shrouds and help to support the mast. 
Stall:  a  sail  stalls  when  the  airflow 
over it breaks up, causing the boat to 
lose way. 
Stanchion:  upright  metal  post  bolted 
to  the  deck  to  support  guardrails  or 
lifelines. 
Standing  part:  the  part  of  a  line  not 
used when making a knot; the part of 
a  rope  that  is  made  fast,  or  around 
which the knot is tied. 
Standing  rigging:  the  shrouds  and 
stays that are permanently set up and 
support the mast. 
Starboard:  right-hand  side  of  a  boat 
looking forward (opp. of port). 
Starboard  tack:  a  boat  is  the 
starboard  tack  when  the  wind  strikes 
the  starboard  side  first  and the  boom 
is out to the port. 
Stay: wire or rope which supports the 
mast in a fore and aft direction; part of 
the standing rigging. 
Steerage  way:  a  boat  has  steerage 
way  when  it  has  sufficient  speed  to 
allow it to be steered, or to answer the 
helm. 
Stem:  the  timer  at  the  bow,  from  the 
keel  upward,  to  which  the  planking  is 
attached. 
Sternway:  the  backward,  stern-first 
movement of a boat. 
Stringer: a fore and aft member, fitted 
to strengthen the frames. 
T 
Tack: 1, the lower forward corner of a 
sail;  2,  to  turn  the  boat  through  the 
wind  so  that  it  blows  on  the  opposite 
sides of the sails. 
Tacking:  working  to  windward  by 
sailing  close-hauled  on  alternate 
courses so that the wind is first on one 
side of the boat, then on the other. 
Tack  pennant:  a  length  of  wire  with 
an eye in each end, used to raise the 
tack  of  a  headsail  some  distance  off 
the deck. 
Tackle:  a  purchase  system 
comprising  of  rope  and  blocks  that  is 
used to gain mechanical advantage. 
Tang:  a  strong  metal  fitting  by  which 
standing  rigging  is  attached  to  the 
mast or other spar. 
Tender of dinghy: a small boat used 
to ferry stores and people to a yacht. 
Terminal fitting: fitting at the end of a 
wire  rope  by  which  a  shroud  or  stay 
can be attached to the mast, a tang or 
a rigging screw/ turnbuckle. 
Tide:  the  vertical  rise  and  fall  of  the 
oceans  caused  by  the  gravitational 
attraction of the moon. 
Toe  rail:  a  low  strip  of  metal  or 
molding  running  around  the  edge  of 
the deck. 
Topping lift: a line from the masthead 
to a spar, normally the boom, which is 
used to raise it. 
Topsides: the part of a boat’s hull that 
is above the waterline. 
Track: 1, the course a boat has made 
good; 2, a fitting on the mast or boom 
into which the slides on a sail fit; 3, a 
fitting  along  which  a  traveller  runs, 
used to alter the angle of the sheets. 
Transit:  two  fixed  objects  are  in 
transit  when  seen  in  line;  two  transit 
give position fix. 
Traveller:  1,  a  ring  or  hoop  that  can 
be hauled along a spar; 2, a fitting that 
slides  in  a  track  and  is  used  to  alter 
the angle of the sheets. 
Trim:  1,  to  adjust  the  angle  of  the 
sails, by means of sheets, so that they 
work  most  efficiently;  2,  to  adjust  the 
boat’s  load,  and thus  the fore  and aft 
angle at which it floats. 
True wind: the direction and speed of 
the  wind  felt  when  stationary,  at 
anchor or on land. 
Turnbuckle: see Rigging screw. 
U 
Under way: a boat is under way when 
it is not made fast to shore, at anchor 
or aground. 
Uphaul:  a  line  used  to  raise 
something  vertically,  e.g.,  the 
spinnaker pole.  
V 
Veer: 1, the wind veers when it shifts

controlled way. 
W 
Wake:  the  disturbed  water  left  astern

Waterline:  the  line  along  the  hull  at 
which a boat floats. 
Waterline  length  (WL):  the  length  of 
a  boat  from  stem  to  stern  at  the 
waterline.  It  governs  the  maximum 
speed of displacement hull and effects 
a boats rating. 
Weather helm: ( opp. of lee helm). 
Weather  side:  the  side  of  a  boat  on 
which the wind is blowing. 
Wetted  surface:  the  area  of  the  hull 
under water. 
Whisker  pole:  a  light  pole  used  to 
hold  out  the  clew  of  a  headsail  when 
running. 
Winch:  a  mechanical  device, 
consisting  usually  of  a  metal  drum 
turned  by  a  handle,  around  which  a 
line  is  wound  to  give  the  crew  more 
purchasing power when hauling taut a 
line, e.g. a jib sheet.  
Windage:  those  parts  of  a  boat  that 
increase  drag,  e.g.,  rigging,  spars, 
crew, etc. 
Windlass:  a  winch  with  a  horizontal 
shaft  and  a  vertical  handle,  used  to

(opp. of leeward). 
Y
