Raritan Engineering Vacuflush Specialists Share How to Make Lake Water Drinkable

Raritan's Vacuflush Distributors Offer Free Lake Water Cleaning Tips

Raritan Engineeringyour Vacuflush suppliers would like to share with you this week information regarding how to make lake water drinkable.

Reader David Brezina, who sails a Tartan Ten out of Montrose Harbor, Chicago recently had a question forPractical Sailorregarding drinking water. Like many Great Lake sailors who race seriously, or who own boats that were once raced, his boat has had its permanent water tank removed. After all, when you sail on a virtually limitless supply of drinking water why bother with a water tank?

Brezina wondered if the General Ecology QC2 filter we reviewed in August (see Effective, Affordable Water Filters,PSOctober 2013) would be enough to make the lake water safe for drinking.

The short answer is probably, but to be safe we'd take a couple extra steps. Theoretically, a filter that meets theNational Sanitation Foundation(NSF) P231 standards will be sufficient to make Lake Michigan drinkable (see Making Sense of Water Filter Certification,PSAugust 2016). A more effective (but more expensive) choice would be to use a filter that meets the more stringent NSF 53 standard. Although the General Ecology filter that you are referring to is not certified to either standard, the maker has had it independently tested over the yearsto ensure it meets or exceeds NSF 53. Many Great Lake sailors use manual or battery-operated water purifiers that campers and hikers use in the back country. These products, typically certified to P231, are usually low-volume systems like the Steri-pen (See SteriPEN Portable UV Water Purifier, September 2008).

Your Vacuflush Suppliers Give Answers to the Concerns You Might Have Toward Drinking Lake Water

Your Vacuflushmanufacturers discuss how although these portable systems have proven effective in making lake and river water safe for drinking, a cost-effective way to be even more certain that your drinking water meets safe drinking water standards is to follow the three-step process that we outlined in our series on treating onboard drinking water.

First, you need to prefilter the water to remove dirt before it goes into the tank. The 1-micron Baja Filter that we wrote about in 2015 is a favorite tool for this, but we looked at various other filters that will prevent solids from getting into the tank (see Water Tank Filters, PS June 2015). Clean water is required for the next essential step, chlorine treatment.

Chlorine treatment will kill viruses and bacteria. Although regu lar liquid chlorine will work, it isn't ideal for storing aboard. We found pool and spa chlorination tabs to be a convenient alternative for chlorinating tank waters (see Keeping Water Clean and Fresh, PS July 2015).

Although this multistep step process might seem like overkill, it is very similar to that used by municipalities that draw their water from the Great Lakes. It is still possible that naturally occurring algae blooms can introduce toxins that these steps won't catch, but this is very unlikely.

Fortunately most areas of the Great Lakes remain relatively pristine and are a safe sources of drinking water that is easilytreated on board a sailboat.

Macerating Toilet Professionals Talk About the Secret to Flotation Science

Your Macerating Toilet Specialists Further Discuss Cool Ways to Get Your Kids to Love Boating

Raritan Engineering your macerating toiletdistributors would like to share with you these topics we thought would be of interest to you this month regarding the secret to flotation science.

In order for ships to journey across the open sea, they must withstand the tremendousburden, or weight of the ship, along with the crew,luggage, supplies and passengers. Your macerating toilet suppliers talk about how they do that with a little help from the principles of density and buoyancy.

That's why when engineers ta lk about how heavy a ship is, you'll hear them talk aboutdisplacementinstead of weight. To keep from sinking, the cruise ship has to displace its weight in water before it's submerged. That's a lot easier to do if the cruise ship is constructed in a way so that it's less dense than the water below it.

Engineers help ships to achieve buoyancy by choosing lightweight, sturdy materials and dispersing the weight of the ship across the hull. Thehull, or body of the ship below the main deck, is typically very wide and has a deepbase line, or bottom.

A round-bottom displacement hull looks like a large rectangle with rounded edges to dissipatedrag, or the force exerted against a moving object. The rounded edges minimize the force of the water against the hull, allowing large, heavy ships to move smoothly along.

Find your marine toilet of choice at Raritan Engineering, where you can always take care of your marine sanitation supply needs.

Like just about everything in our lives, round-bottom displacement hulls have advantages and disadvantages. Unlike a boat with a v-hull, which rises out of the water and skirts the waves, round-bottom hulls move through the water, making them extremely stable and seaworthy.

