    So, what ideas do you have for your mailable boat?

    The 9M is on a trailer. I have no shortage of trailers 3. I have no shortage of boats 6 (3 kayaks). I have simply concluded that smaller boats get more use and provide more value.

    When I have it to sell I will have it to show. I think there is more value to starting with manufacture to establish one design. Home or kit build can be considered by the class or if manufacture flops.

    By mailable I mean no parts longer than 6ft -that's where premium charges start. I think airlines charge a premium for luggage over 50lb but something 6ft might already pay. Existing breakdown kayaks tend to target 3ft storage length. 4ft would fit inside almost all cars. I am not sure about urban bus and rail but they take bikes now. Charter bus no problem.

    Another idea I have is that the ability to go from paddle to sail to paddle in seconds on the water and that this allows the sail to be designed for higher wind when it is needed. Wind gets annoying to paddle into between 7 and 10 knots. This is where I want the user to be able to deploy the sail and be able to sail near hull speed and tack through 90deg. This design is more for adventure race/tour than sail regatta which could be offered later with higher performance and price.

    Good luck.
    If you can pull that off it will be a winner. :D

    Some inspiration for mailable boat :) May be not very mailable due to 150 kg dry weight, but can be disassembled in three 160x60x60 cm packs, can be sailed and rowed. Made from Al-Mg alloy.
    It's Yantar (Amber) trimaran from USSR.

    The weight seems a bit excessive for strong alloy. I suspect the cost follows the weight up. It does look like a very capable expedition craft for two though. It looks like it has a serious rowing configuration for two with the floats retracted. I also suspect that the three packs of boat have room for additional equipment. It would be better if they stored in one pack 160X60X80 but the three packs serve as suitcases in shipping. It has another attribute I want in my designs -a bottom that does not depend on highly stressed fabric -safety should not depend on air pressure. Leaks are too common with age. I don't even like stressed skin over stringers below the waterline but it's better.

    Thanks for sharing what's going on with portables in Russia NNNN. Maybe we need a portables thread....

    :) As it was usual in USSR, Yantar was built as side product of large shipyard. Main occupation of this shipyard was missile frigates and LST building. I think, they used the same designing approach and some spared materials on this trimaran.
    To spare place in packs you can replace hard floats by inflatable, for example.
    But the use of PVC/fabric gives great improvement in “mailability”, IMHO. For example, sail, floats, rudder, dagger and some other parts for boat on the picture, were transferred from Russia to Thailand by plane, then boat was assembled using local bamboo, sailed in Аndaman sea, disassembled, and valuable parts were returned back.

    You can ask hob from this thread about details.

    Lack of personal cars and not great road network in USSR created great need in boats, which could comply with 220 cm public transportation limit.

    hi, the main hull sits well in the water in light winds .but it tends to dig in in strong winds (white caps ) no matter how far back i sit

    Corley epoxy coated

    Maybe you should install a water ballast tank in the back of the main hull like the big French maxi trimarans :).

    I'm not familiar with it Nigel. But is there an active fleet in your vicinity? I'd always opt for a boat I can race with locally, and then preferably a 2-handed craft.

    That's one of the things that fortunately led to my domestic bliss. My wife-to-be was the absolute best crew of all the many people I'd sailed with.

    :)
