Mar 15 Program: Wind – Given by Kim

leave a comment »

In the spirit of Spring Break, the evening’s program was a “field-trip”-style fun exercise, in which we went outside and observed how certain objects are designed to travel in unique paths relative to the wind, rather than just blowing away from the wind. We flew kites and threw boomerangs and frisbees to closer study the phenomenon of lift (why kites, helicopters, and airplanes rise in the air, why boomerangs travel in circular paths, and why sailboats are able to sail upwind). Okay, so obviously we all already know how lift works (click here if you don’t: https://ship502.wordpress.com/2010/03/02/mar-1-racing-program-some-basics-given-by-nick/), but since school was out, we just wanted a fun activity that didn’t require any heavy-duty thinking.

While there wasn’t enough wind to keep the kites flying on their own, we created our own by running with the kites to keep them aloft. As for the boomerang, nobody’s attempt at a complete circular path was successful. After a bit of research, I discovered that we had been doing everything correctly, except we had been throwing the boomerang straight into the wind (apparently the boomerang works best when thrown 90 degrees to the wind). However, I’m not sure this bit of information would have helped us.

Further reading on how a boomerang works/how it is supposed to be thrown:

While we already understood the basic principles of lift, this program gave everybody a better feel for how these priniciples apply to sailing and boatspeed.

Mar 8 Program: Time, Bells, & Watches – Given by Kim

leave a comment »

Two Mondays ago, (I apologize for getting these minutes out so late) we had quite an eventful meeting. The main matters of interest from the evening included discussing the geocache “Race to the WIK 2010,” voting on a Long Sail destination, learning about the bell and watch system used on sailing vessels, and starting timed knot races.   

This first order of business was receiving the new geocache travel bug for the Race to WIK 2010. For those of you who don’t know what geocaching is, “geocaching is a high-tech treasure hunting game played throughout the world by adventure seekers equipped with GPS devices. The basic idea is to locate hidden containers, called geocaches, outdoors and then share your experiences online” (quote from geocaching.com). You usually place a small object of some sort into the cache and trade for another small object. The travel bug is a tag attached to the object and is used to track the movement of the geocache object. The purpose of the Race to WIK 2010 is to get our team’s bug to the Koch Cup before any of the other teams. Both of our Koch Cup teams, Nick/Kelly and Eva/Sofia, will participate in the geocache race. Nick/Kelly received their travel bug first and selected, as their geocache object, a rubber duck. This pirate-clad duck (pictured right) underwent the rigorous and top-secret naming procedure to become “Spo,” short for “Spoil Area.” Click “Ducks” under “Pages” in the sidebar to see our other rubber duckies.

Next, we voted on our Long Sail destination for this summer which is… PADRE ISLAND! yay! Long Sail will be June 6-13.   

The program for the evening discussed “Times, Bells, and Watches.”   

The watch system allows a sailing crew to rotate duties and operate a vessel non-stop over a long period of time. A watch is usually a four hour period of time in which a crew member has a specific activity he or she is supposed to be doing.

The watch system began when ships were powered by oarsmen rather than sails. Rowing was difficult work and one oarsmen could not row for very long without tiring. To solve this problem, an hour-glass would time a thirty-minute period, after which the rowing crew would switch off with another crew and have a thirty-minute resting period, and the cycle would repeat itself.   

Later on, ships were developed that used a combination of sail power and rowing power. This made work significantly easier on the oarsmen meaning they could row longer than before. Each shift, or “watch,” was now two turns of the hour-glass, or one hour, rather than thirty minutes.   

trireme (sail and oar)

When boats became powered solely by sail, there was much less labor-intensive work for the crew members, which allowed for even longer watches. Watches became four hours long and rather than rotating just work and rest watches, each crew member had an individualized schedule with specified watches for working (for instance being lookout or handling a sail), eating, and sleeping.   

 The Watches:   

First Watch                                           2000-2400   

Middle Watch                                       2400-0400   

Morning Watch                                     0400-0800   

Forenoon Watch                                   0800-1200   

Afternoon Watch                                  1200-1600   

First Dog Watch*                                  1600-1800   

Second Dog Watch*                              1800-2000   

                            * Dog Watches are only two hours   

The Bells:      (each ” . ” is a ring of the bell; there are short pauses after every two rings of the bell)   

ex: Forenoon Watch:                                                                              ex: First Dog Watch:

1200          . .        . .        . .        . .   

