I have been thinking about auxiliary propulsion and the implications on construction, storage, budget and use when participating in official 5.80 ocean races vs cruising. Would very much like to hear your thoughts and ideas.

When we release the Notice of Race for Globe 5.80 Transat and Mini Globe Race you "MAY" find we do NOT allow rowing or Paddling when racing unless an emergency. You "May" also be able to use your electric outboard any time during the race. WE have thought about this for a long time and it is a conscious decision if we do, based on the fact that the whole subject of electric outboard, solar panels etc is an interesting one for the future. So you can see this opens up an interesting challenge. This opportunity would NOT be allowed for shorter courses with the 5.80.  |

Ok, just learned that Transats and MGR races will be electric propulsion only. (I missed that announcement somehow earlier). This helps with defining my build direction.
Just need to see what the CAT 1 rules will allow if I try to leave New Zealand with an electric set up. Currently no provision is made for electric propulsion in YNZ Safety Regulations of Sailing! So will be pushing the boundaries of the legislation and decision makers.
Currently there are rules about how fast the boat must be able to travel in smooth water coupled with the amount of fuel you need to carry, which combined will give a range. Any electric set up will have to meet or exceed these requirements... I am guessing...

If you give them your own safety management plan I think you will be surprised as they let rowers go without an engine and the rule is generic to the usual boat/yacht...not a 5.80 yacht that is perfectly seaworth?? but who knows good luck! |

If electric outboard is allowed in complement to sails, I do not see a reason to forbid man powered alternatives. On a boat this size I would go without engine but would take an oar in case of very flat. |

You will see in the Notice of Race when released that you must have an alternate steering and a rowlock, plus Paddle or oar onboard for EMERGENCY propulsion/steering...but manual propulsion during any Race will be forbidden. If not people will set up for serious rowing or peddle bikes etc and we do not want to go down that path. |

I Unterstand the Logic although I am a bit disappointed not to be able to skull in a race. It will be for a next occasion. Then if we can use the electric engine this is becoming also very insteresting and maybe more coherent with the design of CG580. I am not sure if electric engine can become a strong competitive advantage in a transat type of race. Maybe yes to position yourself in a weather system before the others. This could become A new way of sailing that could be advertised more as core element of CG580 However this migh also become a costly tech race to get the most of solar energy. I like the eco-innovation component of this race. I have seen a max power for solar panels. Do you also plan to cap the battery capacity ?

Yes AGM/GELL 165amp maximum capacity for the 5.80...all to be announced in the Notice of Race...using your outboard in the Mini Globe Race will also be an important part of the Race logistics and concept of the pitstops etc. All to be announced in NOVEMBER ...Thnx... ... |

Hi Don
with my 650 sailing sport boat boat - weight Kgs 700.- i got a torqeedo 1103 CS with 915 Wh battery
this allows me (without waves without wind) to run 3.3 knots for approx 2 hours.
when it's really windy the engine is not
is someone can tell me how long a 100w solar panel will need to fill up the battery.
Electrical engine is green power energy but not very powerfull
For the Panama channel - this will not be enough as it is a full day running at min 5 knots as far as I remember
thanks

Electrical engine is green power energy but not very powerfull For the Panama channel - this will not be enough as it is a full day running at min 5 knots as far as I remember thanks HI.. The 1000watt motors that will be allowed for the Transocean events are only meant for light winds and getting off docks etc..if you slow down the battery will last longer ofcourse and you would be able to carry one spare OB battery doubling range again....so if there is wind the Globe 5.80 is a 'handy yacht" able to spin on a top and easily manoeuvrable, and sails ok in light air, so yes if it is blowing hard and you do NOT want to sail you may have a problem....but you have a storm jib? ..or you have to think about what your doing....The Panama for MGR all boats will be trucked across as your too small to go through and it would cost a fortune...a 100 watt panel at 18v will output about 5amps at max sun 90degree angle 20c temp day ...so it you have a 100 amphr battery that was 50% charged at the start, your looking at about 10 hours charging in a simplistic world?? amusing you could pour all that power into the battery, but you cannot, as the voltage will increase and the regulator will slow the amount of input as the last amps going in can take some time.So to top right up may take 20 hours or longer??.there are plenty of videos and info on Google/Youtube about how AMPS, VOLTS and WATTS work in relationship to each other and it is something every sailor should know?? ...the 5.80 is a sailboat and the electric motor is Eco friendly and an aid...not necessarily the answer to everything, but OK.. just sail and passage plan within your limits and that of the 5.80 with an electric motor...good luck! |
