Rudder packing glands should never leak and should be periodically checked to ensure they are dry. Any source of water coming into a boats bilge needs to be addressed immediately. It is vitally important that the rudder packing glands (and shaft packing glands) be maintained to the highest standards to ensure your vessel is seaworthy.
As good boating practice, always check to make sure the automatic fire-extinguishing system is ready and operational by ensuring the green helm light turns on when the ignition is keyed to the 'on' position. Whether you have a halon or clean agent system, this is your most critical line of defense when it comes to an onboard fire and should be properly maintained.
In this picture we have a fuel tank inlet that is not properly grounded. The green grounding wire is supposed to be connected from the fuel fill inlet, to the tank, and then to a common ground on the boat, in order to prevent an accidental spark when filling the tank with gas. This could cause an explosion if not repaired. You can see in the picture the ground wire is not connected to anything.
During our pre-purchase yacht inspections we test the air conditioning unit(s) to ensure proper operation, and visually examine the unit providing it is accessible. It's important that the drain pan is properly draining to the sump box or bilge, and that all hoses are double clamped at the seacock, pump and hvac unit, and are not cracked or brittle. A replacement can cost upwards of $4,000.00, and oftentimes if the compressor is bad you will have to buy a whole new unit. At Southern Marine Surveying, we take the extra time to inspect all accessible components of the vessel to give you an unbiased, thorough report of the vessel condition.
The fuel tank vent at the upper right corner does not have a flame arrester screen or splash shield as per ABYC recommendations. On some older boats such as this one, factory hardware was not up to ABYC standards. This particular issue could cause an explosion or allow water to enter the gas tank, which would lead to a whole slew of other problems. In order to remedy this the owner should install a new modern fuel tank vent with splash shield and flame arrester.
A broken deck hatch like this is usually the result of someone stepping on it. A new hatch can cost upwards of 1,000$ and they are important to maintain to prevent water from intruding into the fiberglass or cabin. We always inspect the hatches to ensure they are not cracked or leaking water, and that the struts properly operate. This might seem minor to the average boat owner, until the repair bill comes. Parts like this can be very expensive. Hire a marine surveyor to do a thorough examination of the boat and let you know about issues like this before you buy it.
A cracked fuel hose has the potential to cause a fire or explosion on your vessel. Always ensure fuel lines are USCG approved A1 or A15 type hose and there are no cracks.
This is a plastic thru-hull fitting that is broken. Because of this, water is now coming into the bilge and also absorbing into your fiberglass hull. This can cause de-lamination of fiberglass and could also potentially sink a boat if not repaired.
A burnt shore power connection is indicative of A/C power problems and can cause a fire on your boat. A good majority of boats that burn down are a result of this.
This is a Huge red flag. The locking rings on your shore power connection should be used as intended, and never broken. A loose connection as pictured, can cause a fire.
Wire nuts might be ok on an automobile, but Never on a boat! Wire connections should always be sealed from moisture with heat-shrink connections and protected from vibration by using quality butt connectors.
Usually Galvanic corrosion is a result of bad anodes or excessive salt-water use without proper care. In this case, the entire lower unit had to be replaced.
A torn exhaust bellow on an inboard/outboard motor. By hiring us to look at it before you buy it, you not only save yourself potential money in repair costs, but you protect yourself and your family by ensuring your boat is seaworthy and safe.
A leaking dripless packing gland has the potential to sink your boat if not repaired. Old style shaft packings are designed to drip a small amount, but dripless packings should never leak. Periodically visually check your packing glands to ensure they are not leaking (if they are dripless style). Boat Inspector in Dallas
By not addressing a faulty sump-box you are assured to have future problems. On this boat water leaked into the bilge and left a nasty rust colored water line (and foul smell). The bilge should always be kept dry and clean.
The fuel system is one of the most critical parts of your boat and must be maintained to the highest standards.We meticulously check all parts of the fuel system to make sure the boat is safe for operation.
A Leaking fuel tank is a huge cause for concern. Not only can it cause a fire, often-times it's not accessible and/or very expensive to replace. Sometimes even necessitating cutting into the side of the boat to remove. By hiring a marine surveyor we ensure the tank is in good condition with no leaks.
A Gelcoat gouge like this can often be hard to spot. Not only are they expensive to fix, but water is now absorbing into the fiberglass which can result in future problems. A marine surveyor has a trained eye to spot gouges like this.
Engine compartment blowers are criticaly to the safe operation of your vessel. Without a properly operating blower you risk having an explosion on your boat. Ensuring the blowers are operational, properly routed and hoses intact as per ABYC standards, is one of our most important priorities.
A damaged exhaust manifold like this could ruin your engine by allowing water into the cylinders. Oftentimes this is caused by old age and or neglect such as not winterizing a vessel. It's important your exhaust manifolds are in good condition to avoid water ingestion. We do our best to determine the condition of the manifold but recommend hiring a certified mechanic if any doubt exists.
