    I like the hull graphic. :)

    I'd probably have to use an elephant if I applied a graphic.
    Nothing to do with politics.
    A WHITE elephant. Unsalable! :)

    We just got home! Thanks to viking north and Mrs. north for the excellent hospitality and entertainment. Everyone should visit the Halifax region at least once.
    Scunthorp, it was a pleasure to meet you and Mrs. Scunthorp and the same goes on to F and H.
    Now to rest.

    Great, Hoyt & Mrs. Hoyt back safe and sound, was a hoot having "ye all" here, really enjoyed your company and great chats. Lets do it again sometime. My keel bolts will always thank you with the finesse you used exposing them to the darkness of the pre drilled floor timber holes :D . Was a pleasure --Geo. & The Missus

    Permanent Install Of The Skeg Weldament/keel Bolts

    Finally after -- Cutting and stacking 5 cord of firewood for the house, Doing the B&B yearly maintenance, Getting a good start on my house renovation, Getting the lawns and flower/food garden organized, Finalizing project management of three medium sized contracts (boat money), Re setting my dory's mooring anchor, Extracting a saucy raccoon from my neighbours attic, and a thousand more "honey do" items I get back to my project. :D
    Today I mixed a batch of polyester bog and used it to bed down the skeg's weldament /keel bolts. I spread it about a 1/4 in. thick and bolted down the assembly as fast as possible before the mixture hardened. I then torqued all nuts to 50 ft. lbs. I will allow the polyester bedding to harden and shrink over a couple of days and re torque to say 60 lbs. before the next stage of glassing on the skeg shell.

    Skeg Shell Prep.

    On Thur. I filled the blemishes and yesterday did the final touch up sanding on the skeg shell plus drilled the access 3in. cutout holes to allow installation of the ballast. Next I'll cut the ballast access holes in the fin, mark and cut the keel bolt lengths to suit it's contour allowing it to drop down into place. After some consulting with the Designer there is a possibility we might make a slight modification in the ballast install. I am thinking of installing a pre poured lead shoe of somewhere around 1000lbs to the bottom of the fin. Haven't worked out all the details yet but it would require extending the keel bolts to accommodate fastening. Possibly allowing the lead shoe to extend slightly wider than the fin bottom creating a slight Sheel effect. It would also mean more of the lighter(100lb. cu. ft.) stone/resin filler ballast would be required in order to position the dense heavy lead ballast (700lb. cu.ft.)lower down. Thus resulting in a Lower Center of Gravity. The increase of approx. 3 to 4 in. of keel depth as a result of adding the lead shoe is not a problem as far as my boat ramp launch is concerned. Nothing is etched in stone as of yet but certainly dam good food for thought, in other words I'm inclined.---:D

    P.S. I have pretty well cleaned up my outside contracts and finally fought my way into "Honey Do" retirement and my boat work so build activity in theory should increase --

    Is the heavy ballast really needed Viking? My Albin 25s are completely unballasted (except for engine weight) and yet, according to the designer, nearly uncapsizable even with the sails up in a blow.
    Being lighter has advantages, mainly is more easily driven, whether sail or power, translates more economical. Albins designer even suggests locating weight outboard and higher, to ease the uncomfortable snap roll, caused by Albin 25s very stiff righting moment.
    Only mention this because I'm guessing, you don't want to invest more in UNPRECIOUS metal, like lead, than you need to.
    Is there other options to get the necessary stability, other than encumbering the boat with dead weight?
    Or?
    Maybe you have insider information on the future price of lead? Perhaps you aren't planning a lead keel, but a lead vault?

    Yo, the numbers aren't in yet but i'm figuring lead ballast somewhere in the 2500/3000lb range. However if all works out with the lead shoe idea, being lower down it could reduce this by 500lb. or so. Overall displacement is looking like the 10,000 lb range. Other than being as careful and accurate as i can with my numbers on the desired layout, (weights & locations) (which can change upon recommendations), and which I have passed on to Paul (PAR,) I leave it all in his most capable hands :). While I do have a good handle on general boat design, Dam it's great to pass on all that calculating stress to someone qualified and concentrate on what I do best, "hands on". As they say the Devil is in the details and for this foggy impatient old builder i just as soon drive Paul to drink instead of myself, as beer is just too dam expensive here in Canada :D

    P.S. I've got some 4000lb of lead stacked under my drill press, scrounged and bought years ago at 30cents a pound. Latest price here is over $1.00 a pound so I should have enough surplus to pay for the launch party boose or a last minute design change -- can't believe I just said that --change --me ?? Never --Ha Ha

    Just as I suspected!
    And MORE so.
    Not only are you planning to horde lead but you've been doing it for YEARS and more than tripled your money.
    That's what I call REAL LIFE ballast!

    :D

    Ya, Yo, There was a great shortage of diamonds and gold in the scrap yards so I thought what the hell, i can't lose with lead, there will always be a demand for Ballast & Bullets :p

    Prep Work On The Fin

    I bit the bullet this morning and got at that most distasteful job of sanding fiberglass. In order for the encapsulated ballast resin to bond to the inside of the skeg and fin shells the release wax from the molding process must be removed.I gave each a good scrubbing with acetone and a course sanding by hand to roughen up their smooth finish. Six plus hours later this miserable job finally came to an end. In the next couple of days I will mark out the station locations along the fin and use these as a reference to determine the keel bolt heights and also to locate the ballast installation cutouts holes along the bottom .
