    here is video about various mesh tightening procedures I used,

    http://www.youtube.com/watch?v=Z5rkS2j9rDU

    seems to me that it should now be ready for plastering.

    seems as though I only have enough for 0.25 cm thickness.

    Any last suggestions before going ahead?

    applied the concrete today, I finally did manage to cover up those remaing little holes, it was finding a piece big enough, that was sufficiently adry to keep shape, and yet wet enough to reintegrate with other parts of boat, for lack of better water source I spat to help meld some of the plaster.
    it’s raining now and will be for next week, helping to cure the cement.

    Earlier Frusha was saying should cover boat with burlap for curing,

    burlap is too expensive for my purposes so I used an old bedsheet.

    covered boat with bed sheet, a standard twin size polyester sheet.

    ferrocement dinghy concrete boat – boat flip, cement mixed interior pasted

    http://www.youtube.com/watch?v=sxdreQaNqCE

    lessons learned: can use less cement on exterior, due to effectiveness of concrete from interior.
    have abundance of materials or fuel, 1/3 extra is a good reserve.

    nice work spru. my suggestion is that you need more than just a way to get it to the river. you need a way to get it to and from the river multiple times. keep your eye out for a small boat trailer on craigslist and ebay – eventually you might find one extremely cheap. i got a stackable washer/dryer for my condo for $380 and it was worth about $800.

    also- make sure you push it out slowly into the water, especially the first time. if there is a leak, u REALLY dont want to let it get water-logged out in the river before you can pull it back in.

    also also – as a former boy scout with tons of safety training i feel like it might be wise to have a lifejacket and use the buddy system. only 1 or 2 buddies. things can get out of hand faster when theres a crowd of people looking to be entertained.

    rootin for ya, dude! (safely from the river bank)

    It takes time to cure the cement…

    Have you looked at liveaboards and traditional (primitive) boats? Look up the Moken people, of Thailand and their boat, the Kabang. Traditionally, they lived at sea for about 9 months out of the year, coming ashore for repairs and to build more boats, gathering some supplies, for spiritual reasons, etc.

    I’m trying to get someone to draw up the design. Then, maybe I can produce one in ferrocement, one we get a small family farm up and running (I have 5 kids)…

    Samta and I went over to flip the boat,

    sat in it for a while, celebrated our boat, listening to radio, eating fruit, toking.

    then we watered the boat and moved it over, as we were preparing to leave I remembered to make a video.

    since then it’s been raining so haven’t visited since, might check up on it soon though, see how much water it’s holding, and repair what can benefit from it.

    it’s interesting how they have the lower jaw there.

    it could probably be straiaght down like on a square boat,

    though it open opportunity for having a movable jaw set up in similar position.

    Traditionally, they lived at sea for about 9 months out of the year, coming ashore for repairs and to build more boats, gathering some supplies, for spiritual reasons, etc.

    that’s beautiful,

    we were planning on having some land time also. seasonal nests kinda thing.

    I’m fairly certain there is insufficient freeboard for open ocean,

    for the safety of your family it would be best to have a waterproof shell that can handle temporary submersion.

    I do like how simple the design is, and the house is quite interesting, I was also thinking of making a hexagonal structure,

    though perhaps a pentagon would make for more deck area.

    Maybe something thrice the length and thrice the girth and coated with ferrocement rather than full ferrocement so they could handle most of the building?

    I wonder how much these cost to commission from the Moken? The only other thing is to find a proper colony spot to raise land at. Still want to be in territorial waters though?

    9 months in and around the Indian Ocean, with several months ashore, during the monsoons.

    The notch at the bow helps it cut into the oncoming waves. Look up “bifurcated bow”…

    Just because you don’t have faith in it doesn’t mean it’s untrustworthy. Generations have trusted them, who are you to judge? What makes you the almighty-of-the-sea? Everyone shoots everyones ideas down, so not a damned thing gets accomplished. If it’s a ‘next-step’ beyond the ferrocement dingy for you, it may well serve the purposes others have need of.