Oftentimes the thru hull will look intact and operational from the outside of the vessel, but on closer examination the hose connected to the thru hull will be cracked or broken like this on the inside, thus allowing water to spill into the bilge. This needs to be addressed and is an important priority to avoid taking on water and potentially sinking a vessel.
Properly maintained batteries are critical to the safe operation of your vessel. A battery explosion caused by old age or neglect can wreak havoc on your engine compartment and has the potential to cause a fire. We examine the battery's, ensuring they are in good condition and are maintained by ABYC standards.
Damage like this is caused from not lowering your outboard motor all the way down during cold winter months. The accumulated water can't escape, freezes and thus causes the cracks you see here in the lower unit housing. Be sure to always have your outboard motor trimmed all the way down during cold winter months.
Osmotic blistering like this is very common on North Texas yachts due to the water temperature fluctuation in our lakes. This should be fixed to avoid future repairs and costly problems. During the out of water inspection we are sure to find all and any blisters on your vessel so that you can be well informed and aware of the problem.
Properly functioning anodes are important because they keep your boat safe from corrosion/electrolysis. We check all anodes to ensure they are in good working condition.
The damage you see here was caused by not winterizing this engine. The exhaust manifold is cracked from water unable to escape, freezing, expanding and eventually cracking the manifold. Be sure to always winterize your engine!
During the out of water inspection we always check prop shafts to make sure they are straight and in good condition. A bent prop shaft can be a costly repair, and is often indicative of a grounding, which is indicative of other problems.
Checking the oil is one of the first things we do when inspecting an engine on your vessel. A milky colored oil like this is indicative of serious problems (water ingestion) and is often a "deal breaker" when it comes to buying the vessel.
This is a very seriously damaged prop! Often times though, the damage is not as obvious as this. Even a very slight bend or contusion on the prop can cause a noticable vibration when operating your vessel. It's important to make sure your prop is in good condition with no nicks or bends. We meticulously check the props during the out of water inspection to ensure they are in good operational condition.
Gelctoat stress cracks are common, and nothing to be alarmed about unless they are very numerous. However, from a cosmetic standpoint they can be an eyesore, and they are expensive to fix properly. During our survey we note any and all stress cracks so that you can be informed during the purchasing process.
Gelcoat crazing on the transom of a 41' Searay. This was caused by UV damage over an extensive amount of time. It's important to keep your vessel waxed to prevent this kind of gelcoat damage, especially in areas that receive the most sunlight. While superficial, it can be very expensive to repair.
Milky colored oil from a boat surveyed. This indicates water ingestion and is a major cause for alarm. It's possible this could result in thousands of dollars to repair. Hire us to find things like this before you buy that boat!
Trim cylinder anode(s) on an out-drive. This most Definitely need to be replaced. We recommend our customers to be sure and replace anodes when they periodically service their out-drives, to prevent corrosion and extend the life of their machinery.
In accordance with ABYC recommendations all fuel lines should be double clamped where possible. It's important to ensure all fuel lines are secure and properly clamped to avoid fuel spills and possibly a fire or explosion on-board your vessel. It's equally important to ensure all raw-water hoses onboard your vessel are clamped and double clamped where possible.
A faulty raw water hose could sink your boat.It's of the utmost importance to maintain all raw water lines to avoid problems and ensure your safety while out on the water. Cracked, brittle and old raw water hose's need to be replaced.
Gel-coat void found on a 2013 cobalt. While this is minor, it pays to hire a surveyor to find things like this before you buy a boat.
The bottom inspection is one of the most critical parts of a pre-purchase boat survey. Spotting blisters like the ones sighted below, and repairing them before they become a serious problem is important to properly maintain the hull of your vessel.
An improperly sealed port-hole could lead to water intrusion and result in stains, mildew and possible structural damage from long term exposure. It's important to ensure your portholes and windows on your boat are properly sealed to prevent leaks and provide optimum protection from outdoor elements.
Torn blower hose on a 2006 Chaparral. Properly operating blowers are essential to keeping you and your passengers safe from gasoline fume generated explosions. Always use your blowers when filling up your gas tank and when operating the engines.
During the out of water inspection we always check the cutlass bearing(s) to ensure it is in proper working condition. Oftentimes a bad cutlass bearing will produce vibrations at various rpm's and eventually could cause damage if not addressed.
Rotton wood behind a headliner on a 1987 340 Searay. This was most likely caused from a water leak resulting from an improperly sealed hardware item on the deck above it.
We always test trim tabs to ensure proper operation, visually check the reservoir for proper fluid level, and look at the cylinders to ensure there are no leaks.
It's important to make sure the zinc anodes on your hull, out-drives, shafts, rudders (etc, etc), are in good operational condition to avoid severe galvanic corrosion like the above picture. We always check the zinc anodes on our surveys to ensure your boat is properly equipped to prevent corrosion.
For pre-purchase surveys it's critical to not only visually check and start the generator, but to test it while it is on a "load" to ensure it will properly operate when using onboard accessories.
We inspect each speaker, remote, amplifier and head-unit to ensure proper operation.