 After the program, Kim presented the idea of having timed knot races at the end of each meeting. The goal is to have everybody be able to tie all of a list of knots in under three minutes. This will prepare our members for events such as SEAL and Rendezvous and will make sure all members know the knots for regular use, rather than quickly relearning them before a competition. However, at this meeting, we did not have time to hold a knot race…

Mar 1 Racing Program: Some Basics -Given by Nick

with one comment

These are the three most important principles every racer should keep in mind while sailing.

1. Sail Trim

When sailing upwind, the sails should be close-hauled.

To review how sails move the boat when going up wind: sails work as an airfoil. Air going around the windward side of the sail has less distance to travel and will have less speed; this creates low pressure on the windward side of the sail. Air going around the leeward side of the sail has a long, curved distance to travel and will blow across faster, creating a high pressure on the leeward side of the sail. As with the wings on an airplane, the two pressure cause a force, called lift, to push the boat in the direction of the high pressure, or towards leeward; This force to leeward is called leeway. The boat is able to move forward because the centerboard and rudder resist moving sideways against the water and will redirect the leeway force forwards. However, for all of this forwards motion, there is always some drift in the leeward direction.

Adding a jib can make the two sails more effective. If the jib is trimmed correctly, it will channel more air between the sails to go even faster around the high pressure side of the main, resulting in an even greater difference in pressures and a greater force.

If the jib is too tight in comparison to the main, it will channel its wind directly onto the back of the main sail and disrupt the high/low pressure system.

To make sure the jib is set correctly for a close hauled close, keep both side’s telltales streaming straight back. If the inside telltale is not flying straight, then the jib needs to be adjusted out. If the outside telltale is not flying straight, then the jib needs to be trimmed in.

Also adjust the jib so that there are no wrinkles in the foot of the sail.

2. Heading

When sailing upwind, you should sail as close to the wind as possible (which, as you know, is about 45 degrees from the wind). You can tell if you are pointing too high if the sails start luffing, meaning that they are not smooth and flat and may have a bubble in the luff of the sail. Remember, when close-hauled, the sails should be smooth and tight.

Keep in mind that the upwind mark might not always be directly upwind from the starting line. Sometimes the wind will shift to come from another direction, and the boat’s heading will need to be changed as well. If the wind shifts, use the tack that will provide the most direct path to the windward mark.

3. Crew Positioning

On upwind legs, most small racing boats sail fastest when perfectly balanced and flat on the water. Certain conditions can cause the boat to lean or heel in different directions. However the weight of the crew can be placed to keep the boat flat.

Because the pivot point of the boat is the centerboard, the crew should be seated as close together as possible over the centerboard. The crew usually sits forward of the jib cleat, and the skipper just behind the jib cleat. This will prevent the boat from plowing (the bow dipping lower in the water) or dragging (the stern dipping lower into the water).

Heavy wind will shift the pivot point further back, behind the centerboard; so in heavy wind, both skipper and crew should move further back, but still sit close together.

When sailing close-hauled, the boat normally heels over to leeward. To counteract this, the crew should hike out so that their bodies are parallel with the water.

Keeping the boat flat in this situation makes the boat sail faster because more of the leeway force will be converted into forwards movement. Recall that the sails create an airfoil that pushes the boat to leeward, perpendicular to the line of the boat. However, the surface area of the side of the center board resists movement in the leeward direction and redirects the force forwards. When the boat heels over, less of the centerboard surface area is resisting the leeway force and the boat will drift more to leeward.

At the meeting, we never got to learn how each of these three principles change for each different point of sail (reaching, wing-on-wing, etc.). I actually went much more in depth than we did at the meeting, so it is a lot more information (albeit much of it review material) than should be presented all at once. So ya know, oops… But I hope it was helpful nevertheless. I probably could have found real pictures for this lesson, but I find Microsoft Paint far too much fun:-) Click on the pictures to make them larger.

Tongue-twister a la Kim:

“How many tales could a telltale tell if a telltale could tell tales.”

Feb 22 Program: Compass- Given by Kim

leave a comment »

Monday’s program was about boxing the compass in degrees and in “cardinal and ordinal and beyond” directions.

Also at the meeting, the youth members had time to rethread the halyard through the Laser 2 mast. The halyard came out during last Saturday’s racing practice; more details will be posted later.

If you couldn’t come to the Monday meeting, here’s what we learned:

(click on the images to make them bigger)

Turk’s Head

Turk’s Heads are used for decoration. They can be tied around something in a tube shape or flattened into a coaster-like shape (pictured top right).

Monkey’s Fists are used when heaving a line. The knot makes the end of the line heavier which allows the line to be thrown farther and more accurately hit its target.
