Kids Learn Hands-on Science at Kentmorr – Raise Oysters to Help the Chesapeake Bay

Students from Dunloggin Middle School have been raising baby oysters (called oyster spat) in cages at the marina for the past 6 years. In that time frame, the students have raised and relocated nearly 50,000 oysters to a sanctuary reef at the mouth of the Severn River. These budding young scientists who have an interest in marine biology or environmental science help provide care for the oyster spat that are housed in 20 cages located on the docks of the marina. In addition to the large group data collections that occur in the fall and spring, the students and their families are also required to visit the marina at least 1 other time throughout the year to provide care for the oysters, take water quality readings, record observations, and then share the data with other members of the group through a Google document. At the end of the year, the students take a field trip to the Chesapeake Bay Foundation where they relocate their cultivated oysters. The students work closely with several groups including the Chesapeake Bay Foundation, Oyster Recovery Partnership, the UMCES- Horn Point Oyster Hatchery, Clearshark H2O, and the Coastal Conservation Association of Maryland.

The trip they took earlier this fall was a professional learning activity they designed for the faculty at Dunloggin Middle School. Daniel Blue, science teacher at Dunloggin Middle School, and another teacher co-wrote and received a grant from the Chesapeake Bay Trust so that they could show the staff exactly what their students do throughout the year as there are many cross curricular tie-ins to the study of oysters and oyster harvesting in the Chesapeake Bay. All in all, it was a very fun day and the staff really enjoyed themselves.

Kentmorr Marina management is pleased to be able to host the Dunloggin Middle School students and foster their learning about the Chesapeake Bay and its native species.

How to Winterize Your Boat - 10 Tips

It’s always sad day when you have to start preparing to winterize your boat. As you enjoy the season’s final weeks of sea and sunshine, get a jump on the process and take care of as many things you can do early in the Fall. If you start early, it won’t be a made rush at the first hard freeze when you might forget a critical step, and your boat will be easier to get launched in the Spring.

Whether your boat has an outboard, gas inboard or stern drive engine, the following nine steps will assure quick, easy startups when the snow melts and warm weather returns come spring.


Moisture and acids in old oil will pit bearings and other engine parts while in storage, so you need to drain it. First warm up the engine, while in water, so more of the dirty oil will drain out and impurities will flush out more easily.

Then use high-quality oil and filters as recommended by your engine’s manufacturer. For 4-stroke outboard motors, change the oil and filter before storing for the winter.


To prevent damage from expanding water when it freezes, you must drain water from your engine.

For inboard and sterndrive engines: Flush the engine with clean water by using water muffs or a similar device to connect a garden hose to your cooling system. (Never run a water engine without water). Then flush until the engine reaches normal operating temperature.

Next, remove drain plugs. These are usually located in the engine block and manifold. You may also need to remove the water pump hose to drain remaining water.

For outboard engine maintenance: First, make sure all drain holes are open. Then start the engine and clean the cooling system by flushing it with fresh water. (Use water muffs or a similar device connected to a garden hose.) Flush for a few minutes.


Fuel can deteriorate in as little as 60 days, causing gum and varnish to build up in your engine. This results in hard starting, poor performance and reduced engine life.

The easiest way to prevent these problems is by adding a high-quality marine fuel stabilizer to prevent fuel deterioration.

Then fill the tank with fresh fuel to prevent corrosion-causing water condensation. Simply run the engine for a few minutes to get treated gas throughout the system—either when your boat’s in the water or while using a fitting designed to run the engine with a garden hose.

Note that draining gasoline does not prevent varnish formation in engines since some fuel is always left behind. In addition, gaskets can dry out and cause leaks in the spring.


While in storage, engine oil drains away. This exposes internal engine components to harsh elements in winter and can lead to corrosion and metal-to-metal contact, called cylinder scuffing, come spring.

To prevent these issues, use a fogging oil spray. This type of product is specially formulated to penetrate deep into the engine and coat parts with a protective layer of anti-corrosive compound.


Drain the lower unit of old gear oil and replace with a fresh supply. When changing the gear oil, be sure to check for moisture. If water comes out first, or if you see milky or lumpy oil, this is an indication your boat is experiencing moisture contamination and will need new seals before next season.


Find your engine’s grease fittings (most will be located in the steering mechanism area), then use a quality marine lubricant to protect against rust, corrosion and oxidation. Check your owner’s manual to be sure you don’t miss any important areas that need to be greased before winter storage.


Boatyards receive little traffic in the winter, which makes break-ins easy. Remove all valuables, including expensive electronics. It is also in your best interest to insure your boat, even when it’s not on the water.


For smaller boats, pull your battery, inspect it, clean the terminals if necessary and store it in a dry place and connect it to a trickle charge over the winter. For larger boats in a yacht yard, make sure you have a solid power supply for charging over the winter.


Protect gelcoat and other surfaces from harsh winter weather with a good cleaning and waxing before covering for the winter. It will make launching your boat more easily in the Spring when you are anxious to get it back in the water.


The best place to store your boat is in dry storage, but this can be expensive—especially in areas with long winters. At a minimum, you’ll need to cover your boat with a durable cover. Another good option is to shrink wrap your boat.

If you do shrink wrap your boat, make sure the boat is well-ventilated. Air circulation prevents mold and mildew from forming down below and keeps the boat smelling fresh. Treat any mold that you find now before it gets worse.