The hull serves not only as stability but also as protection. Reefs, sandbars andicebergscan tear apart fiberglass, composite materials and evensteel.

Now that we've learned how these massive ships float, let's look at the various propulsion systems that propel them from port to port.

The science behind floating was first studied by anancient GreekscientistnamedArchimedes. He figured out t ha t when an object is placed in water, it pushes enough water out of the way to make room for itself. This is calleddisplacement.

Have you ever experienceddisplacement? Of course, you have! Remember the last time you got into the bathtub and the water level went up? That'sdisplacement. When you got into the tub, water got out of your way to make room for you, so the water level in the tub got higher.

An object willfloatif the gravitational (downward) force is less than thebuoyancy(upward) force. So, in other words, an object willfloatif it weighs less than the amount of water it displaces.

Ahuge boat, on the other hand, willfloatbecause, even though it weighs a lot, it displaces a huge amount of water that weighs even more. Plus, boats aredesignedspecificallyso that they will displace enough water to assure that they'llfloateasily.

Boat Head Experts at Raritan Share the Pros and Cons of Joystick Piloting Systems

RaritanBoat Head SuppliersGive Info to Help You In Your Navigational System Purchase

Raritan Engineering you boat headdistributors would like to share with you these topics we thought would be of interest to you this month regarding the pros and cons of joystick piloting systems.

Evinrude's new iDock joystick docking system is designed to give experienced and first-time boaters confidence at the dock.

Your boat head manufacturers talk about how that was the goal of Evinrude Outboard Motors, a division of Bombardier Recreational Products, as the company said today that it is introducing the Evinrude iDock joyst ick piloting system.

Your marine products for sale experts share how the intuitive, integrated system will be available this fall for boaters who own or purchase twin Evinrude E-TEC G2 150-hp to 300-hp engines.

In addition to providing experienced captains and first-time boaters alike with 360 degrees of confidence when docking or maneuvering in close quarters, Evinrude has ensured its latest technology is accessible for all components of the system, from the joystick to the rigging.

We made the iDock system intuitive, using gyroscope sensors to help hold the heading of the boat, which corrects for wind and current automatically, said Jason Eckman, global product manager for Evinrude. It really gives the boat operator complete control at his or her fingertips.

In case you need additional thrust, you put a little more pressure on the joystick, and it moves into the boost position to give you the additional thrust you need, up to double, if necessary, he said.

Your marine supplies near me professionals talks about how a gentle push of the joystick, and each outboard motor will automatically and independently adjust accordingly to ensure that the hull is moving in the direction and at the speed the operator desires.

Eckman said Evinrude engineers began with the goal of creating easy-to-use technology that would also be easy to own. It resulted in a simplistic design feature, which means clutter-free rigging.

Installation time is minimized, which helps keep costs down. The iDock models follow the same installation process as the Evinrude E-TEC G2 models, requiring less than an hour of on-the-water setup.

< p>Eckman said that all helps make iDock more attainable.

We know in our industry that docking is an anxiety that almost all boaters have, he said. As boaters, we're spending a lot of money and we take a lot of pride in what we own, but nobody wants to look dumb at the dock.

Your marine supplies Jacksonville, FL suppliers discuss how our test run was a short preview. Mercury will officially launch the joystick piloting system for outboards in February 2013 at the Miami Boat Show.

Macerator Toilet Distributors Discuss the Importance of Using Caution When Buying a Storm Damaged Boat

Raritan'sMacerator Toilet Specialists Give Tips to Consider Before Buying a Storm Damaged Boat

Raritan Engineeringyour macerator toilet suppliers would like to share with you this week information regarding the importance of using caution when buying a storm damaged boat.

If you are in the market for a used boat and live where winter storage is the norm, now is probably one of the best times to bargain. The owner is looking at another year of storage bills for a boat he no longer wants, and he knows that trying to sell a boat that's buttoned down for the winter is like trying to sell a house that's under a circus tent.

However, if you are anywhere near the pathway of last year's Hurricane Matthew, that barg ain boat might well turn out to be your worst nightmare. Back in 2007, we published aspecial reporton what happens when a fiberglass boat is subjected to the point loads that can occur during a storm.

One recurring theme in the threePractical Sailorarticles I cite above is that severe structural issues can quickly turn a bargain boat into bottomless moneypit. Here are just three of the serious problems to look for.

