    I can assure you that i realised that its a small boat or nothing, first reason costs, second reason is singlehanded. My last time at sea was on a 36 Beneteau in very bad weather with FIVE crew on board vomitting their lungs out. We were on a third reef in the main and it was up to me and our very capable young instructor to get back to Durban harbour. That was when i learned i would rather be out at sea alone on a small "egg" much better with only myself to look after. I will be spending my money on the nice to have stuff - radar - AIS - good instruments, composite mast. When you build a small boat you can actually dream about buying the cool toys for the boat.

    I stepped the joints with a router
    half the thickness of the ply deep - and double thickness wide
    this is glued together with epoxy mixed with cotton flock and cabosil
    i then tape one side with epoxy and two layers of glass tape (50 and 100 wide)
    the oppsite side will get a light sanding with the belt sander and then a 100 tape epoxied on
    keep in mind that the entire boat will get a heavy layer of glass over these joints inside (450gm) and outside (750gm)

    i dont have space in my build area, i already have to open the door to get into the back of the boat, so i just found the stepped joints to be easier than scarfed joints. What i had difficulty with scarfed joints is that because it is at an angle the one board "rides" up on the other board, so it is more difficult to assemble accurately. With a stepped joint you have positive location.

    Hi Colin
    i have been at it flat out since your last visit :D
    i dug up some of the old pics of the "Jarcat" hulls that show the "s" joint and on the other (which is not clear) the scarfed joint where i used dowel pins drilled thru both boards to locate the boards together when gluing.
    The scarfed joints were a hassle, problem is that i first had to "loft" and cut the panels out and then join together.
    If you have BEEEEEEG SPACE you can scarf join the full sheets (8x4=2.44x1.22) together and then do the lofting and cut out the panels same as Mas's cat kinda but i haven't tried so cant really say

    my method is very fast - very simple - very easy and no way does it break on the join

    "i have been at it flat out since your last visit" - Nice to be able to laze around, on your back or side? - (I snore when resting on my back:eek::))

    On a rough passage a VC (Vertical Chunder) is not desirable as the disposal of semi-processed food tends to fall back on one and is effectively spread all over the sleeping space and everywhere else:!::!::eek:

    Colin here are more pics of my chine joints
    what i want to show you is that it is easy to work neat and tidy
    this is what i was trying to tell you the other day
    it is far easier to "sculpt" soft epoxy than to have to sand it afterwards
    the first pic shows the seam after the peel ply was pulled off
    and the second shows the other seams after a very light sanding
    you will also see that my lofting and cutting for most parts are very accurate

    doing seams like this takes time - but its easy light work
    in the evenings i sand down and clean up one seam and lay another approx 6 meters per evening = 2 to 3 hours
    spending that amount of time every evening on your hands and knees is not everybodies idea of fun - but for me its a labour of love :D

    Oh well its been a good weekend, pity its stoooopid Monday tamara sheeeet

    i started on the transom yesterday and got it in today
    my daughter saw me working on another "plank" yesterday and joked about it

    anyway, visible in the top corners are the yellow Kevlar layers that will be part of the "strong" points for the backstays

    starting to look more like a sailboat now :D

    Oh and just a tip for the fella's out there

    i use wax paper that is used in the kitchen for baking purposes over the peelply, it means that your roller never get "tacky" and stays clean and it is MUCH easier to roll out the peelply. I get excellent results and i dont have that roller lifting the peelply sometimes when the eopxy gets tacky

    Can't give you any points yet... Jeeeefffff !.... but I have to admit it is beginning to look like a boat :D Sure it's not a bakkie canoppy just upside down ? :p
