Pearson Composite’s new Alerion Express 33 runs silently even under power - by EastBayRI.com

A new boat engine constructed by Warren’s Pearson Composites uses a Master volt Lithium-Ion electric saildrive system to navigate the waterways without the use of gasoline.

The motor of the Alerion Express 33 can travel for 15 to 20 miles on a single battery charge, depending on the vessel’s speed, crew numbers, wind and weather, EastBayRI.com reports. Additional battery packs can be added to extend the boat’s range.

Boaters who have tested the vessel reported that the quiet operation and smooth navigation were the most surprising attributes of the Alerion Express.

“I didn’t realize we were under power until I noticed our wake and saw moored boats passing us,” wrote one review, according to the news source. “It took time to adjust my behavior, throttling back when underway.”

Barr Marine Exhaust System Parts

Despite this recent design breakthrough, the vast majority of boats still operate on either diesel or gasoline fuel, and require replacement mechanical parts to maintain proper function.

Internal combustion marine engines contain a marinized exhaust manifold that dispenses exhaust from its cylinders. High velocity exhaust, long-term use and harsh environmental conditions can threaten the life of this part. Barr manufactures replacement manifolds that can be substituted for corroded, failing manifolds.

Even if you don’t own a cutting-edge electric powered boat, you can make you own boat engine operate efficiently and offer a long service life with quality replacement marine parts.

There are two main types of power tilt and trim motors and pumps that are designed for recreational boats that have an outboard or a stern drive.

Older power tilt and trim systems use an electric tilt motor and a mechanical lifting device. On stern drives, the electric motor turns a worm gear and uses a wet clutch pack to tilt the drive unit and lock it into place.

Tilt & Trim Motors and Pumps

More modern boats, such as Johnson, Evinrude, Mercruiser and Volvo Penta stern drives, commonly use an electric / hydraulic power trim and tilt system. This arrangement consists of a 12-volt electric motor with a reservoir and a hydraulic pump or valve body.

Problems with the hydraulic pump or valve body manifest themselves when the trim and tilt motor seems to be functioning properly, but the engine or drive unit won’t stay trimmed, or bleeds when in the upside down position.

In this case, boaters are advised to replace their trim and tilt hydraulic pump and fill the reservoir with the proper power trim and tilt fluid. Captains are cautioned to not use transmission fluid, as the detergents in this solution can wear on the systems’ seals.

Oil coolers with a fresh water cooling system use the water from a lake, river or ocean to lower the temperature of the engine’s coolant. A type of heat exchanger, this product keeps the engine or transmission oil cool while the vessel is in motion.

Mercruiser - Direct Replacement Heat Exchangers & Oil Coolers

Heat exchangers and oil coolers manufactured by Seakamp Engineering are a popular choice for boaters, and can be used for most fluid to fluid cooling applications. Seakamp’s Mercruiser direct replacement heat exchanger allows for freshwater engine cooling as well as the use of a hot water cabin heater when navigating in cooler climates.

In addition, Mercruiser heat exchangers and oil coolers prevent electrolysis by using dual zinc anodes, as well as corrosion resistant metals in their construction. With electrolytic reaction, the zinc will actually corrode and wear away, while preserving the copper and copper / nickel alloy metals that make up in the heat exchanger, oil cooler and engine system.

Heat exchangers and oil coolers are easy to install and can dramatically extend the life of a boat’s engine by protecting the entire motor system from rust and corrosion. Seakamp Engineering products can be customized to the exact requirements, size and fittings of most vessels.

Workers remove containment boom in water contaminated by the BP oil spill, near Chauvin, La. - Eric Gay/AP

At the front line of the BP oil spill containment and clean-up, the primary soldier is the oil containment boom. There is some concern by some US lawmakers and local officials that that the booms aren’t working as intended along the US Gulf Coast.

