Ready to Sleep
People, who say they sleep like a baby, usually do not have one. The same analogy can be made about Towboaters. Any Towboater that tells you he sleeps like a baby is most likely talking about his time off of the boat. With our six hours on, six hours off watch schedule, sleep becomes a valuable and critical component when it comes to your health plus the safety of the vessel and crew.
Getting restful sleep is as an important part of the job as anything else. All the PPE in the world will not protect you from a lack of sleep. Let's look at the mechanics of sleep and how knowing your sleep cycles can help you get proper rest.

The Basics of Sleep.
Sleep is not merely a time when your body and brain shut off. While you rest, your brain stays busy, overseeing a wide variety of biological maintenance tasks that keep you running in top condition and prepare you for the next watch. Sleep is prompted by natural cycles of activity in the brain and consists of two basic states that you have probably heard of:
- Rapid eye movement (REM) sleep and
- Non-rapid eye movement (NREM) sleep.
During these periods, your body cycles between NREM and REM sleep. Typically, people begin the sleep cycle with a period of NREM sleep followed by a very short period of REM sleep. Dreams generally occur in the REM stage of sleep.
How long are these cycles?
The following is from the Center for Applied Cognitive Studies (http://centacs.com):
"Studies show that the length of sleep is not what causes us to be refreshed upon waking. The key factor is the number of complete sleep cycles we enjoy.
Each sleep cycle contains five distinct phases, which exhibit different brain- wave patterns. One sleep cycle lasts an average of 90 minutes:
- 65 minutes of normal, or NREM (non-rapid eye movement).
- Sleep; 20 minutes of REM sleep (in which we dream).
- A final 5 minutes of non-REM sleep.
If we were to sleep completely naturally, with no alarm clocks or other sleep disturbances, we would wake up, on the average, after a multiple of 90 minutes-for example, after 4 1/2 hours, 6 hours, 7 1/2 hours, or 9 hours, but not after 7 or 8 hours, which are not multiples of 90 minutes.

A person who sleeps only four cycles (6 hours) will feel more rested than someone who has slept for 8 to 10 hours but who has not been allowed to complete any one cycle because of being awakened before it was completed."
Use Sleep Cycles to your advantage.
It takes some practice and discipline to get your sleep cycles right. While onboard your boat, the watch system structure must be worked with to fit in a sufficient number of sleep cycles.
- Practice - Getting sleep cycles right, while working a watch system, does not happen overnight. Towboaters on a six on/six off watch schedule have to work out a sleep/awake routine that is best for them.
- Discipline - Once you find an off watch sleep pattern that works well with your body, stick to it. It is tempting to leave your routine because of distractions....TV, video games, etc. Resist at all costs and keep your sleep cycle routine going.
Remember it is not just the quantity of hours you spend in the rack, but the quality of those hours of sleep.
Eating cycles are important as w ell.
Any substantial meal during the day should be eaten before going on watch.
Eating a small snack before turning in may help. There are no specific foods that help you sleep. But, it's a good idea to avoid certain foods before hitting the rack. Here are a few things to keep in mind:
- Don't go to bed hungry. A light snack before bedtime can keep hunger pangs from waking you up. For example, have a bowl of oatmeal with milk. If you have diabetes, discuss nighttime snacks with your doctor.
- Avoid large, high-fat meals after getting off watch. Also avoid garlic-flavored and highly spiced foods. These foods can make you uncomfortable or cause heartburn.
- Avoid caffeine late in your watch. Keep in mind, it can take up to eight hours for the stimulating effects of caffeine to wear off.
- Don't drink too much liquid. Drinking lots of fluids before bed can cause you to wake up repeatedly to use the head.
Sleep Disorders
The USCG considers a sleep disorder a "medical condition that requires further review" (see USCG licensing article below). Sleep disorders involve any difficulties related to sleeping, including difficulty falling or staying asleep, falling asleep at inappropriate times, excessive total sleep time, or abnormal behaviors associated with sleep. If any of these problems are occurring, consult with your doctor.
Sleep is a base requirement for quality living. Working and living on a boat can sometimes challenge that idea but with discipline and some simple techniques, we all can get proper rest onboard. |
A Slow Down at the NMC
Recently, we have seen a slow down in the processing of licensing at the National Maritime Center in West Virginia. One mariner applied in January and just now received it, 8 months later.
The majority of the slower processing times comes from the medical division. If you have any type of medical issue, including but not limited to: diabetes, high blood pressure, sleep apnea, poor vision, or are on any prescription medications; the Coast Guard will be asking for a letter from your treating physician. The letter will ask for a complete evaluation of the condition, including prognosis, history of the condition, medications, side effects of medications and some conditions that will require extra testing.
It is recommended that all mariners apply 6 months in advance! If you have any type of medical condition it is recommended that you apply at least 9 months in advance and be prepared to get additional information.
Since you will be applying early, you can avoid a licensing gap by asking the Coast Guard for a Delayed Issuance. With a Delayed Issuance, your license application will be processed. Once approved, the Coast Guard will hold your new license until the month preceding your original expiration date. For example, if you expire in March 10, 2012, you need to apply in September 2011. Your application will be sent to the National Maritime Center. The National Maritime Center will process your security check, physical, sea time, etc. Once all of these are approved they will set it aside. Come February 1, 2012 the Coast Guard will mail your renewed license. It will be dated March 10, 2012 and will be valid five years from the date your old license expires.
If you have any questions regarding the license process or need to renew your license please contact Kelly.