Bottom paint is critical if you plan on keeping your vessel in the water. Knowing the condition of the paint before you purchase a vessel is important to keep you from future problems and as a bargaining chip while negotiating a price.
Leaving teak un-protected like this can lead to degradation over time. It's important to keep your teak either varnished or oiled to prevent uv damage from prolonged sun exposure.
We take the time to go through your vessels battery components to ensure proper operation, safety, and to educate you on the proper operation of battery switches and components.
Proper Out-Drive maintenance is crucial to avoid costly repairs and smooth operation. In this picture, the lower unit is moderately corroded and will need to be sanded down and re-coated, along with a new set of anodes to prevent future corrosion and premature failure. This was more than likely caused by not replacing the anodes sooner, and allowing the out-drive to sit in the water un-protected for a lengthy amount of time.
Cold weather and freezing temperatures can sink your boat if you do not winterize it properly or prepare for the change in temperature. It is important to always close seacocks and through-hull fittings, as well as keeping the ambient temperature above freezing in the engine compartment of your vessel by using a bilge heater. Often times, as was the case in the above picture, people leave seacock valves open, water inside the hose freezes and contracts, and the hose lifts off the through hull barb, allowing water to pour into your vessel. If your boat has strainers installed to filter raw water, it is especially vulnerable in freezing temperatures as the water can crack and break the sight glass on your strainer, causing an uncontrolled influx of water, and sinking your boat. Don't be That guy (or gal)!
As I was speaking to a customer the other day, he asked me why I emphasise so much the importance of maintaining a vessels seacock/through-hull valves. Well here is why. That seacock valve is the only thing keeping water from coming into your boat should a hose fail. In such an emergency it is Critical that you are able to close the valve thus stopping the flow of water into your bilge. A bilge pump will Not always save you and should be considered a last ditch safety mechanism. Also, if a through hull is not properly bedded it can cause water seepage/leekage which could lead to hull delamination among other things. So That is why I spend so much time inspecting every vessel through-hull seacock. In my mind there are few things more important on a boat.
When battery terminals are allowed to get corroded they cannot operate efficiently and will often times exhibit reduced power output. It is important to keep your battery terminals clean and free of corrosion.
Having a galvanic isolator installed on your vessel will help to preserve your zinc anodes and reduce the amount of corrosion being incurred on your underwater machinery by preventing stray D/C current coming into your shore power ground wire while at a marina. At most populated marinas, boats that are moored act as one giant battery since they are all connected by the shore power ground wire. A Galvanic Isolator prevents the stray dc current from coming onto the vessel, thus reducing and preventing corrosion caused by this problem. However, even with a Galvanic Isolator it is still Crucial to continually monitor and replace zinc anodes when they are no longer serviceable.
This damaged prop was knocking against the rudder making a loud banging sound with every revolution of the blade. However, sometimes a damaged prop will not give off any tell tale signs of damage. This is especially dangerous because even if you cannot feel a vibration or noticeable indicators, the damaged propeller is still causing a harmonic/vibration that can cause damage to machinery (such as shaft bearings) with continued use.
A gelcoat gouge with exposed fiberglass as in the picture, is mostly harmless if it has not ruptured the hull and is above the water line. However it is important to prevent moisture from saturating into the fiberglass, so if the gouge is below the water line it is especially important to repair it.
Raw-water strainers are susceptible to leaking and need to periodically be checked. They are especially vulnerable when temperatures dip to below freezing allowing the water inside to freeze, expand and rupture the glass. It's always important to periodically check your strainers to ensure they are not leaking and securely bolted down.
A leaking fresh water pump is often the culprit when water is spotted in the bilge or inside a cabin space. Make sure the connections are thoroughly snugged onto the barbs with hose clamps to prevent leaks. Sometimes with age the actual pump housing can also leak, in which case replacement is necessary.
Batteries should always be installed in a ventilated space and never in a cabin area unless it is a sealed gel type battery. In this picture we have a battery installed beneath a bed storage space inside an enclosed cabin for a tunnel thruster. This battery is a wet cell battery and is Not installed in a ventilated compartment as per ABYC recommendations. Also, it does not have boots installed on the connections which is also against ABYC recommendations. This needs to be replaced with a sealed gel type battery or have a means of ventilating the space installed. When traditional wet cell battery's charge they can emit toxic fumes that can cause an explosion or poison occupants. This is why it's import to always ventilate battery compartments.
Shower sump box's often get neglected because many owners don't even know they exist. If the pump inside the box is broken or clogged, condensation from your A/C unit and water from the shower cannot be drained properly. Usually what happens is the box will overflow, spilling soap scum and nasty water into your bilge where it will sit and stagnate. This can not only produce an unpleasant smell but also standing water can cause fiberglass and wood rot if left unattended. It's important to check on your sump periodically to ensure it is working properly.
Without a properly operating automatic float switch your bilge pump does not know when to turn on. It is imperative that the float switch is operating correctly in order for the bilge pump to effectively remove water from the bilge. During our pre-purchase surveys we always ensure proper operation of the bilge pumps.
