7 Differences Between a Ship and a Boat

This blog is part of a series for new boaters. Boat hulls � the actual bodies of boats � provide flotation and are usually in contact with the water. Boats come in two broad categories: Monohull � Most boats have a single hull with a pointed bow and a flat transom stern. The bottom of a monohull may be flat, round, or V-shaped. Multihull � These boats have two or good boats bad boats and how to tell the difference so hulls joined by a bridge deck or other structure.

Twin-hulled boats are called catamarans, while those with three hulls are trimarans. Boat hulls come in all sorts of different types. Look closely at this hull, below the blue stripes, to find the strakes, which are used to create lift. Photo courtesy Baja Marine Corp. Most people choose traditional monohull designs, although catamarans are becoming increasingly popular for both power and sail.

A boat floats because it displaces a greater weight of water than its own weight. Displacement hull� Some hulls are designed to operate only at displacement speeds. This type of boat is restricted to relatively slow speeds but is extremely efficient to run. Most have a gentle motion while underway, although rolling side-to-side movement can be a problem.

Planing hull� Achieving high speeds on the water requires a hull that easily transitions onto a plane. Characteristics of a planing hull include good boats bad boats and how to tell the difference so bottom surfaces from amidships aft from the middle to the back of the bottom and a flat transom back of the hull. The transom must meet the bottom at a sharp angle.

Absolutely flat bottoms, a sub-species of planing hulls, can be extremely fast but are not easy to control and tend to bull their way through waves like a pile driver. Giving the bow a pointed shape allows a hull to slice through waves instead of slam into. Round bottom � used mostly on boats intended for displacement speeds. This shape provides a gentle efficient ride, but tends to roll from side to side in certain sea conditions.

Low deadrise � Sometimes called shallow-V bottoms, these running surfaces have a deadrise angle of 20 to 25 degrees amidships which reduces to 5 degrees or less at the transom. This provides a smoother ride, but it still retains the quick ability of a flat-bottomed boat to plane. Deep-V bottom � This type of hull has a deadrise of 25 degrees amidships which reduces only slightly to 20 degrees at the transom.

This good boats bad boats and how to tell the difference so allows high-speed operation in rough water. With few exceptions, planing hulls have chines and strakes.

Chines are the angles on the hull where the vertical topsides meet the. They provide lift, which is important in the planing process and overall running efficiency.

Ski boats� Hulls of competition water-ski boats are designed to minimize wakes at certain speeds so that slalom skiers can slice through them more easily. Stepped hulls � Steps are, essentially, elevation breaks in the hull that create multiple running surfaces. As the boat speed increases, it rides on these surfaces, with area Good Boats Bad Boats And How To Tell The Difference Song of contact with the water moving progressively further aft, resulting more speed with less power than a conventional deep-V hull.

The trend in recent years has been toward wider boats because increased beam allows more room for interior accommodations. Wider boats also feel more stable, which makes them popular for dockside entertaining.

A wider boat is more likely to pound slam into waves as it moves through choppy water. Plus, it can take more fuel to move a wide boat at a given good boats bad boats and how to tell the difference so than a narrow hull of similar length. Cruising boats are much wider. The drawback, of course, is more fuel consumption.

Catamarans have become increasingly popular. They are particularly attractive in the fishing market because they blend high-speed performance and a good rough-water ride with a stable platform for angling. Another drawback is less useable interior space than in a monohull of similar length. Each ama is quite narrow compared to its overall length. The narrow amas of a catamaran move easily through the water with minimal power requirements, so high speeds are possible even though the amas might not actually be planing.

Trimarans have three separate hulls. This design has been effectively used by sailboat designers to provide a roomy central hull for accommodations and two outrigger amas for stability.

Instead of three separate hulls, a cathedral design squishes them together until they often share a common planing surface near the transom. Back Explore View All. Back Types View All. Unpowered Boats Kayaks Dinghies.

Of course these rules haven't put all boats on the straight and narrow; some have even gone on to become repeat offenders.

It makes no difference how a boat is damaged � hurricane, striking a submerged object, sinking at the dock, operator error � all are the same when it comes to salvage and wreck removal.

