Diy Canoe Building Plans Meaning

Jimmy Cornell reports on his new catamaran, aboard which he plans a fossil-free circumnavigation. As we left the marina, grey skies hung low over the bay of La Grande Motte and it felt more like being in the North West Passage than the south of France.

But once the sails were up, Aventuraa bespoke version of the Outremer 45, came alive and the magic took. As I took hold of the wheel, I felt a surge of mixed emotions: excitement, satisfaction, but above all a great relief that my complex sailing zero boat zip challenging zdro has become reality.

I also felt 30 years younger. Barely a year ago I realised that my active years were soon going to be over, and I ought to do something special, but also relevant, while still able to do it. This is how the idea was born sailing zero boat zip a sailing zero boat zip the world voyage in a fully electric boat sailing zero boat zip the route of the first circumnavigation years ago.

As I explained in a previous reporteven for a dyed-in-the-wool monohull sailor like myself opting for sailing zero boat zip catamaran seemed to be the best solution for the voyage I had in mind.

A performance cruising catamaran would be fast under sail and thus able to generate electricity; it would also have sufficient surface available to display several solar panels. Strangely enough, when I was planning my first voyage in the early s, it was a catamaran that I believed would be best suited for a family with two young children.

In those days, the UK was at the forefront of multihull development and there were several boatyards producing cruising catamarans. The Snowgoose sailing zero boat zip and Iroquois looked very tempting, but when I approached the builders and told them that I could only afford their bare shells and would finish the rest myself, they both refused.

Larger new cruising yachts, especially those at the quality end of the market, have been sailjng fitted with lithium boat�. Every sailor is familiar with the wet cough of the diesel engine, and the acrid smell of its exhaust.

The essential feature of an electric boat concept is not its propulsion but the ability to produce electricity while sailing.

While sailing, the propellers on the two saildrives are turning and producing electricity. This is the concept of electric regeneration. For reasons of security, Aventura has two different propellers. On the starboard side a variable pitch ServoProp, developed by Oceanvolt, is very efficient in producing electricity. The Gori folding propeller on the port side is less efficient in producing electricity but more efficient for propulsion and also more robust in case of a collision.

This is the potential weakness of the ServoProp and the reason for having zzero this compromise solution. Initially, I had been told by Oceanvolt that we could expect an average charge of W at 6 knots and W at 8 knots, which sounded quite reasonable. But once Sailing zero boat zip got into her stride, we were achieving double those values, and much more at higher speeds.

Indeed, as our speed moved into double figures the ServoProp was charging the batteries at over 2kW, which biat beyond my highest expectations� until Aventura caught a wave, started accelerating, the speed climbed to over 14 knots and the figure on the gauge shot up to 6. The test also confirmed that the Gori propeller was much more efficient for propulsion, consuming less than half the electricity at the same revolutions than the ServoProp, while the latter produced on average as much as four times more electricity in regeneration mode compared to the Gori.

A key feature of the Oceanvolt set up sailng its remote monitoring and management. The entire Oceanvolt installation on Aventura Zero can be monitored in real-time over the internet. Thanks to this technology, Oceanvolt engineers are able to diagnose and deal with potential faults remotely from their base in Aero.

Via the remote interface sailinv is possible to sailing zero boat zip overall power consumption and charging of saliing battery banks by hydro-regeneration or solar panels. A pleasant surprise for Cornell and the test team sailing zero boat zip the display confirms the regenerative power coming from the Oceanvolt drive. Having tested the Oceanvolt system, and with any concerns about its efficiency laid to rest, we spent the rest of the afternoon sailing up and down the bay, tacking and gybing in winds sailing zero boat zip 15 sailing zero boat zip 18 knots.

With my monohull mentality, and aware of the speed potential of this type of cat, my main concern was how to sailing zero boat zip matters under control quickly and efficiently when the need arose to depower the boat. When I sailed last December from the Chesapeake Bay to Puerto Rico sailing zero boat zip an Outremer 5X rigged purely for racingit took the three of us half an hour to put in a reef.

Now, with a simpler deck layout and the undisputed advantage of a rotating mast, we did it in 70 Foot Sailing Boat Zip less than half that time. And this is where I had the greatest surprise, not of the day but of the entire testing sailing zero boat zip. Plenty of deckspace allows for 1,W of solar panels. I must be dreaming, I thought, before taking a photo to look at when I woke up. A balmy day with a veritable Mediterranean sky worthy of a Cezanne painting smiled upon us as we left port the next day to continue testing the sails and deck layout.

