 Are You Sick of Motion Sickness? If traveling by car, train, plane, or boat makes you queasy, there’s good news: Not only can you take steps to stop motion sickness before it starts, you may actually be able to conquer it for good. Why some people get motion sickness and others don’t isn’t fully understood. Researchers believe it’s caused by incongruence in our body’s sensory systems. For instance, on a slow-moving cruise ship, your eyes may tell the brain you’re not moving at all, but the systems in your brain and inner ear that control balance and posture (vestibular and somatosensory systems) say, “Yes we are!” This mismatch confuses the brain and causes a variety of symptoms, including: Dizziness Headache Nausea Salivation Sweating Belching Acute awareness of the stomach Vomiting Hyperventilation (in extreme cases) You certainly can take medications to help relieve these symptoms. But if you’d like to try overcoming motion sickness for good, here are so...

 Don't Forget That Engine! Maintenance continues to be the key to a better-running engine and much longer engine life. While there's more to learn than any one article could feature, make these recommended inspections of the following five systems. For expert insight, we checked in with Volvo Penta's service training center supervisor Ed Szilagyi, Mercury MerCruiser dealer service expert Rob Gina of Boatwrench in Longwood, Florida, and other marine pros. Check all of your fluids so as to ensure smooth operation. 1. Fluids Motor oil should be a clean, amber or gold color. Black oil suggests old and dirty oil; change it. In the event that the oil looks milky or foamy, it's contaminated by water-- bring the motor in for service. Check power-trim fluid levels. Inspect trim-pump reservoir caps for the milk-carton-like seal beneath the cap. Dispose of this; it inhibits venting and may lead to leaks. Get rid of the lower gear-case drain screw and check the con...

Don't Underestimate Good Rope Maintenance Raritan Engineering Company your  marine sanitation  experts would like to share with you these topics we thought would be of interest to you this month regarding great ways to keep your ropes clean and in great shape. Your marine sanitation suppliers discusses how if you didn’t remove your running rigging last winter, then there is a good chance you'll be coming back to sheets and halyards coated in dirt, mold, and mildew. • Wash only with a very mild detergent. For relatively new ropes, this means something like Woolite or a half-dose of a modern laundry detergent. For the first few years, ropes still contain thread coatings and lubricants from the factory that provide an easy hand, as well as offer some protection from UV radiation, abrasion, and water absorption. • Avoid contact with acids, bases, and solvents. Both polyester and nylon (polyamide) are vulnerable to certain chemicals, so manufacturers broadly warn again...

  Maintain Your Fuel Tank Don't let this happen to you! November is the time of year when the postponing catches up to people. The huge tasks we avoided all summer stare us in the face. Do absolutely nothing, and you run the risk of a summer lost pulling epoxy from your hair instead of sailing. If your boat is actually 20 years old or even older, a fuel tank replacing-- a bear of a project, even in optimal circumstances-- may be that project you're delaying. If it is, well, you're in luck, since we've got a reasonable bit of information to help guide you through the process. Marine consultant and technical writer Steve D'Antonio wrote an extensive article about tank replacing previously. The following excerpt from that short article deals explicitly with aluminum, however, there certainly are other options. Aluminum is a common substitute fuel tank material choice for most installations. It is simple to work with, easily obtainable, relatively inexpens...
