The Glossary

Yacht charter,
in plain words.

51 terms — APA, beam, charter party, gangway, MYBA, Posidonia, tender, more — defined the way the office actually uses them. Updated as terminology evolves.

A3 terms
Aft
Toward the stern (back) of the yacht. The aft deck is the back deck — typically where dining and lounging happen.
Anchorage
A sheltered location where a yacht can drop anchor and remain stationary. Anchorages have variable depth, bottom type (sand, weed, rock) and wind shelter.
APA (Advanced Provisioning Allowance)
A separate budget — typically 25–35% of the base charter rate — that the captain manages on the charterer's behalf for fuel, dockage, provisions, drinks and incidentals. Settled with receipts at the end of the charter; unspent APA is returned.
B6 terms
Beach club
A fold-down or low-set platform at the stern of a yacht, used as a swimming and lounging deck at water level. The defining feature of modern superyachts.
Beam
The width of the yacht at its widest point, measured in metres. A wider beam means more interior volume for a given length.
Berth
(1) A marina mooring spot for a yacht. (2) A bed on board.
Bimini
A canvas cover providing shade on the aft deck or flybridge — essential equipment in Mediterranean summer.
Bosun
A crew member responsible for the exterior of the yacht — deck equipment, water toys, tender operation, swim platform setup.
Bow
The front of the yacht. The bow lounger / bow sunpad is the forward sunbathing area.
C5 terms
Captain (or Skipper)
The crew member responsible for navigation, safety and command of the yacht. On day charters, often the only crew. On larger yachts, leads a crew of 3–10.
Catamaran
A multi-hull yacht with two parallel hulls. Wider beam, more deck space, shallower draft than a single-hull motor yacht of the same length. Common in the Caribbean; less common in the Mediterranean charter fleet.
Charter party (contract)
The formal charter contract between the charterer and the owner (or central agent). Industry-standard contracts include MYBA, ASA and CYBA forms.
Crew
The professional staff on board — captain, mate, stewardess, chef, bosun, engineer. Crew size scales with yacht size: typically 2 on a 15m, 3–4 on a 25m, 6+ on a 35m+ superyacht.
Cruising speed
The speed at which a yacht is comfortably and efficiently run, typically expressed in knots. Not the same as top speed (which is fuel-intensive).
D3 terms
Daily rate
The base price quoted per 24-hour period of charter. Excludes APA, fuel (on day charters), and tip.
Day charter
A single-day yacht rental — typically half-day (4 hours), full-day (8–10 hours) or sundowner (3 hours). No overnight aboard.
Draft
The vertical distance between the waterline and the deepest point of the yacht's hull. Determines which anchorages and harbours a yacht can enter.
E1 term
Embarkation
The moment of boarding the yacht at the start of the charter. Typically scheduled between 10:30 and 14:00; takes about 20 minutes from the pontoon.
F1 term
Flybridge
A second helm and lounging area above the main deck — typically with sun pads and a second helm station. Defining feature of mid-to-large motor yachts.
G2 terms
Galley
The yacht's kitchen — typically equipped with full chef-grade appliances on yachts 20m+.
Gangway
The ramp or steps used to board the yacht from the dock or tender.
H2 terms
Helm
The yacht's steering station — typically on the bridge (main helm) and on the flybridge (upper helm).
Hull
The main body of the yacht below the deck.
K1 term
Knot
A unit of speed equal to one nautical mile per hour (1.852 km/h). A 'cruising speed of 18 knots' is roughly 33 km/h.
M2 terms
Mooring buoy
A fixed buoy in an anchorage that yachts can tie to instead of dropping their own anchor. Often used in Posidonia-protected areas.
MYBA (Mediterranean Yacht Brokers Association)
The standard contract framework used for Mediterranean charters. MYBA contracts define APA, cancellation, weather clauses and liability terms.
N1 term
Nautical mile (nm)
A unit of distance used at sea, equal to 1.852 km or 1.151 statute miles. The distance from Marina Ibiza to Espalmador is ≈ 18 nm.
O1 term
Owner-direct
A charter booked directly with the yacht owner (or their captive office), with no intermediating retail broker. Typically 10–15% cheaper than retail broker rates.
P3 terms
Pitch (pitching)
The fore-and-aft rocking motion of a yacht in waves. Larger yachts and stabilised yachts pitch less.
Port
(1) The left side of the yacht when facing forward. (2) A harbour or marina.
Posidonia
A protected seagrass species native to the Mediterranean, particularly abundant around Ibiza and Formentera. Anchoring is restricted in Posidonia meadows; modern Posidonia-friendly anchoring methods are now standard.
R1 term
RIB (Rigid Inflatable Boat)
A boat with a rigid hull and inflatable tubes around the gunwale. Used as a tender, a day-charter, or as a fast sport boat. The Speedy Gonzales in our fleet is a 21ft BRIG Eagle 650 RIB.
S12 terms
Salon
The main interior lounge on a yacht — typically with sofas, a dining table, AV. The yacht's living room.
Seakeeper
A brand of gyroscopic stabiliser used to reduce roll motion both underway and at anchor. Defining comfort feature on modern mid-size yachts.
Skipper
Informal name for the captain — used most often on day-charter yachts where the skipper is the only professional crew.
Sport flybridge
A flybridge motor yacht with a sport-oriented hull — faster cruising speed than a traditional displacement flybridge, with the same exterior features.
Stabiliser (zero-speed)
A mechanism (fin or gyroscopic) that reduces roll motion. 'Zero-speed' stabilisers work at anchor as well as underway — the marker of comfort for long lunches and overnights.
Starboard
The right side of the yacht when facing forward.
Stateroom
A guest cabin on a yacht — typically with ensuite shower and head.
Stern
The back of the yacht. The stern platform / beach club is the lowered swim and lounging deck at water level.
Stewardess (stew)
Interior crew responsible for service, housekeeping, table dressing and discreet guest support. Typically two on a 25m yacht, three or more on a 35m+.
Sundowner charter
A short (typically 3-hour) evening charter ending around 22:00, with a focus on the sunset hour at anchor. The office's most-quoted short format.
Superyacht
A yacht over 24 metres (78 ft) in length. The line is technical — used by classification societies — but commercially also implies a level of crew, service and amenity.
Swim platform
A small deck at the stern at or near water level, used for swimming and tender boarding. On modern yachts this often folds down to become a beach club.
T1 term
Tender
A smaller boat carried on board the main yacht — used to ferry guests to and from the shore when at anchor, or as a B-roll vessel for photography.
V1 term
VAT (charter VAT)
Value-Added Tax on charter — in Spain, currently 21% on the charter base rate for European-flagged commercial yachts. Some non-Spanish-flagged yachts attract lower VAT under specific regimes; the office handles the structure.
W4 terms
Waterline
The line on a yacht's hull where it meets the surface of the water when properly loaded. The 'length at the waterline' (LWL) is one of two main length measurements.
Watermaker
An on-board desalination unit that produces fresh water from seawater. Standard on yachts 24m+; allows charters at anchor without marina top-ups.
Weekly rate
The base price quoted per week of charter. Industry standard for charters of 6+ days, expressed in EUR or USD. Excludes APA and tip.
Wind shelter
The degree to which an anchorage is protected from wind in different directions. A cove 'sheltered from W' means the anchorage is calm in westerly winds but exposed when the wind comes from another direction.
Y1 term
Yacht class
The categorisation of yachts by size, style and function. Common classes: dayboat (11–14m), sport (15–18m), flybridge (19–28m), superyacht (28m+).
