    Yes very nice progress. I guess he enjoys building this boat more than the other one he got cold feet with. He definitely did the right thing. It is always good to change direction in life when something is bothering you or doesn't make you happy.

    She looks very capable. I don't think it will take her too long to be ready. She looks to be capable of making the trip in something even smaller, with less stores. Go Emma. Reminds me of The Secret Sharer by Joseph Conrad, where the skipper risks the ship in order to get closer to shore even though the other fellow is an excellent swimmer. I am afraid Sven may be making the classic mistake of designing for his current capabilities instead of hers. No doubt he will be with her in spirit on her voyage. :)

    :) I like Svens work and I read every word that he writes 10 times over, and I take everything in with the greatest care and respect, always food for thought and good advice.

    Ex Lex is looking good but every time I look at her I realise that she is very very small.
    But as always I love Sven :)

    Sven doesn't seem to be afraid of a bit of sanding . . :cool:

    I'm sure that's strong enough, and in reality it will be even stronger as Sven explained in the text. But the test is with a static load, the real load will be dynamic I think. A dynamic test could be to tie a realistic weight on the rope and drop it from a realistic height. Or maybe use a chain, because the stretch in the rope will mute a part of the impact.

    P.S. - Re chain: If a rope is used for the real attachment then a dynamic test with a similar rope of the same length would be realistic.

    He will be using these screws only to hold down his anchors so that will be plenty strong I guess.
    He could easyli made a "box", lay the anchor on top of some divinycell, draw the contour around it and remove the inner section. Lay a few sheets on top of each other so that the removed cavity is deep enough to let the anchor sit in it. Epoxy this "box" to the floor so that the anchor cant move sideways and only the screws are needed to hold it down. The screws can be fiited in the "box" so no need to drive screws into the boat hull.

    Sven is changing his mind almost on a dayli base...:D but why build a bigger boat if the one you're building will suit your needs....
    She certainly looks strong enough and Sven can survive on a diet which most of us would give up ...after 2 days LOL !!
    Perhaps he has just enough storage room for his supply's and drinking water.

    Agree.

    The only downside I can think of is that the outside of the anchor box will "eat" some more of the interior space than the anchors alone. I do like the idea not to drive screws into the hull.

    Agree.

    2,100 calories a day looks pretty realistic to me. Less than one liter water a day is not much, but Sven is experienced enough to know how much he uses.

    Maybe for emergencies it would be an idea to carry a hand operated water maker. It requires a hell lot of pumping to get a liter fresh water out of it. But it will earn its weight on board because you can do with less distress stock of fresh water, and if needed it's able supply more water than what is spared on the distress stock. Of course it will need to carry enough spare parts for the watermaker, or maybe even a spare one.

    I've randomly picked some from the web . . .

    Here's a thread about Carbon Fiber Chainplates, maybe in customized sizes that's also an idea for other attachments inside or outside the hull.

    The above boat is an Wharram Ariki catamaran professionally built in modern materials by BoatSmith in West Palm Beach in Florida.