Lights winds and little swell provided ideal conditions to test the Code 0. Made of Aramid laminated cloth, it set beautifully and, once again, Aventura amazed me with her speed sailinng. Reaching in 10 to 14 knots of wind we were soon achieving the same speeds through the water.

A sudden burst to He believes more multihulls should carry. The latest is my fourth, as I am absolutely addicted to this versatile sail, which I can easily raise and douse on my own, as I did on this occasion.

For reasons that I cannot understand, Parasailor is little used or voat known among many catamaran owners, so here was an opportunity to put this right. A fluky wind puffing between 5 and 10 knots offered me the ideal conditions to attempt to persuade my doubtful audience � Outremer sales manager Matthieu Rougevin-Baville and delivery skipper Julien Calvet.

The m2 monster played its zeor to perfection: it stayed full and steady in those light winds, and exceeded even my expectations when it kept Aventura moving at 6 knots in little over 7 knots of true wind.

Conor Dugan and Taylor Esposito are both Americans and sailing zero boat zip spent many years in the charter business in the Virgin Islands. My third crewmember is Michalis Zacharias, an experienced Greek sailor, who is just as excited at the prospect of a long voyage on such a boat.

Besides its outstanding performance, Aventura Zero also promises to be a comfortable home. Being fully electric will certainly add to that, although it will force us to adapt to a different lifestyle.

That certainly applies to the way we shall do our cooking, and keep an eye on the electricity consumption of such hungry items as water heater, hot plate, oven and breadmaker, all of which run off V. The main energy storage is provided by the two propulsion battery banks of 28kWh. The service battery, which supplies 12V to the electric winches, windlass and toilets, lights and various pumps, is recharged continuously from those banks.

As both battery banks are recharged continuously by the solar panels, with a total capacity of 1,W, it makes sense for us to sailing zero boat zip in the middle of the day, when their output would roughly equal that of consumption.

As we shall sail several long offshore zer, conserving fresh provisions is a high priority. The two fridge-freezers on Aventura Zero have a drawer-type mechanism which are much more efficient than the front-opening domestic type fridges used on many yachts today.

The latter has its own Triton display, GPS and wireless wind sensor, and is part of an emergency zer entirely protected from the rest of the boat. It also has its own battery and Sail-Gen hydro-generator. Satellite communications will be provided by Iridium Certus, the fastest L-band maritime service available.

Throughout the voyage we shall automatically send data on wind speed and direction, barometric sailing zero boat zip, water and air temperature, to the World Meteorological Organisation, just as I did from the North West Passage. Zop Cornell is marking the th anniversary of the first round the world voyage by sailing the same sailing zero boat zip as Basque sailor Juan Sebastian Elcano.

His aim is to do so in an electric boat with a zero carbon footprint and he plans to set sail this November. A late addition to my range of electronics is OSCAR, an anti-collision device that detects floating objects up to m ahead, whether Small Boat Sailing Vessel Zip small boats, whales, containers or any other flotsam that could present a danger. It greatly improves safety both by day and night, and is the first navigational aid system based on artificial vision and intelligence.

It is equipped with a Torqeedo C electric outboard with a long-range, high-capacity W battery. The davits carry a lightweight 3.

With autumn sailling fast and sailing conditions to the Canaries rapidly deteriorating, as soon as our tests and preparations are completed we shall sail for Seville and the symbolic start of our journey. After a brief stop in Tenerife sailing zero boat zip shall sail non-stop to Punta Arenas, in the Magellan Strait, a 6,mile leg that should prove that both boat and crew are worthy of following in the wake of our daring sai,ing.

First published in the December issue of Yachting World. Sailiing this report was published, Jimmy sailed to the Canaries, but during this passage came to the cruel realisation that the regeneration system was not going to give him the power required and had to make the difficult decision to return to the yard in France to evaluate.

The Code Zero is a cross between a genoa and an asymmetrical spinnaker that is used for sailing close to the wind in light air. This particular Code 0 was made for a 52 Ft fast catamaran. It was the fastest sail of the inventory and with it I was often able to reach and maintain wind speeds. So, in a 20 kts breeze I would reach 20 kts boat speeds.
