Q

Sailing in the Groove and the 3 references

A

The sailing angle where you’re making the best progress “windward” (toward the wind). References are your speed, the angle of heel, and the telltale on the jib

Sailing too close to the wind will cause sails to luff, and the windward telltale to flutter. Heading back away to fill the sails back up again

Sailing too far away from the windward direction will cause you to heel too much, and the leeward telltale will flutter

Lines when you’re tying up at the dock

A

Bow and Stern lines - attached to cleat on dock from each end of the boat. Keep boat close to dock, but doesn’t prevent backward/forward motion

Spring lines - prevent backward/forward motion. Referred to according to where they go from the cleat on the boat. “Aft Spring line” (or Forward Quarter Spring line”) goes from a forward cleat on the boat back towards a cleat on the dock

Always secured with a cleat hitch

25
Cunningham
system used to add tension to the luff in the sail. It changes the shape to affect how much power it give you Light wind = need more power = want fuller sail shape = Ease the Cunningham, Ease the Outhaul Strong wind = want to control power = want flatter shape = Tighten the Cunningham, Tighten the Outhaul Ease Cunningham when heading downwind to get baggier sail, tighten it heading upwind
26
Traveler
Track that controls sideways movement of the mainsail Along with mainsheet and boom vang control height of boom and leech tension in sail
27
Wind shifts - forcing you to head up or bear away
"Lift" - Wind shift that comes towards your stern that forces you to head up "Header" - Wind shift coming towards your bow that forces you to bear away Backing - counterclockwise shift in wind Veering - clockwise shift in wind Page 54
28
Bowline
Puts a non slipping loop at the end of a line
29
Figure 8 Knot
Stopper Knot | Tied on the end of a line to prevent it from slipping through a fitting
30
Square Knot
* Used only for sail lashings | * Can be difficult to untie
31