With salvage, your boat is recovered and brought to a repair facility, where insurance pays for the cost of repairs not exceeding the insured value. With wreck removal, the cost of repairs exceeds the policy value and the boat is recovered, possibly in pieces, and disposed of according to local guidelines, generally at a landfill.

Unlike some boat insurers, BoatUS arranges for the salvage or wreck removal. We find the right contractor with the right equipment, barges, transport, and permits, and ensure professional, safe, and timely service.

Fuel-spill liability protects you from claims for cleanup or third-party damage due to the accidental discharge of oil or fuel that can occur in a sinking, fire, collision, or grounding.

This can get expensive quick, depending on the size of the boat and the number of engines that it has on it. Also, what does the rigging look like? If the engine has to be replaced, can you use all of the riggings and stick with the same engine manufacturer? There are a lot of things that need to be looked at in order to determine whether a boat is a good or bad investment. The buy is where we decide whether or not the boat is either of these.

Here is another article that tells you what are the top things you want to look at on a boat or project boat before buying it. Covering all of these bases will keep you from spending your money on a boat that is way overpriced. The last rule of thumb that I would suggest thinking about is; in a pinch can you just turn around and sell the boat for what you paid for it? If a boat is sitting for sale for a long time and no one is buying it.

Then it is either a lot of work or it is way overpriced. When you go to resell it, those that buy and restore boats, pick them up for next to nothing, and they make all their money by doing the work. Next, comes the consideration of what does it actually cost to own the boat? Are you trailering it and keeping it at your house? Do you need to pay for dockage or a storage facility?

Do you have a sufficient vehicle that can pull the boat if you are trailering it? There are a lot of variables when it comes to deciding what it actually costs to own a boat. Every single person is going to have a different situation. These are most of the things that you are going to want to consider for budgeting out what it is going to cost you to own it. If you are looking at a small boat that is on a trailer that your truck can tow easily and you have a great spot next to the garage to keep it safe.

Then your cost there is going to be pretty low. If you are paying for storage, depending on the size of the boat can reach up into the thousands per year. The next cost is maintenance. Maintenance on a boat is everything. This is the life of the engine and the longevity of your investment. The biggest factor here is going to be, can you perform the maintenance yourself, or do you need to pay someone to do this for you?

That is per engine too. Now if you are putting a lot of time and hours on the engine, this cost will go up, the more services you need to perform in a year. There is a huge difference between a real mechanic and the guy that can talk and lead you to believe he can fix your boat.

Boat insurance can range so much depending on the value of the boat. For those estimates, you should get in touch with Boat US, in order to get an accurate price. The depreciation aspect of a boat was touched on a little bit. However, I want to take it just a little further so that you really understand how much it drops. Then tack on the hours on the engines and the value can sink rapidly.

Just knowing that they can depreciate quickly is good, but I also want to put into perspective the financing. Whether a boat is a good investment or a bad investment also comes down to how the boat was purchased.

A boat loan is a lot different than a car loan. You can acquire a boat loan up to even 15 years! Now that is a long time! Depending on the condition. What kind of investment is that? So if you calculate those interest payments over that time period, you will have probably paid double the loan price!

Because they have overpaid, overextended, borrowed too much, and went upside down the day they signed on the dotted line! One of the best ways to make a boat a good investment is to pay for it with cash. That will save you tons of money and keep you from forking over all of that money in interest payments! Now, this is really aimed at those that have the money and with ease make the payments on the loans changing in boats every couple of years.

Those that are not looking at the boat as an investment, but more of an expensive toy that can be written off come tax season. That is different from what we are discussing here today. For those that are in that position, more power too you, have fun on the water and keep on boating!

For the rest of us though, that are looking at this as an investment, a boat can become a money pit with certain attributes. If you never have time to use the boat, and it is just going to be sitting in the sun baking all day every day; then it is going to become a money pit that costs you thousands of dollars every time you go to use it.

The sun will eat up the cushions, the paint will fade, the aluminum will pit, and the engine will begin to have all kinds of problems from sitting and lack of use. It may seem hard to understand, but a boat is made for the water. Water has some serious effects on metal, paints, wood, and especially engines. So as it sits, these things start to pop up. It is going to lose tons of value in the first couple of years.