Macerator Toilet Experts at Raritan Engineering Share the Secrets to Finding the Right Deal on Your Next Boat

Core damage Your macerator toiletexperts talk about how once the outer skin of a cored hull or deck is breached, the core damage can spread widely. Most often, this is a long-term process as plywood or balsa (probably the most common core material in production sailboats) rots. A Matthew boat that has suffered a breache d hull or deck might have damage limited to a small area that might be relatively easy to address.

Secondary bond failure The chemical bonds between interior structures (such as bulkheads, pans and liners, and furniture) are generally not as strong as bonds formed during the molding process.

Hidden structural failure Mast, keel, and rudder loads spread throughout the boat's hull. This means that a simple grounding can cause damage in places far away from the point of impact. It is not uncommon that a boat that has grounded hard shows structural failures in unexpected areas of the deck, main bulkhead, or mast partners.

Submerged engine Beyond the obvious problems such as water-stained woodwork, ruined upholstery, and mold and mildew, there are less obvious problems associated with a boat that has sunk. A diesel engine that has been damaged by salt water can often be resurrected to run temporarily without addressi n g corrosion issues that can come back to haunt a new owner.

We strongly encourage anyone contemplating buying a storm-damaged boat to work closely with an experienced surveyor. Taking on the challenge of restoring an insurance write-off is not for the faint of heart, and in many cases, does not make economic sense.

Macerator Pump Experts Share Holiday Boating Safety Suggestions

RaritanMacerator Pump Specialists Give Ideas On How to Keep Your Family Safe During the Holidays

Raritan Engineering your macerator pumpsuppliers would like to share with you these topics we thought would be of interest to you this month regarding holiday boating safety tips.

Your macerator pump professionals share how three percent of BoatUS members who responded to a recent survey said fireworks displays are the only reason they will venture out after d ark all year long.

BoatUS said the Fourth of July holiday period is shaping up to be the busiest time of the year for the nations recreational boaters, with boating traffic potentially surpassing last years levels.

The BoatUS member survey also showed that about one in three, or 36 percent, of respondents are very to extremely likely to operate a boat at night to see a Fourth of July fireworks display from the water.

Three percent said fireworks displays are the only reason they will venture out after dark all year long.

With nearly 12 million registered boats on the water, boaters will need to take special safety precautions during the holiday period,BoatUS Foundation for Boating Safety and Clean Water president Chris Edmonston said in a statement.

Browse our macerator pumpselection here at Raritan Engineering where we always take care of your marine sanitation supply n eeds.

BoatUS is offering eight tips to boaters on the holiday wait to celebrate with alcohol; the more lookouts, the better; go slow after fireworks; get kids life jackets free via the BoatUS Foundations free kids life jacket loaner program; dont overload the boat; be a safe paddler; and urge people to never swim near a dock with electricity or in a marina or yacht club.

Lastly, BoatUS urged boaters to avoid the two biggest hassles.

The nationwide TowBoatUS on-water towing fleet traditionally reports hundreds of battery jumps and anchor-line disentanglements over the holiday, the group said.

The U.S. Coast Guard Auxiliary is urging all boaters to use extra caution while boating during the upcoming July 4th holiday. The 4th of July, along with Memorial Day and Labor Day, typically account for more than one third of all boating related accidents and fatalities.

In light of the dangers, the Coast Guard Auxiliary is offering seven tips to stay safe while b oating during this busy summer holiday:

• Always wear a life jacket: While in many areas of the country its hot and steamy, dont be tempted to forgo wearing a life jacket. Accidents happen quickly, and often there isnt time to put on a life jacket once an accident has happened.
• Make sure your boat is properly equipped and that required equipment is functioning properly: The 4th of July is sometimes the first and only time people venture out on the water after dark.
• Be prepared for emergencies: Accidents happen quickly, often with little or no warning. Take the time to familiarize your crew with basic emergency procedures, and show them how to contact authorities for help via marine radio or cell phone.
• Boating and alcohol do not mix: Boaters are also reminded of the dangers of drinking and boating. Along with decreasing the operators ability to make good judgments, the consumption of alcohol also negatively affects the ability of passengers to resp on d in the case of an emergency on the water.
• File a Float Plan with a friend: A float plan for a boater is similar to a flight plan for a pilot. It lists who is going, where youre going, what the boat looks like, and when you expect to be back.
• Practice the 3 Cs caution, courtesy, and common sense: Use caution, especially in close quarter maneuvering situations with other boats. In such situations, slow speeds are better.

By following these seven simple tips, you could save your life or the life of your passengers.
