    Annie, I'm surprised and impressed that you've managed to add as many hull panels as you have without assistance. Now's the time to find some tame Kiwis to help with those awkward bilge panels. Maybe I should have designed the hull a little narrower - I thought that the first after panel would be about three-quarters of a sheet. Or made the flat bottom a bit wider, but that would have made her less sea-kindly.

    Yes, Annie,

    Epoxy is not my favourite stuff to work with, but sometimes I see no other method. I do my best to minimise sanding  - I rather have a little uneven finish than spending time with producing a lot of dust (also with wood  -  real boatbuilders mostly use axes and planes instead of angle grinders and power sanders).

    The pumps for epoxy are all right when frequently used, so the stay primed  -  mine never did that.


    BTW, I once made a sample of West epoxy, mixed to 4:1 and another to 6:1 and they both appeared to be good. I don't know how strong they were, but at least, they did not end up as the god-awful "jam" one gets if the mix is all-wrong. Guess how I know this...

    PS , today I had a glorious sail in Frøken Sørensen. On a broad reach, with one reef, we reached 7.2knots  -  twice! Best until then was 6.8knots. Today's temp of 25 degrees Celcius feels unreal in Stavanger, this early, but in a couple of days we are back to normal. Tomorrow I must order aluminium for Ingeborg...

    Thank you, Arne, you're very kind.  Actually, I doubt I'd even get a C, but epoxy is very forgiving stuff.  The final fairing was scaring the wits out of me - if it's wrong, it's a bit of a disaster, so my friend Marcus has kindly stepped in to do it.  This is even kinder than it sounds, because he is horribly sensitised to epoxy and usually keeps as far away as he possibly can from having anything to do with it.  For people like him, there is no such thing as 'cured' epoxy.  With the best will in the world, there are always some molecules that escape and effectively stay volatile.  As soon as the 'cured' epoxy is hit with sander, scraper or plane, they escape and do their worst.  Mercifully, this is my last big project with the stuff - I just hope I get away with it.

    Scales are a good way to go, Arne, and undoubtedly the most accurate.  However, I stick with the pumps - they are easier for me to use and, of course, the only way to go when afloat.  Not, that I intend to be using them very often when that wonderful time comes!  I hope you had a marvellous sail in the warm sunshine.  Believe it or not, our afternoon temperatures are still in the low 20s!

    Hi Annie, it works for me, as well . I just click on the photo.

    I see you are about to close the hull. You are good! I never got more than (the equivalent of) C in carpentry, so would have been of little help, except at stirring glue. On my small gluing jobs, I use a digital scales, pour in the hardener first and then just multiply with 6 to get the right total weight (West epoxy). Today we are in for +25 degrees here, which may well be one of the hottest days this year. I guess I'd better go sailing :-) ...

    I meant in a nice, neat form that you could just click on.  But as long as anyone interested can get there, it doesn't really matter that much.