“There is much more shoreline to protect than lengths of boom to protect it”, says Billy Nungesser, president of Plaquemines Parish, Louisiana. The booms break free and “It washes up on the shore with the oil, and then we have oil in the marsh, and we have an oily boom. So we have two problems.”

Oil containment booms are temporary floating barriers composed of plastic, fabric, and other buoyant materials. They may be held in place with drift anchors and have floats placed along their length to ensure that they are not accidentally broken up and sunk.

The Coast Guard indicates that there are about 3.1 million feet of coastal protection boom available in the US, and about 430,000 feet of heavier-duty boom intended for use in open oceans as is reported to the Christian Science Monitor.

Oil Boom Buoys

Beyond the booms themselves, Taylor Made has come forward with low drag buoys being used in service as oil boom buoys. The primary function of these buoys is to mark the boom. Booms must be tended to make sure they don’t drift away from the spot they are supposed to protect. These oil boom buoys help keep the booms visible and keep a drift anchor afloat.

Canadian Built Tampa Fireboat in Action

A multi-million dollar vessel owned by the Tampa Bay Fire Department in Florida boasted its cutting-edge pumping technology on Wednesday morning, when it put out a major fire at the Port of Tampa.

Early on June 16, several rubber conveyor belts at the port went up in flames, and the Patriot, the new fire boat, came to the rescue, myFox Tampa Bay reports. “With this vessel, the way that it’s built, its set up not only as a fire fight vessel but also as a command and control vessel,” Captain Bill Wade told the news source.

“[The firefighters] can control the situation from their side and make sure that fire crews are acting safely, because fighting a ship is much different than fighting a fire in a building.” Among its features, the Patriot can pump a total of 13,500 gallons of water per minute, which is the equivalent of nine fire trucks.

While recreational boaters don’t need the high magnitude of pumping power required by the fire department, marine pumps nonetheless prove useful to all boat owners. A modern 40’ vessel may have a dozen pumps or more, serving a myriad of functions aboard a modern yacht.

Bilge Pump

An electric bilge pump can remove water that accumulates in a bilge at a rate of about 60 gallons or more per minute. Fuel transfer pumps are typically vane pumps that offer reversible operation. Engine driven pumps can serve for engine cooling, or exhaust cooling. Freshwater pumps can supply water to all the fixtures aboard, transfer water, be used in a bait-well or deck wash-down situation. Finally, macerator pumps and be used to grind waste from a marine toilet, eventually pumping out the slurry mixture when the boat is docked.

Bimini Tops for All Boats

As experienced captains know, the summertime boating season brings abundant opportunities to hit the open water, but can also bring scorching heat. In preparation, local officials of the Emergency Medical Services Authority (EMSA) are advising boaters on Oklahoma’s Keystone Lake to take steps to avoid heat-related illnesses.

“We tend to make it a little more [clear] to our staff with heat related illness treatments [to] make sure we have plenty of ice packs [and] plenty of saline, which is what we provide a dehydrated patient,” EMSA assistant supervisor, Matt Cox, told Fox23.com.

In general, the agency recommends common-sense tips to staying cool, such as finding shade and drinking water, as well as sunscreen and covering up. Jim Crutcher, one Keystone Lake boater, has taken the warnings to heart as he aims to combat the sun. “I wore my sunscreen thick…if you don’t see it it’s not enough,” he told the news source.

Anchorshade II

To keep in the shade while boating, a Bimini top or an Anchorshade II erected over the boats occupants can supply much needed relief. The Anchorshade II by Taylor Made will supply a shade under its 8’ by 8’ single pole umbrella. Because of a fold down frame that supports the Bimini top, it has the advantage that the Bimini can be left up while the boat is underway at speeds below 20 knots. Both the Anchorshade II and the Bimini tops are stabilized with location straps included with each of them. Our Bimini top kits are so complete that all you add is a drill, screwdriver and easy assembly to install one on your boat.

Stay protected from this summer sun this season while boating. A new Bimini or Anchorshade II will provide years of useful service, with quality materials and construction.
