Review of Moody 346

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The Moody 346 has been built with different keel alternatives.

Shallow keel

One option is a shallow keel. A shallow keel allow to sail both coastal and inland waters.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can enter even shallow marinas as the draft is just about 1.14 - 1.24 meter (3.74 - 4.04 ft) dependent on the load. See immersion rate below.

Another option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

This keel is also made of iron.

The boat can enter most marinas as the draft is just about 1.52 - 1.62 meter (4.99 - 5.29 ft) dependent on the load. See immersion rate below.

Moody 346 is typically equipped with an inboard Volvo Penta 2003 diesel engine

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Moody 346 is about 202 kg/cm, alternatively 1135 lbs/inch. Meaning: if you load 202 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1135 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 30m 2 (322 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

Tomsk-7/Seversk, Russia

The explosion of a nuclear reprocessing facility in Tomsk-7 dispersed large amounts of radioactivity over an area of 120 km² , exposing tens of thousands of people to increased levels of radiation and contaminating air, water and soils for many generations to come. It is considered the most serious Russian nuclear accident after Chernobyl and the Kyshtym accident at Mayak.

Tomsk-7 was a “secret city” in Siberia until 1992, when it reverted to its historical name of Seversk. It housed several nuclear facilities for large-scale production of plutonium and uranium for nuclear fuel and weapons, including reprocessing of spent fuel. The closed city was home to about 100,000 workers and their families. One of the worst accidents in the history of the Russian nuclear industry occurred at the Tomsk-7 reprocessing facility on April 6, 1993. That day, workers were pouring nitric acid into a tank in order to separate plutonium from spent nuclear fuel. It is not clear whether the accident was caused by human or technical error, but it is believed that a lack of compressed air caused the mixture of nitric acid, uranium and plutonium to overheat and reach critical temperatures within a few minutes. The ensuing explosion knocked down walls on two floors of the complex, started a fire and released about 250 m³ of radioactive gas, 8.7 kg of uranium and 500 g of plutonium to the environment. This amounted to about 30 Tera-Becquerel (Tera = trillion) of beta- and gamma-emitters and about 6 Giga-Becquerel (Giga = billion) of plutonium-239. An area of 1,500 m² around the plant was severely contaminated, while the radioactive plume covered a total area of 120 km², where increased levels of radioactivity could be detected. The explosion at Tomsk-7 was ranked level 4 of the International Nuclear and Radiological Event Scale (INES), comparable to the Tokai-mura nuclear accident in Japan in 1999.

Health and environmental effects

Most acutely affected by nuclear fallout were the villages of Georgievka and Nadezhda. Radioactive snowfall in the days after the disaster created hot-spots with radiation levels of up to 30 µGy/h – approximately 100 times normal background radiation. Soils in the areas affected by radioactive fallout showed significantly increased levels of long-lived radioisotopes such as cesium-137 or strontium-90. Cesium-137 can cause solid tumors and genetic defects in offspring when inhaled or ingested through food or water, while strontium-90 is a known cause for leukemia.

With the help of foreign specialists, initial clean-up operations were able to collect and remove about 577 g of plutonium from the area around Tomsk-7. Interestingly enough, only about 450 g of plutonium had been present in the basin before to the explosion, suggesting unreported prior plutonium leaks from the facility. Even months after the explosion, snow samples continued to show increased levels of radioactive isotopes such as plutonium, uranium, zirconium, ruthenium, cerium, niobium and antimony, continually exposing the population to radioactivity. According to the Bellona Foundation, a Norwegian environmental NGO, about 30 major accidents occurred at the Tomsk-7 nuclear facility, releasing about 10 g of plutonium into the atmosphere each year. The NGO also documents large quantities of nuclear waste from 50 years of plutonium production, which have accumulated on the confines of the nuclear facility. Dumped into underground depots or pumped into uncovered holding pools, they pose a continued threat to health. In 2008, a study found increased levels of plutonium and cesium-137 in soils and water samples, suggesting further leaks.

Some reactors at Tomsk-7 were shut down in June 2008, following the 2003 agreement between Russia and the U.S. concerning the elimination of weapons-grade plutonium production. The reprocessing of spent fuel and the dumping of nuclear waste on the premises of what is now called the Siberian Chemical Combine continue to this day, however. Despite the findings of increased levels of plutonium, strontium, cesium and other radioactive particles in soil and water, no meaningful medical studies were performed on the local population. In 2001, a county court in Tomsk ruled on a lawsuit by contaminated inhabitants of the village of Georgievka against the Siberian Chemical Combine, deciding that the company was to pay each claimant a compensation sum equivalent of 860 US-Dollars. During the hearings, 14 of the 26 claimants passed away, according to the Bellona Foundation. Their health was compromised for the production of nuclear fuel and nuclear warheads. They, and everyone else in the area whose health was affected by the catastrophe at Tomsk-7, are also Hibakusha.
