Boat dry weights.<\/strong><\/p>\n

Because they want to avoid a bad comparison with a competing manufacturer who publishes it (dry weight) since the data is rather favorable.<\/p>\n

Why? <\/strong><\/p>\n

Because they want to avoid a bad comparison with a competing manufacturer who publishes it (dry weight) since the data is rather favorable.<\/p>\n

\"<\/a><\/p>\n

\u00a0<\/strong><\/p>\n

Is it important to know\u2026 <\/strong><\/p>\n

\u00a0<\/strong>Yes, of course, it\u2019s very important. Dry weight gives a very good idea of the quality of the construction, the quality of the structure, which translates into greater comfort in rougher waters.<\/p>\n

The empty weight excludes all liquid tanks and, of course, all possible options such as rigid roofs. The empty weight is the weight of the boat for the basic model without options.<\/p>\n

To those who will tell you that the boat is light because of the use of carbon fiber or Kevlar, yes, it\u2019s true, but check your claims before concluding. Some mention carbon fiber or Kevlar, but if this is the case, it must be explicitly stated by the manufacturer. Some manufacturers use carbon for the out-of-water parts, such as the rigid roofs, and the mast for the radar, to reduce weight and achieve a better center of gravity, for example.<\/p>\n

More on this subject later in this text<\/p>\n

It\u2019s the fluids that increase the weight of a boat, and of course the hardtop and certain other systems.<\/p>\n

Nowadays, manufacturers sometimes indicate LIGHT WEIGHT or nothing at all, so we have to conclude that it\u2019s most likely with fairly significant levels of liquids for LIGHT WEIGHT, or the maximum weight with all liquids and options in the situation where you only see the DISPLACEMENT mention.<\/p>\n

What you need to know\u2026<\/strong><\/p>\n

1 liter of water weighs 1 kg and oil is slightly lighter than water, but this is negligible.<\/p>\n

So 1 kg = 2.2 lbs.<\/p>\n

1 us gal = 8.4 lbs<\/p>\n

So a boat with a 600 US gal. fuel tank plus a 200 US gal. drinking water tank adds more than 6700 lbs in pounds to the weight of the boat with full tanks.<\/p>\n

It\u2019s difficult to verify other weights, such as a hardtop on a 60-foot yacht, the presence or absence of a crane or hydraulic system, the addition of teak everywhere\u2026<\/p>\n

There\u2019s also the addition of a Seakeeper in the engine room, for example, or a water maker. In short, many components can change the weight of a boat. Also, is the anchor counted, or the chain? In short, check the manufacturer\u2019s technical data sheet, and don\u2019t hesitate to ask questions.<\/p>\n

You should also consider the weight of the engine(s) and propulsion system.<\/p>\n

Measuring DRY WEIGHT was therefore an excellent source of information for making comparisons.<\/p>\n

Sometimes the differences are major.<\/p>\n

I can\u2019t resist quoting this example:<\/p>\n

Prestige 520 Fly dry weight: 30,000 lbs (approx)<\/p>\n

Sunseeker 52 FlY dry weight: 60,000 lbs (approx)<\/p>\n

Viking 52 dry weight: 67,000 lbs (approx)<\/p>\n

Yet these are three 52-foot yachts.<\/p>\n

\"Prestige 520 Fly<\/p>\n

\"Sunseeker Manhattan 52<\/p>\n

\"Viking 52<\/p>\n

But the boat\u2019s rather light weight doesn\u2019t necessarily make it any less attractive. I\u2019d say it depends on the intended sailing areas and, above all, the sailing conditions.<\/p>\n

In calm seas or water, with almost no waves, you\u2019ll appreciate almost any boat.<\/p>\n

But in rough water with unpleasant waves, that\u2019s when the yacht\u2019s robustness counts.<\/p>\n

In rough, even very rough seas, I prefer a yacht with a reputation for ruggedness, a real TANK of the seas\u2026(like a Viking or Riviera) or for an express, a Sunseeker or a Pershing of 62 ft or more, but these are personal choices.<\/p>\n

\"Pershing 62<\/p>\n

 <\/p>\n

So, when you want to compare boats, use the DRY WEIGHT measurement.<\/p>\n

Keep in mind that if the boat\u2019s description is DISPLACEMENT only, it\u2019s probably the full weight.<\/p>\n

New materials.<\/strong><\/p>\n

There\u2019s KEVLAR, of course, which reduces the weight of fiberglass by almost half. The same goes for carbon fiber.<\/p>\n

But these two lightweight materials have acoustic effects that are not always pleasant. For example, a carbon hull reproduces noise quite significantly, making the acoustic comfort of rooms on the lower deck very uncomfortable.<\/p>\n

But there\u2019s no problem using these components if they\u2019re used out of the water, as in the case of the hardtop, super structure and transom, for example. But carbon fiber is about 5 times more expensive than fiberglass. What\u2019s more, it\u2019s more fragile than fiberglass in the event of a collision.<\/p>\n

\"\u00a0 \u00a0\"<\/p>\n

We\u2019ll have to look at the advantages in terms of weight versus cost. Italian manufacturer Azimut is the first to use carbon on several models in its range.<\/p>\n

Here\u2019s the Azimut S7 and the carbon fiber gaps:<\/p>\n

\"<\/a><\/p>\n

The use of components that reduce the weight of the boat in its upper section brings definite advantages to the boat.<\/p>\n

A low center of gravity is one of the conditions for a boat to be classified A (CE rating). But there are many other criteria for assessing the characteristics of a boat, see this link<\/a>. A B-rated yacht should not be considered as a lesser quality yacht. You need to look at all the criteria.\u00a0<\/strong><\/p>\n

In brief\u2026<\/strong><\/p>\n

Compare the technical data sheets and don\u2019t hesitate to ask questions if the salesperson tells you: these are top-of-the-range materials, what does that mean!!!!<\/p>\n

Always use GOOGLE to search for the manufacturer\u2019s name and model, followed by the words DRY WEIGHT. Even if dry weight is indicated, do a lot of additional research, as sometimes the information is contradictory.<\/p>\n

Ideally, consult an experienced broker to avoid unpleasant surprises.<\/p>\n
