the seas. Janssonius fully complies with the mandatory requirements of the Polar Code as adopted by the International Maritime Organization (IMO) for safe and environmentally sound ship operation in the polar regions.

One deck is reserved for multi-language lectures and presentations in a large observation lounge as well as in a separate lecture room. Although it is elegantly designed in stylish mid-century modern décor, this vessel remains faithful to the cozy and informal atmosphere characteristic of our expeditions.

It is our philosophy to keep sea time short so that we can focus instead on fast, effective access to shore and near-shore activities. To give you the maximum contact with the nature and wildlife you traveled so far to see, we employ a tough fleet of rigid-hull inflatable Zodiac boats that guarantee swift and safe landing operations for the passengers. Janssonius has three separate gangways and a sheltered indoor Zodiac boarding area that can also be used for special outdoor activities, such as kayaking.

Janssonius is equipped with two main engines capable of powering the vessel up to 15 knots.

Please be aware that a small number of cabins may have a partially obstructed view due to the size of the windows and the design requirements of the ship. For example, some windows may be partly obstructed in the lower half by a gangway.

Dates & Rates



Age and Nationality

Passengers on a typical voyage range from their 30s to their 80s – with a majority usually from 45 – 65. Our expeditions attract independent-minded travelers from around the world. They are characterized by a strong interest in exploring remote regions. The camaraderie and spirit that develops aboard is an important part of the expedition experience. Many departures have several nationalities on board.

Dress Code

In keeping with the spirit of expedition, dress on board is informal. Bring casual and comfortable clothing for all activities. Keep in mind that much of the spectacular scenery can be appreciated from deck, which can be slippery. Bring sturdy shoes with no-slip soles and make sure the parka is never far away in case of the call “Whales!” comes over the loudspeaker and you have to dash outside. Wear layers since it is comfortably warm aboard the ship – and often cold on deck.

Currency & Payment

Refreshments from the bar and souvenirs will be charged to your cabin. The day before departure you can settle your bill with the Hotel Manager and pay by credit card (Visa or MasterCard) or cash (Euro, or in some cases Dollar). We do not accept cheques of any kind. The prices and standard currency on board our vessel is the Euro. Other currencies may be accepted at the discretion of the hotel manager at prevailing rates.

Electric Current

The electrical supply aboard the ship is 220v, 60Hz. Electrical outlets are standard European with two thick round pins. You may need a 220v/110v converter.


The customary gratuity to the ship’s service personnel is made as a blanket contribution at the end of the voyage which is divided among the crew. Tipping is a very personal matter and the amount you wish to give is at your discretion. As a generally accepted guideline, we suggest 8 to 10 Euros per person per day. It is better for the crew, if you can give them cash.

Non-Smoking Policy

On board our vessels we have a non-smoking policy. It is prohibited to smoke inside the ship. You can smoke in the designated smoking areas. Please respect the wishes of non-smokers.

Your Physical Condition

You must be in good general health and you should be able to walk several hours per day. The expedition is ship-based and physically not very demanding. Although we spend as much time as possible ashore, you are welcome to remain aboard the ship if you like. To join most excursions, you must be able to get up and down the steep gangway from the ship to the water level to board the Zodiacs. Staff will assist you in and out of the boats. This will become progressively easier with practice. Ashore it can be slippery and rocky. You are travelling in remote areas without access to sophisticated medical facilities, so you must not join this expedition if you have a life-threatening condition, or need daily medical treatment.
