Ice Yachts in THE BEST #93

New yard for Silent 60
At the recently held Boot Düsseldorf, the Austrian company producing solar catamarans, Silent Yachts, signed an agreement with a shipyard in Ancona, Italy, to produce in their facilities model Silent 60 for the European market. So from now on, the 60 and 80 feet models will be built in Italy.
Silent Yachts currently has 12 high-end electric catamarans in production ranging from 55 to 80 feet with a starting price of 1.5 million euros.
These premium-class electric catamarans provide a unique experience in the sea, being now possible to live it, by testing them at the International Multihull Hull Show to be held in La Grande Motte from April 15 to 19, by sending a prior request. The model that will be present there is the Silent 55.
Also, this summer it is planned to organize a series of sea trials in Mallorca, Baleares, with the Silent 60. Send us email to for more information.

Launching ICE CAT 67
In early March, Ice Yachts launched the second unit of the Ice Cat 67 catamaran, the biggest sailing multihull ever built in Italy. Designed to circumnavigate the globe, the Ice Cat 67 has the RINA certificate and the most advanced safety equipment, the same used onboard the racing trimarans that participate in the Jules Verne Trophy.

ICE 70 Hull#1 is out of mould

Is electric future far away?
I hear a lot that electric boating is our future, but not practical yet. To check it out I compared a revolutionary Silent 80 catamaran of a new, "silent" class of yachts with a most popular power catamaran of the similar size in the market Lagoon Seventy 8.
Buying price with "ready to sail" options is around
4.200.000 EUR ex VAT for Lagoon Seventy 8
4.600.000 EUR ex VAT for Silent 80
Yearly maintenance. Normal usage for the most owners of motor yachts is about 100 hours a year.
⁃ Lagoon as a standard has two 510hp engines. Consumption of these engines is 100l/hour each one, or 20.000l for both engines, 100hours. What is about 35.000 EUR.
⁃ Silent will spend about 2000 kWt of a free solar energy. About 13 days of SunPower solar panels work.
⁃ Lagoon engine maintenance is about 1500 EUR for each one, 3000 EUR in total
⁃ Silent 80 motors will need first small maintenance after 50.000 hour
⁃ Water expanses depends a lot on the region. But not for Silent 80, it will produce his water itself using a free sun energy.
Summing this, Lagoon will spend about 40.000 EUR more then Silent 80 yearly and in ten years all the difference in selling price will disappear.
Don't forget the difference in the construction quality. Silent 80 is 15% lighter, it's vacuum infused carbon reinforced fiberglass, so stiff and light again. All Hull is thermal insulated to avoid waisting energy on cooling or heating. There are important development costs and again, this is new class of boats.
We should of course calculate also a lifecycle of solar panels and batteries. Warranty for solar panels is 25 years, during this time they will not loose more then 7% of efficiency. For batteries warranty is 8 years. During this period they still shall have their 92 % of capacity. Lagoon engines by this time will need an expansive refit, with taking engines off the catamaran and so on.
Silent catamarans are in production from 2009, they are passed already 100.000nm altogether, crossed an Ocean and is proved by time and nautical miles.
And now this is a good question , are "silent" boats a future? Or this future has already happened?

Meet us on BOOT Dusseldorf, Hall 15
If you want to know more about solar catamarans Silent Yachts, visit us in Dusseldorf Boat Show, Hall 15. We will have models of Silent 55, Silent 60, Silent 80 and Silent 80 Tri-Deck models and all the team to explain these unique boats in every detail.

When you google "Disadvantages of Electric Vehicle" one of the firsts will be The Distance Range. But the great advantage of electric catamarans over cars is a huge area available for solar panels. So I decided to find out, what is the real autonomy of Silent Yachts. I know of course that before starting a production Michael Köhler sailed 15.000nm on a test version in 3 years with just 50 hours of generator usage, but how does it fit with numbers?
I started with my favorite spot, Baleares Island, Mallorca, Ibiza, Menorca, and lovely Formentera.
Incident Radiation Flux (the average amount of solar energy per square meter per day) for this region is 5kWh/m2 (
Sun Power panels (all Silent Yachts are equipped with #SunPower 370 #monocrystalline panels with 25 years warranty) efficiency is 22,7%, which gives us 1135Wh/m2 a day, or:
- 53kWh a day (annual average) for Silent 55 + up to 210kWh battery pack
- 75kWh for Silent 60 + up to 210kWh battery pack or
- 115-130kWh for Silent 80 + up to 530kWh battery pack.
Which in its turn gives us about 24 hours of sailing at 6 knots speed, or, if you make usual for cruises 4-6 hours under engine a day, you don't use your battery pack AT ALL. This means UNLIMITED RANGE, which is really impressive!
And looking at a graph from "THE EUROPEAN SOLAR RADIATION ATLAS" we can count on 60-80% more energy than average annual for the summer holidays.
Making this calculations I can say, YES, anyone can do it again with Silent Yachts

We are in THE BEST magazine

SILENT 55 win Best of Boats Award

"suitable for long distance travels with all amendments to live on board permanently, adapted for both inland waters and the tough conditions at sea".
#ElectricBoat #EV #FutureOfYachting

