About Us

If the heart and soul of the Sea|mester experience are the students and crew, then the body would have to be Argo, Ocean Star and Vela, our three world-class schooners.

Over the course of a voyage, the vessel becomes much more than just a mode of transportation, just the classroom or even just a home. Our students often tell us that the vessel in many ways becomes part of the team, part of themselves. Taking pride in how she looks, how she feels the vessel becomes as equally important as any one of the living crew.

While our vessels vary in design and voyage, it’s important to remember that when they are en route, it’s due to students taking charge and trimming the sails, monitoring all systems and charting courses. By harnessing the power of sailing, Sea|mester hopes that these vessels become an agent of growth for each and every student.

Completed in 2006, Argo is an expertly designed 112-ft two-masted staysail schooner with room for 26 students and 7 staff.

Argo was designed and built to circumnavigate the world. This means that every 90-day trip she embarks upon, a fresh batch of students faces the challenge of spending many days or weeks at sea while crossing one of the world’s oceans. For those looking for a genuine blue water experience, then Argo is the perfect vessel for you.

When we built Argo we did so with safety, dependability and ‘trainability’ in mind. We often refer to her as a “Big, Little Boat” meaning that we designed her systems in such a way that they are easy for students to understand and operate. Since our goal is to have students quickly reach the point where they are running the vessel, trainability is an important factor

Also a two-masted schooner, Ocean Star sits at 88ft overall and has sail plan that differs from Argo in that she carries a gaff on her foresail. Designed and built in the USA, she was first launched in 1991 then was added to the Sea|mester fleet in 2000. Ocean Star accommodates 16 students and 4 staff.

Rather than crossing oceans as a focus, the voyages run aboard Ocean Star are better suited for those looking for more of a near coastal sailing experience and, as a result, these programs tend to spend more time exploring ashore and in almost all cases, offer more opportunities for scuba diving and scuba certifications.

Launched in June 2020, S/Y Vela is built to the same basic plans as Argo. At 112-ft overall, Vela is a two-masted staysail schooner with room for 26 students and seven staff.

When we first designed Argo, we did so with safety, dependability and ‘trainability’ in mind. Vela is no different, so think of her as Argo 2.0! Thanks to her designer, Bill Langan, the original plans were so good we only had to apply subtle changes to Vela. Most involve replacing mild steel with stainless in some of the hard to reach places. These modifications, we hope, will further increase our ability to maintain the vessel in tip-top condition during her rigorous ocean-going schedule.

Robertson & Caine 4800

(Optional Chartered Vessel)

4600 Sailing 768x768

This is a true blue-water cruiser featuring a self-stacking mainsail with integral sail cover, roller-furling genoa, and twin 55 hp diesel engines. An electric windlass with handheld remote makes anchoring easy. The raised helm station is at the forward end of the spacious cockpit and above the cockpit’s hardtop roof, providing 360 degrees of visibility. A hardtop bimini shades the helm. The cockpit has walk-through access to the swim platforms, a full electronics package that includes a color chartplotter and autopilot, stereo/CD player speakers, a large table, and lots of seating. A wide door opens to the saloon.

The saloon features a U-shaped settee and a large dining table that converts to a large berth at night. There’s also a flat screen TV/DVD player. The galley has all amenities and plenty of counter space. The galley includes a 2 door front-opening fridge/freezer. The yacht has four double staterooms with dressing areas and en-suite electric heads and separate shower stalls, and forward in each hull are single berths. There is ample storage space throughout. Three separate air-conditioning units keep the cabins cool and comfortable, and numerous opening ports and hatches provide superior ventilation. The yacht is equipped with a powerful generator. This is truly a vessel worthy of our Caribbean sailing adventures.
