Being Safe on a Sailboat Sep 18

On a sailboat there are a few safety features that should definitely be installed. Fire alarms should be installed on a sailboat, below deck. It is equally as important to test this boat fire alarm once a month to make sure it is working adequately and properly. Often, fire alarm batteries run out of juice and leave sailors unknowingly vulnerable. The fire alarm which is purchased and installed should definitely be loud in pitch when going off. This will ensure that it will be loud enough to hear all around the boat.

To supplement the fire alarm, there should be a carbon monoxide detector installed as well. Poisoning by carbon monoxide happens annually to hundreds of people. The most deadly aspect of carbon monoxide is that it is odorless, and even those with a keen nose will miss its presence. There should be one installed in every sleeping area, galley, and confined space to maximize coverage and protection for the crew. Installing a carbon monoxide detector will provide early detection of the situation and prevent needless health injuries.

The interior of the boat should be well lit. Utilize boat interior lighting which is cost beneficial. There is not a limitation in selection as the types include LED lights which can be mounted on the ceiling or wall. There are smaller halogen types lamps which can adjust direction so light can be cast where it is needed. This latter type would be ideal for reading. It is also important of course to get a waterproof design. For smaller spaces and other situations, keep a powerful flashlight aboard. Some flashlights even come with built in FM radio.

Beyond safety within the sailboat, the exterior of the boat should also be well lit with boat exterior lighting. These lights are used also for navigational purposes. The best type will be the LED type, since they use half the energy and have a long life. The types and models of external lights that are chosen is going to vary on the specific length of the boat. When it comes to selecting the exterior lights, the visibility should be at least two miles. Certain situations are going to call for a floodlight to be aboard the sailboat.

A generator on board would possibly be a good idea as well. A worthwhile and especially efficient generator needs to be purchased. This may cost a little bit more, but the long term benefits will eventually make themselves clear. There needs to be specific features installed on a boat for safety purposes. It becomes very clear to those who actively go sailing that maintaining safety on a boat is just as important as maintaining the boat itself.

National Offshore One-Design Regattas in 2009 Sep 14

Placid waters, a cool breeze, and azure blue skies is a weather outlook that can only be conjured by the imagination. When Sperry Top-Sider Offshore One-Design (NOOD) Regattas take place this year, these are precisely the types of days which will be coveted. Almost all of these NOOD Regattas were plagued with some weather issues and delays last year. Hopefully this year’s prospects will improve and everyone will get to enjoy a remarkable weekend of sailing and racing.

The Sperry Top-Sider Chicago NOOD Regatta commenced on June 19th until June 21st in Chicago, IL. This NOOD Regatta, hosted by the Chicago Yacht Club, is known to place sailors in the turbulent Lake Michigan waters, and give them the opportunity to measure up their skills directly against fellow sailors without attention to the different designs between sailboats. Major entries in racing classes for this year’s fleet included Beneteau 40.7, Great Lakes, J/105, and Tartan Ten boats.

On July 23rd until July 26th the Sperry Top-Sider Marblehead NOOD Regatta was underway in Marblehead, MA. Huge crowds annually flock to this Regatta compared to the other NOOD Regatta locations in the country. This year is not any exception, taking place in the Massachusetts Bay waters, the Marblehead Racing Association expected a turn out of over 1,000 sailors. A few of the fleet sailing in Marblehead will include boats from Sonar, Town Class, Viper 640, and J/105 classes.

Hosted by the Larchmont Yacht Club the Sperry Top-Spider Larchmont NOOD Regatta is taking place in September on the 12th and 13th in Larchmont, NY. This NOOD Regatta held by the Larchmont Yacht Club, one of the most prestigious yacht clubs in the nation, attracts many sailors to its unique and special waters. These are the same waters that last year caused quite a stir when winds directions shifted suddenly as much as 50 to 60 degrees prompting a few sailors to react fast or risk getting nudged off course. The fleet for this year includes boats from Farr 40, Express 37, Shields, Etchells, and many more classes.

Last year, damage from Hurricane Ike resulted in the cancelation of the 2008 Sperry Top-Sider Houston NOOD Regatta only a few days before it was scheduled to take place the weekend of the 19th. This year’s Regatta takes place from September 25th to September 27th in Seabrook, TX. Be on deck and at the ready to raise those boat anchors because it can be surmised that the Houston Yacht Club is itching for a wicked revival. Pleasant skies and steady waters will definitely be the first request.

Whether it be a venue hosted by a local Yacht Club or sailing for pleasure, it will be foolish to miss out on the NOOD Championship which is taking place in Tortolla in the British Virgin Islands November 7th to November 12th. If last year’s NOOD Regattas were any indication, load up on boat supplies and start yearning for that perfect day, because this year’s Sperry Top-Sider NOOD Regatta season will certainly be full of surprises.

Using Natural Powers When Sailing Sep 10

On a calm and clear day, the water and wind will be moving in the same direction. Movement is difficult in this situation as there is not a godo amount of energy to be extraced. There is a capture of energy from the wind and water that is created by the diference in motion. The sailboat captures this energy by utilizing the sail(s) and the hull(s).

The difference in direction between the sailboat and the wind is the relative or apparent wind. A sail uses this apparent wind and generates lift. This is an example of an airfoil, and using Bernoulli’s Principle the airfoil creates lift much like an airplane does. In fact, depending on the orientation of the sailboat, its point of sail, and its design it could conceivably obtain a speed faster than the true windspeed.

Using the sail, the boat will be able to move in the water. If direction cannot be determined, it's useless to move around in the water alone. To help direct the boat an underwater component is required, such as a centerboard, underwater foil, keel, or even the hull itself can be employed. Movement can be acheived in any direction except directly into the wind with the sail and underwater component.

The boat's movement relative to the true wind ranges from 35 degrees to 80 degrees and is called the tacking angle. Using a 35 degree tacking angle, on either side of the wind, a sailboat could cover over 290 degrees of the boat compass. Sailing into the wind can be accomplished indirectly by sailing close-hauled, about 45 degrees, and then tacking and sailing in a zigzag fashion. There is a relationship built between the sail and underwater component to move the boat in a specific direction.

Understanding the dynamics between capturing and using the energy from the motions of wind and water can help answer the following questions:

1)How do sailboats move?

2)How can a sailboat sail upwind?

3) How will a boat sail faster than the wind?

Most sailors are not physicists but they are undoubtedly cognizant of the physical principles that govern basic movements in the water when sailing. These principles allow the boat and its crew to move in the water.
