Eye on Design: Repair and Conversion Conundrums in Hybrid Propulsion

I recently built a 35 foot Solar Hybrid Electric Wheelchair Accessible Catamaran for my wife who became wheelchair bound a few years ago. (In typing this sentence, I just realized that this vessel can be referred to as a SHEWAC)It is only a 35 foot recreational vessel, but it contains all the propulsion pieces that are found in any other modern hybrid propelled vessel.I have operated the vessel for one summer and have learned a lot of things that I had not considered when I first conceived her.Fortunately…

Maritime to Get Biggest Bang for VW Settlement Bucks

Imagine a settlement over falsifying emission levels in another transportation sector dropping money onto your deck. Who knew? But it’s true. The $2.9 billion settlement fund Volkswagen agreed to capitalize for distribution across all 50 states, tribal lands and Puerto Rico, as a result of “dieselgate,” its criminal dodging of required auto emission levels, presents an unparalleled opportunity to maritime companies that want to move their noxious diesel engines up a couple of EPA notches, and stick someone else with close to half the bill or more.

Fiberglass Exhaust Tube Offer Lasting Durability

For maximum horsepower, vessel owners and builders optimize every aspect of their exhaust systems. Exhaust systems manufacturer Marine Exhaust Systems says its fiberglass tubing provides the gas flow that these vessels need to excel on the water. Each section of tubing is engineered using multiple layers of hand-laid, biaxial strand fiberglass and encapsulated with an epoxy vinylester resin in a 60:40 ratio. This proportion makes Marine Exhaust Systems' tubes resilient with a strong elasticity and shatter-resistant.

Why Should I Care About Thermal Insulation?

There are a million important things to worry about on any vessel, so why does high-performance thermal insulation deserve a place on the list? Answer: Because it has a very important role to play in keeping your vessel out on the water, being operated safely by a crew and safely carrying passengers. What is High-performance Thermal Insulation? When we talk about high-performance thermal insulation, we’re talking about insulation that can stop a significant amount of heat, in a relatively small space.

New Muffler Cools Water Inside

Marine Exhaust Systems introduces its new Thinline Linear Muffler with a throughport raw water bypass. The new, patent-pending design handles excess engine cooling water inside the muffler, and avoids the pitfalls of aging and often inaccessible connections and clamps. Building on its Thinline series, the company has built a bypass cavity into the muffler to handle the water that is not required for exhaust cooling. There is no impact on the unit's performance. Instead of having one baffle in the muffler…

Compact Genset Muffler Fits Tight Spaces

Fitting a generator and its exhaust system into a new build or a retrofit can be challenging, especially in a confined engine room. Marine Exhaust Systems said it aims to solve the space problem with its new whisper-quiet Series 4 Thinline Wall Pack Generator Muffler. Currently designed for up to 35 kilowatt gensets, the muffler is 12 inches wide, 17 inches tall and four inches deep. Its compact, low-profile size makes it suitable for any marine application, and it can be mounted on the hull side, a bulkhead or within the recess of a generator body.
