00 — The plate
A hull, drawn first
Every serious conversation about a yacht starts at the profile, because the profile
is where the compromises are visible. Length buys volume, beam buys stability, draft
buys sea-keeping and costs you anchorages. Scroll on and the drawing takes itself apart.
01 — Forward
The bow and its flare
The stem is close to plumb: it buys waterline length, and waterline length is what
sets the speed a displacement hull can hold without fighting its own wave. The flare
above it throws spray outward instead of over the foredeck — the difference between a
dry passage and a wet one.
- Buys
- Waterline, dry decks
- Costs
- Interior volume forward
02 — The sheer
One line that dates a boat
The sheer is the curve of the deck edge from stem to transom, and it is the single
line most responsible for whether a yacht looks right. A rising sheer forward keeps
the bow out of the water and reads as traditional; the flat sheer of the last two
decades buys volume and interior headroom, at the cost of that lift.
- Read it for
- Era, intent
- Not for
- Build quality
03 — Below the line
Draft decides where you sleep
The depth from waterline to the lowest point of the hull — the specification most
likely to change your holiday. Deeper is steadier in a seaway; shallower lets you into
the bays and creeks the deep boats only read about.
- Deep
- Sea-keeping
- Shallow
- Anchorages
04 — Main deck
Where the week is actually spent
Saloon, dining and usually the galley, set low where motion is least. The window band
is not only a view: on a well-drawn boat the glass is deep enough to hold the horizon
while seated, which is what actually keeps people comfortable.
- Motion
- Lowest aboard
- Check
- Seated sightline
05 — Flybridge
The deck that sells the boat
An upper helm, shade, and the deck most people picture when they picture a yacht.
It is also the highest weight aboard, so its size is a naval-architecture decision
before it is a lifestyle one. The mast sets the air draft — which decides the
bridges you can pass.
- Gains
- Deck, view
- Costs
- Stability, air draft
06 — Aft
The garage and the beach club
The volume aft holds the tender, the toys and, increasingly, a platform that folds
down to the sea. It is the part of the boat that changes a week the most and the part
least visible in photographs — so ask what actually fits, whether launching needs
calm water, and how long the crew take to put it all away.
- Ask
- Tender length
- Ask
- Sea state to launch