32
Clove Hitch
* Used to tie a line to an object | * Not very secure
33
Round Turn and Two Half Hitches
Uses a loop to secure a line to an object
34
Stand On Vessel vs Give Way Vessel
Stand On Vessel - maintain course and speed, less maneuverable craft Give Way Vessel - more maneuverable, give indication of change of course obvious and early
35
Right of Way - Starboard Tack vessel vs Port Tack Vessel
Boats coming from opposite directions Starboard tack has right of way over Port tack Vessel on Port tack is the give way vessel
36
Right of Way - Leeward Vessel vs Windward Vessel
``` Boat traveling in same direction Windward Vessel (upwind) is the give way vessel and should yield to the the leeward vessel by steering behind it ```
37
Soundings
Water Depths - indicated on nav charts | Fathom = 6 ft
38
Channel Buoys
Green - Cans - Odd numbers Red - Nuns - Even numbers Red Right Return Diamond shape on chart
39
Ways of shortening Sail - powerful wind
Reefing - partially lowering the mainsail to reduce the area, should be accomplished while on close reach or Hove To with mainsail luffing Lowering the Jib - will need to compensate by steering with the tiller pulled slightly away from the mainsail because the boat will not be in balance with only the mainsail up Lowering the Mainsail - will need to compensate by steering with the tiller pushed slightly toward the mainsail because the boat will not be in balance with only the mainsail up pg 74
40
Steps during anchoring
*Take down and store the jib *Anchor line is called a rode Rode should be coiled on foredeck so it will run freely *Sail on beam reach until you are 3-6 boat lengths of where you want to drop anchor *When you are directly downwind of where you want to drop it, head into wind *As the boat comes to a stop, carefully lower anchor *After it hits the bottom, pay out line as you drift back *When you reach ideal spot, cleat off rode, ensure it's holding, and lower mainsail
41
Puffs / Lulls
Show up on water as dark moving patches Increase in wind speed and or direction for short duration Lulls - smoother areas on water , less wind strength
42
King Spoke
Reference point on the steering wheel for when the rudder is centered
43
By the Lee
Sailing on a run with the wind coming over the same side of the boat as the boom Indication - jib will start to luff, watch for boom to cross. Can correct by sailing back toward the wind "Turn tiller to boom to avoid doom" - turns you so you're more on a direct run
44
Helm's a Lee
Tacking
45
Best angle for anchor
As close to horizontal as possible, so the flukes a grab hold
46
Rode
Line or chain attached from the boat to the anchor
47
Fairlead
A fitting that guides a jib sheet back to the cockpit or along the deck
48
Tides vs current
Tides - vertical motion / Current - horizontal motion In a coastal area...when tides rise, current *flood*, when tides fall, currents *ebb* Current will run faster through narrow openings Buoys will lean in the direction of the current
49
Ahead, Astern, Abeam
Ahead, behind, to either side
50
LOA Draft LWL Freeboard
Length overall - tip to stern Distance from waterline to the *deepest* part of the boat (bottom of keel) Load waterline length-from the points where the bow and stern come out of water From the waterline to where the deck and the side of the boat meet
51
Topsides
Outer sides of the boat between the water line and the edge of the deck - "freeboard" measurement
52
Headstay vs Forestay
Standing rigging | Forward stay going to top of mast vs not going all the way to the top
53
Shrouds and spreaders
Shrouds - from top to edge of deck | Spreaders hold them out towards the top of the mast
54
Running rigging
Halyards and sheets attached to sails
55
Backing the sail
Physically holding the job out *against* the wind to get the boat moving Back the jib to the same side you eventually want to be tacking on
56
Controlling heel
Ease mainsheet
57
Hardening up
Turning towards the wind
58
Maintaining speed
Keeping airflow "attached", flowing evenly and smoothly over sail Poor sail trim will cause it to become "detached" and turbulence occurs due to angle airflow makes with sail (angle of attack) The smaller the angle, the longer the wind will maintain contact with the sails surface as it makes its way from the luff to the leech of the sail
59
Bernoulli's principle
As velocity increases, pressure decreases, creating lift at right angles to the sail in the leeward direction. Changed concept of wind pushing to sail pulling
60
Adjustment to keep airflow moving smoothly
Ease the sail until starts to luff, the trim it in just enough to stop the luff
61
If angle if attack is too wide
You're going to run out of lift, causing boat to heel over and slow down. Easing the mainsail out will decrease the angle and reduce the
62
Circulation effect
As wind passes over the sail it spilts, with more velocity over the leeward side than the windward side
63
The Slot
The space between the windward side of the jib and the leeward side of the main As air passes over the windward side of the jib, it bends and pushes air to the leeward side of the main Slot acts like an accelerator, so there's increased velocity in the slot, which increases suction The jib works to help improve the angle of attack on the mainsail. Directs air efficiently When you're sailing upwind, always strive to keep the slot open. If you ease the mainsail out before the jib, it will decrease the size of the slot and improperly bend the wind. Always ease the jib first
64
Heeling
More hull in the water, causes friction which slows you down Sideways lift is stronger than forward pull Sail area at the top of mast masked boat heel more, that's why reefing helps
65
On a run...jib and lift
Jib is ineffective, blocked by the main, often rolled up to prevent it from flapping No forward pull, only push Wind is bending around both sides of sail and turning into turbulence on the leeward side
66
Telltales on jib
Windward side fluttering- you're heading to much into the wind, or your jib need to be trimmed in Leeward side fluttering - you're steering too far away from wind, or your jib need to be let out When sailing, trim the jib in, and then ease it out until both telltales are flowing together
67
Sailing wing and wing
When sailing on a run, pulling the jib over to the other side so wind is pushing both sails Can hold it out manually, or rig a pole between mast and clew of jib to hold it out Helps increase normally slower speed on a run
68
Jib Leads
Always change jib not in use first, then tack and change other one When block is too far forward, most of the force on the jib sheet is *down* causing foot of jib to be too loose and leech too tight (*bottom*of the sail balloons out and starts to luff) When block is too far aft on track, most of the force on the jib sheet is *back/ horizontal * causing foot of jib to be too tight and leech too loose (*top* of the sail becomes too loose and starts to luff) Head into wind. If top luffs first, move block forward, if bottom luffs first, move block aft. Jib should flutter along full length of luff
69
Sail design terms
Chord - distance from leech to luff Camber - belly formed when filled with wind Draft - distance from chord to deepest part of the camber. Controlled by the outhaul (lower third) and backstay (top 2/3) on mainsail. Cunningham and halyard control the draft backward or forward
70
Weather helm
A feeling that the boat wants to head up and towards the wind
71
Apparent wind
Heading on a close hauled course - apparent wind is more than true wind On a reach or a run, apparent wind is less then when close hauled
72
Apparent wind on a run
Apparent wind is less, traveling with you Apparent wind is always forward if the true wind unless true wind is dead ahead or astern On a run, sail at slight angle to gain more speed and avoid an accidental jibe
73
Lee and weather helm
Balance of boat - well balanced if it doesn't turn when you let go of tiller under sail When letting go of tiller under sail if it bears toward windward, you're feeling weather helm. If it turns leeward, you're feeling lee helm
74
Center of Effort and Center of Lateral Resistance
COE - combined geometric center where force is exerted on sail system CLR - combined center of forces of underwater areas- bottom of helm, keel and rudder Boat is in balance when the two are aligned The two will resist each other Weather helm will occur when CE moves aft of CLR - sailing with just the main- CE concentrated further back, boat turns toward wind Lee helm will occur if you sail with just your jib, because CE is fore of CLR - boat will turn away from wind - *no benefits*
75
Center of bouyancy | Center of gravity
COB - center of all the water your hull displaces, will move as you heel COG - remains in one spot - on the keel Boat upright - they're in line As heels, they move apart. COG is pulled down, COG is pushed up If you heel so much that spreaders are in the water, sails are ineffective. Quickly take down or completely luff sails to allow keel to right the boat Boat that always rights itself has positive stability COB and COG - largest distance
76
Displacement boat
Heavy, deep keel Hull speed - maximum speed out of wind power Hull speed in knots - 1.34x sq root of LWL in ft Keelboat can not travel faster than the wave it creates - Higher waves have longer wavelength and boat will go faster
