Practical Square Rig Seamanship Sail Training Course

A number of sailing trips are organized by the Clipper Stad Amsterdam every year. Whether you are an experienced sailor or not, we are more than pleased to invite you to join our crew on one of these adventurous sailing holidays.

Twice a year the Clipper Stad Amsterdam sails across the Atlantic Ocean. This spring the first leg* of the Atlantic Ocean crossing will be from Boston to Ponta Delgada (the Azores). 

Ocean crossings are very special but this one all the more!

After last year's success and for the second time since she was launched in 2000, the Clipper Stad Amsterdam will provide a 14-day sail training course in close cooperation with Enkhuizen Nautical College. Based upon the broad experience of both the college and the Clipper crew, the Practical Square Rig Seamanship Sail Training Course will be ideal for tall ship sailors and yachtsmen as well as a wide group of sailors and classic ship lovers who like to gain experience and know-how.

* After a short stop at the Azores, the Clipper Stad Amsterdam will continue to sail across the Atlantic Ocean with Port Vendres in the South of France as the final destination.

non-stop sailing

Captain and crew will welcome you on board of the Clipper Stad Amsterdam in Boston, U.S.A. on Monday April 22nd. Boston is the capital of the state of Massachusetts and unofficially also of New England. Founded by the Puritan settlers in 1630 and well known for the Boston Tea Party, for example, this rich and “old” city located at the Atlantic Ocean has much to offer.

We will leave Boston early the next morning to start our non-stop voyage of 2100 nautical miles to Ponta Delgada (the Azores). It is time to roll up the sleeves. The sail training course begins! 

Practical Square-Rig Seamanship

Experience the deep sense of satisfaction that celestial navigation offers. Practice using a sextant to determine your position while at sea. Learn about coastal navigation when making landfall. Study the basics of weather systems, ocean currents and climatology and gain an understanding of tropical cyclones and cyclone navigation. Learn about the development of sailing ships, hulls and rigging and immerse yourself in the essentials of sailing.

Eef Willems, a teacher at Enkhuizen Nautical College and captain/owner of the sailing vessel Tooluka, will share her knowledge about navigation, meteorology and history & square-rig sailing in actual lessons and practical exercises. At the beginning of the trip, a course manual will be provided. Around three hours a day will be spent on theory courses in the Long Room. 

The captain, officers & deck crew of Clipper Stad Amsterdam will be in charge of the practical training & instructions on deck. Together with the crew you will be part of the watch to fully experience the works on a ship like Stad Amsterdam. Setting the sails, keeping lookout, setting the course or standing watch. The three shifts are called the Red Watch (from 12- 4 AM and PM), the White Watch (from 4-8 AM and PM) and the Blue Watch (from 8-12 AM and PM).

The overall program will be concluded with a ceremony and presentation of a certificate of attendance.

Arrival at São Miguel

Arrival in Ponta Delgada (the Azores)  is scheduled for late afternoon on May 6. The town is located on the south coast of the island São Miguel which in turn is part of the islands group of the Azores and easily accessible by plane. The fortress of Sao Bras and the main church Igreja Matriz de Sao Sebastiao are two buildings in the city centre with an important historical value. There is a great view of the harbour head and of aircrafts arriving from the town's harbour front promenade where locals like to meet. In clear weather, the (non-active) volcano Do Fogo can be seen. 

São Miguel, the "nature island", is the largest island of the Azores archipelago and has the most inhabitants. The crater lakes, the rugged coastline and the wonderful green nature make this a fantastic island to stay for a few days.

After 14 days at sea learning all about sailing a full-rigged ship, you will set foot ashore again. This unforgettable sailing experience has come to an end. Time to explore Ponta Delgada and/or the island São Miguel perhaps but not before you have enjoyed a delicious Captain's Dinner on the very last evening on board. The next morning at 10:00 there will be the inevitable farewell.

Eef Willems - Enkhuizen Nautical College

Eef Willems was originally trained to be a physical education teacher. Already at the age of 16 she started as an instructor at a Dutch sailing school. Since 1985 she has been working in the charter sailing business. Anxious about learning how to navigate with a sextant she sailed her first ocean crossing in 1987. Three years later she started teaching at the Enkhuizen Nautical College after having succesfully completed several charter sailing diplomas. The combination of teaching students about instruments, weather conditions, rigging plus practical navigation and commercial sailing was an ideal one. Every year she sails with guests on her own yacht "Tooluka" to Antarctic or Arctic waters for six months and works as a Lecturer (Coastal and Celestial) Navigation at the Enkhuizen Nautical College during the remaining months. From 2001 to 2004 she worked as 1st officer on the Clipper Stad Amsterdam.

Moritz Kuhlenbäumer - Clipper Stad Amsterdam

Moritz has sailed and operated traditional sailing ships since 1992. After two years as a deckhand and several years as a skipper on Dutch waters, he left for the Baltic Sea and the Caribbean. Moritz has sailed all over the world on a variety of large sailing ships and in almost every thinkable position: sailor, engineer, nautical officer and captain.

Between 2007 and 2012, Moritz sailed on the Clipper Stad Amsterdam as the second officer for one year and as the first officer for four years. In June 2015, he became one of the two captains on board the Stad Amsterdam.