All SILENT YACHTS are powered by two Torqeedo electric 30-250kW engines which are powered by battery bank which, in its turn, can be charged by solar panels. So it's worse to talk about batteries.
Going ahead, SILENT YACHTS catamarans are equipped with 120-240 kWh (28-56 module) MG Li-Ion HE battery bank with lithium rich NMC (Nickel Manganese Cobalt) cathodes, but let´s see why.
There are several types of batteries in the market today: Lead Acid (including GEL, AGM), Nickel Cadmium, Nickel Metal Hydride (Ni MH) and Lithium-Ion (Li-Ion).
The first two types have very low Specific Energy (kWh/kg), 2-3 times less then Li-Ion, in other words, battery bank will be too heavy to give you some reasonable sailing autonomy, although AGM batteries are very popular in conventional sailing and powerboats where electricity consumption is relatively small.
Nickel Metal Hydride batteries were really used in a famous GM EV1 electric car in 1996, and it gave a car significant autonomy of 280km. These batteries had a lot of advantages, they were more stable, a battery management system is simple, they also had a very high specific power (W/kg) what should give acceleration and engine pull-down, but battery bank was still heavy and today Li-Ion batteries are used in a large majority of electric vehicles.
So Li-Ion batteries were chosen to have a light battery bank with a lot of energy, specifically, SILENT 55 has a 120kWh battery bank which weighs just 800kg.
There are also several types of Li-ion batteries, depending mostly on a cathode material and electrolyte (Li-Polymer). Li-Ion NMC batteries together with NCA (Nicol Cobalt Aluminium) have the best Specific Energy, but NMC even more stable and thus safe. This is why SILENT YACHTS power its catamarans with Li-Ion NMC bank.
Silent Yachts battery supplier MG ENERGY SYSTEMS is officially one of the most innovative companies in the Netherland which also won a month ago the Gamechangers Innovation Award, ex Northern Innovation Award. Congratulations guys, good job!
So, to sum up, the formula is simple
More Energy + Less weight + Safety = SILENT YACHTS

In the yard
We are in the Ice Yachts shipyard again and this visit promises to be especially dense and interesting. The idea is to know better a boat line from the strategy point of view, but also to know better a manufacturing process.
The first day we made a walk around shipyards, Ice Yachts has two of them. In one Ice Yachts produces now a HULL №1 of ICE 70 and ICECAT 67 catamaran. In another, ICE 52rs, ICE 54, ICE 60 and the deck for 70ft. As I already know quite well Ice Yachts monohulls, I was more curious about ICECAT 67. The boat is in the last phase and should hit the water already in January.
From the first look, you understand that this beast is unstoppable. It is really big, the biggest sailing cat built in Italy, and it looks very fast. The weight of the hull is just 8.5 Tonnes! (real weight, checked after lamination) But, as this boat is going around the world, it has a lot of equipment, including two 600l/h water makers, diving compressor, 3kw windlass, two Watt and Sea hydro generators, ten solar panels and a good pack of Li-Ion batteries. Although catamaran is smaller than 24m, it is certificated by RINO class society, what the client wish. And with all these upgrades it still will be below 23 Tonns, full equipped.

We open our doors in port Balis
New office of Yacht Consulting Barcelona opened it doors in Port Balis (Sant Andreu de Llavaneres). Here is what press tell about us:

" Yacht Consulting Barcelona - official distributor in Spain of ICE Yachts and Silent Yachts

· ICE Yachts produces elegant high-performance cruiser/racing sailing yachts up to 82 feet in Italy.
· Silent Yachts is an Austrian shipyard, a pioneer in the construction of electric-powered catamarans.

In the Port Balis, in the province of Barcelona, a new nautical company has just opened its doors, Yacht Consulting Barcelona, official distributor in Spain of two shipyards that are reaping international success: the Austrian Silent Yachts, manufacturer of the nautical "Telsa" - ocean-going catamarans that have highly efficient solar panels for their propulsion - and the Italian ICE Yachts, producer of cruiser-performance sailboats from 52 to 82 feets, combining high performance and maximum comfort.

In December 2019 the first ICE 62 was sold in Spain to sail the waters of Barcelona, while another model in the range, the ICE 52rs, is currently under construction and will be delivered in Valencia for summer 2020. Among the many successes obtained by the yachts of this Italian shipyard, we highlight three first places of the ICE 52rs Prima Vista in the last Rolex Middle Sea Race, in the Coastal, ORC 2 and IRC 3 categories.

Palermo - Monte Carlo
Winners again!

The 15th Palermo-Montecarlo was a particularly challenging edition due to the conditions and exceptional heat that kept tacticians on their toes from start to finish.
Primavista Lauria, the Circolo Canottieri Roggero di Lauria boat, was overall winner in corrected time, despite finishing 7th in real time. It is the fifth time the ICE 52 has won this contest, a world class team that included Sandro Montefusco, Matteo Ivaldi, Andrea Caracci, Sicilian Giuseppe Leonardi and Mario Noto pulling off a tactically perfect race.