Where Do You Keep Your MMD & TWIC?
Many people keep their TWIC and their MMD (Tankerman ticket) in their wallet. But is this the right place to keep it when you are on your time off?
Several employees who have had their wallet stolen or lost in the last few months may tell you it is not. When you are out shopping or at a social event, you do not need your Tankerman license or your TWIC card. Why not keep it at home? Get a pouch or keep it in a licensing file. Several crew members use zippered pad folios.
This makes one centralized location for all your documents required for work. When you get ready to head back to the boat, place the file in your bags.

Nav Zone: First Hurricane of 2011
This year we have heard little about the 2011 Atlantic Hurricane Season. We are almost three months into hurricane season and are just now seeing one in the Atlantic.
Hurricane Irene is the first hurricane of 2011 Atlantic Hurricane Season. This is the first time since 1851 that the first 8 named storms of the year never developed into a hurricane.
Remember, hurricane season does not end until November 30, 2011. The primary period of hurricane threat is mid-August to mid-October. NOAA updated their hurricane predictions on August 4 to 14 to 19 named storms, 7 to 10 becoming hurricane strength, and 3 to 5 being a Category 3 or higher.
We need to keep a watch on the tropics and ensure we are prepared.
Here are guidelines that must be followed to prepare for a hurricane:
- Secure and clear all nonessential and loose gear.
- Remove all products from drip pans, etc, that can be exposed to weather.
- Mooring lines doubled up with due consideration given to the effects of predicted storm surge.
- Ensure that all personnel are prepared and equipped to safely maintain the vessel during severe weather.
- Wear work-vests when outside.
- Tend mooring lines and have spare lines readily available.
- Have firefighting equipment ready for immediate use.
- Ensure that all side ports, hatches, portholes and other openings are closed and secured.
- Maintain a continuous radio watch and monitor severe weather activity.
- Prior to predicted landfall, plan with scheduling possible safe tie up locations.
- Try to maintain contact with office personnel before, during and after the storm.
- Top off with fuel and water. Get permission from scheduling before doing so.
- After storm passes be vigilant for debris, missing aids, high water and stronger currents.
- Monitor Coast Guard radio broadcasts.
At the your boat's next scheduled safety meeting, discuss the items listed above and other ways to prepare for the potential dangers of Hurricane Season.

Nautical Trivia
On this day one hundred and two years ago, the first concrete was poured in the construction of the Gatun Lock, as part of the Panama Canal. The year was 1909.
It took four years to build all of the Canal's locks. The amount of concrete needed in Panama was of a huge volume - such quantities were not required for any other project until the building of the Hoover Dam, in Nevada, in the 1930s.
 |
Gatun Lock, 1909, re-creation |
After more than 80 years of service, the concrete of the Panama Canal locks and spillways is still, in 2011, near perfect condition. It is a fine testament to the Canal's engineers and builders.
Today, we near the end of the Panama Canal Expansion Project. The project will double the capacity of the Canal by 2014 by allowing more and larger ships to transit.
 |
The official inaugural voyage on the Panama Canal
was made by the "ANCON" in 1914. |
What does it mean for Towboaters? The volume of shipping is expected to dramatically increase in 2014, especially in Houston. The Houston Ship Channel will see volume like never before which means more navigation challenges. |

Answer to this weeks Rules of the Road ....A,D,D,D,B |
I do not know about you, but this summer is the hottest I ever remember. Houston, as of today will hit it's 35th-100 degree day in a row. There have been twenty-one days over 100 degrees. A normal summer in Houston sees four - 100 degree days.
During the early years of the 1980's, I worked much of the time in the Gulf of Alaska and the North Pacific. My normal run was between San Francisco, CA and Valdez, AK. Especially during the winter months, I thought often about the conditions my friends worked under down in the Gulf of Mexico. You know, the balmy days with gentle breezes; brilliant sunsets leading into starry nights.
While they baked in the sun, us Northern sailors fought giant waves and freezing temperatures.
Now though after experiencing a few weeks of 100 degree days, I may have thought differently back then. Looking back, those freezing temperatures may have been welcomed especially if they included some rain!
This heat takes a toll on all of you that work on the water. I am also afraid that the end is not yet in sight. Keep hydrated, work safe and try to stay cool.
Have a great and very safe week!
