Did we loose the OP?
No you didn't loose me. Thank you all for the amazing inputs and ideas. No I wasn't scared off by the comments, on the contrary I've rather enjoyed the discussion it has sparked, I've just been busy travelling around Southern Africa living out of a 1989 Toyota Cresseda. On the road I came across a lady who runs a backpackers and feeds her guests from her small veggie garden. We spent over a week there and didn't have to buy food once, learning how to preserve surplus into chutney, jams and pickles we left loaded up and were still eating from the bounty two weeks later in Mozambique. Which is exactly the thinking behind growing produce on the boat or on land when anchored up for longer periods, when it is time to move on one harvests all and preserves it using old tried and tested methods... We seem to forget modern refrigeration is less than 200 years old and we have been crossing oceans a lot longer than that.
Now look all you nay sayers there is a way to do it.
Go to Rio Dulce, Hurricane hope, fresh water, few authorities.
Build a bit bamboo raft with a bit on top. Build it modular.
Every year build two new modules and shift stuff to the new raft section.
No need to maintain the old sections, just build faster than they rot.
There you go, a big flat floating platform that needs no heat or AC. Small waves, no salt, minimum wind.
Then you can build your farm on top.
Of course you will go nowhere but I didnít see the idea of traveling featured prominently in the OP.
Bored and grumpy today.
hpeer we also watched an amazing documentary on a fella who has done just as you describe only he uses trash.
While an incredible feat, I'd look to be somewhat more mobile. Though it does talk to a point I think many on this forum seem to miss. From how it reads here most people here live on their boats part time, sailing under a schedule, with homes and families to get back to. My intention would be to stay in one place for much longer periods of time, the boat would be my home and my main means of travel. Which is why the consideration of where to buy is important as I'd likely spend a few years around the area before venturing further afield, only moving on when required or the itch arises.
Joking aside I bartered seafoods for garden produce for many years of coastal cruising. Canning and drying when excess of daily needs. No regular job as I was good at fixing others stuff.
This is exactly my thinking. There is clearly no way to grow all food needed on a 35-40ft boat. Things like grains and flours are just not feasible. Though if one could trade for them it is all the better. Plus that would just be the intention where possible, there will obviously be produce purchased where needed.
Pulled out my Westerbeke diesel ten years ago and replaced it with electric propulsion. Was a leap of faith back then but, would never go back to diesel now. Maintenance costs dropped to near zero compared with diesel. Bought a Honda 2000 generator for charging in case my solar and wind systems can not meet demand. Use it much less than I thought I would. Best part is I can make fuel (energy) while underway (and at anchor) using solar and wind and if I start getting up near 6 knots regeneration with the prop. Another nice thing the boat smells clean since their is no diesel or antifreeze on board to spill and just a little oil for the Honda generator.
Thanks so much for chiming in and all the valuable info. The more I investigate the more I see EP is the way to go. You say batteries have not come along since your system, but listening to the Tesla earnings call yesterday I'd have to say that in the last couple years they have drastically come down in price and availability. Not only can one now find used electric car packs, as someone else in this post mentioned they are becoming more readily available, but there are tons of old laptop and consumer electronic batteries that can be picked up at a steal and converted into a pack. There are even kits available to make the packs https://www.kickstarter.com/projects...65/description
Also researching solar, in the last few years panel prices have dropped exponentially, whilst getting far more efficient. That 10 or even 5 year old 100watt panel you have that cost a thousand dollars probably only had about 10 to 12 percent efficiency. You can now buy a 400 watt panel with 20 percent efficiency for around $400. Not to mention thin film solar which can greatly increase the available area in which one can capture power.
The more I've researched the more possible this idea is becoming. The next step is to find the right boat. I was looking in the States, but realised that like so much over there where everything is about money and profits, taking little regard for the environment and people, so too have many of the boats been designed. They often tend to be of lesser build quality and poorly maintained compared to their European counterparts. As to when approaching sellers, the European sellers seem to want to go out of their way to help potential buyers and are more excited about welcoming a new member to the salty community than about making an extra penny on the sale. This obviously doesn't go for all and there are plenty of American sellers who are similar in attitude. This seems to come across on these forums too. There are those who are simple at heart and do it for the love and freedom of the ocean, wanting to share that passion with all, they seem to understand that life is not about rushing from one place to another and would rather be under the power of the wind than a smelly engine even if it means moving along at 1kt. Then there are those who seem to think that having a boat is about showing off to neighbors, a toy to take out during the summer break and have to get back to the dock by 5pm less they miss their t-off time. To each their own, but I firmly fall into the first category and am excited to see where I can take this idea...
