    Thanks all!
    Will add microballons to the shopping list.

    Finished up the last planks/ centerboard gap today.
    Plus lots of planing on the second side.

    Have been sanding & sanding and starting the filling/fairing process.




    Reminds me of spreading Bondo years ago.


    Hard to tell with the contrasting colors but slowly getting quite smooth.
    UPS dropped off 25 yards of 10oz cloth today and 6 more gallons of epoxy due tomorrow.

    Finished up with sanding & fairing and moved onto glassing.


    Went with the 6 oz cloth. Will save the 10 oz for the next boat [ a pseudo-Dragon, plans in hand]



    About 4 hours later.

    And the transom sanded and epoxied too.

    Will the boat have any sort of deadwood/skeg to go along with the centerboard? In the original design, was the rudder mounted on the full keel? What will be your rudder arraingement?

    You're right, original has a rudder post at an angle from rear of cockpit to rear of keel. I plan (term used v. loosely as I've NO plans) on a vertical rudder post at same location at frame 7 which, in theory, will be the end of the waterline.
    I'm thinking of a kick up rudder on a pivot with an elastic cord keeping it down in deeper water.

    Lovingly hand sanded 1/2 the inside with sandpaper wrapped around a pvc pipe; took days and days...
    Oops, wrong picture, not sure how the grinder got there.

    Had fun figuring the position for the cockpit arrangement. Plans call for way too many straight lines.

    Started work on the deck, was a little scared to start cutting into the hull.



    But cut a dozen or so notches out of the sheer; cut 4 saw lines, hammered the bits out with a chisel and smoothed with a file. It all went much easier than expected.



    Steam bent some deck beams; 2 layers of 1.5" by .75"



    Thought i was going to have to do lots of math to figure the ends but ended up just using the cut outs as guides



    Rinse lather repeat....



    Just resting in place at the moment but was happy to get the technique down without much trouble, might add a third layer on top to round up the deck a bit more.

    Question on cockpit plans: when sitting on the cockpit edge when the boat is heeled over; is sitting over the combing better than sitting on a ledge inside the combing? The combing then keeps you from sliding downhill on the slick varnish?

    Coaming are really uncomfortable on the thighs if you are hiking out. I've seen special seeats that cn be moved around that sllot over the coaming and sit on the deck (( a sort of letter "F" profile). I'd have seats inside and provision for sitting on the deck.

    All those armchair boatbuilders who have never actually built a boat but have so much advice will have to abandon their excuses and actually do something if guys like this keep popping up.

    While the boat is looking OK so far, my concern is the design change from ballast keel to centerboard. That's a huge change for one not trained in naval architecture. But, I wish him well.

    Hi from my observations
    i think he will need 150% ballast depending on its position more if inside less if outside. He deep was the full keel and what weight?
    You should be able to approx ballast with keel shoe and add rest internally.
    I would want to make sure you have adequate floors in particular if you have weighted center board or outside ballast.

    So, here's a twist, since this boat is an experiment. If you do not like the performance or initial stability with the centerboard you could modify and add a fin and bulb keel later. It could be mounted on a track so its position could be fine-tuned for the best position down the centerline. Kinda kills the trailer-sailer idea unless there is a hoist near by...

    As a more serious comment, this is a very interesting build and your speed is impressive! This is a thread that many will follow to launch day and want to see how she sails. Then the follow-up of how she gets modified to improve performance. I hope to see those posts in the future.

    Thanks all for the comments and input! I'm sure I've "raised the bar" just by having posted the progress here. I promise to put the first sail videos, good or bad,(bad or disasterous!) up here.
    I'm sure I'll have all sorts of trim issues, I'm really leaning towards a watertight floor with room for ~50 gallons (400 lbs) under it; Not quite sure how to measure the volume without putting a tarp in the bottom and pouring in 50 gallons and marking the level and building the floor there.
    Then use my ~200lbs of steel placed for final trim.

    Or just add hydrofoil wings to the CB and rudder and fly away!

    But first, tomorrow, another glamorous day of sanding....

    Noob question and suggestion:

    1. How do you saw the strips to fit each other? Since they get wrapped in cloth, obviously not going for water tight, but there appears to be some amount of an angle going on there. Do you just set the band saw/table saw to a few degrees and rip all forty-leven strips the same? Different per strip, same full length? Lay on the preceding strip and run a pencil down it?

    B. For the goopy hands, and for the future adventures you will have, how bout a gopro or some other sort of camera, set to time lapse on the work space? I'd love to see one on the Ideas shed, and might have to consider doing a kickstarter to get them one. Because they don't take enough pictures already...

    Hi! On my prior kayaks I bead/ coved the edges but here they are all cut square. I envisioned plane-ing them to fit but with lots of bar clamp use I only ended up needing to plane the aft ends of the planks at the bottom twisty corners of the transom.
    I had a gopro for track days but it was last seen in the Bahamas while scuba diving, probably has some excellent shark and crab selfies on it now.

    Had you used the bead/cove method, do you think it would have resulted in less time spent fairing?

    I hate fairing BTW. :-)

    At Sebring, 8 hours of unlimited track time (3 fillups and $200 in brake pads later...)

    And since disaster footage is funnier... going thru a turn ass end first at 90ish.

    I don't think so, the planks go thru up to 90 degrees of twist during their run that I don't believe the bead / coving would have hid that any more than what i did.

    i'll absolutely reinforce my molds on the next one to allow better clamping of the twisted areas while the epoxy dries which will reduce the fairing / sanding time.


    also my other 'disaster' footage (and not just because i had to video a tv playing a dvd recording that i could never get my computer to open) they were not in the same year...

    Should be my motto, or a tattoo...

    Finished interior sanding and laid out the cloth.



    Then spent this afternoon spreading ~a gallon of epoxy. Thanks to whomever I stole the small foam roller idea from, doing the vertical areas would have been much harder without that.

    Seen drilled rotors do that, but not solid ones. Good thing it didn't lock the wheel up.
