About · Captain Sirian Caldera
Hanseatic Yacht Service is a professional yacht service operated by Captain Sirian Caldera, an experienced and qualified captain and skipper. Owners and charter guests deal directly with the person who takes responsibility on board.
The work covers sailing yachts, catamarans and motor yachts, private and charter alike: taking command for a trip, moving a yacht safely to its next port, teaching owners to handle their boat with confidence, and advising on decisions that deserve a seagoing perspective.

Services
Each service is delivered personally, to professional standards, and scaled to your yacht and your plans.
20 years of charter experience in Sardinia
A qualified captain on board for owner trips, charter weeks, regattas or single passages — sailing yachts, catamarans and motor yachts alike, run with calm seamanship and complete discretion.
Your yacht moved from A to B by a professional crew: careful passage planning, continuous weather monitoring, sensible decisions at sea and a clear handover on arrival.
Practical, patient instruction on board your own yacht or a charter yacht — from confident manoeuvring under sail and engine to navigation, safety routines and short-handed sailing.
An experienced professional opinion before you commit: suitability of a yacht for your plans, equipment and safety questions, preparation for a season or a longer passage.
Discreet support in buying or selling a yacht, guided by seagoing experience rather than sales pressure, with the yacht assessed the way it will actually be used.

Yacht Transfers & Deliveries
Whether the yacht is heading to a new owner, a yard, a charter base or the start of your season, it is handled as if it were our own.
We operate throughout the Mediterranean and Northern Europe, and also undertake transatlantic deliveries. Every request is assessed individually and quoted accordingly — your route, the season and the yacht all shape the plan.
Sailing Instruction
Instruction built around you and the yacht you actually sail — practical, unhurried and always with safety as the first consideration.
Courses are held in Sardinia, with weekly offshore navigation courses. Get in touch for upcoming dates and availability.

Consulting & Brokerage
Buying, preparing or selling a yacht raises questions that are best answered by someone who has to live with the result at sea.
How we work
Every decision on board starts with the safety of crew, guests and yacht. Weather, sea state and the yacht's condition set the plan — never the schedule.

Clear communication before, during and after the trip. What is agreed is what happens, and you always know where your yacht is.
One captain, one point of contact. No agency layers, no anonymous crew pool — your yacht and your plans are treated as private matters.
