    ". Simple build at around $12,000.00."

    At this price it is impossible to build a boat.
    Or even outfit one if the hull and deck were free.

    Something used , if found in great distress might fit the bill.

    The biggest hassle will be most deep water sail boats are seldom shallow draft.

    Greetings,

    George Buehler claims 45'-0" x 10'-6" "Pilgrim" can be built for $15,000.00. Very similar in size and cost estimates to jubilee. Talking about using HomeDepot lumber, bulk epoxy, treemasts, plywood interior, used sails, homemade winch, welded anchors, galvanized wire rode, latex paint.

    What about the sailplan? Will used triangle sails with line lacing work? Will the T27 sails on freestanding mast work?

    Peace.

    yep - and even though its marketing text he suggests that he wouldn't use it for blue water cruising.

    So again goodwill to all takes the cheapest know example 15k$, ignores that the boat is 5' smaller, price in 12 year old dollars (might want to compare wood and other raw material prices from 1998 and 2010) and still thinks that 12K$ does it.

    And I seriously doubt Pilgrim is quite that good of a boat or quite as easy to build as claimed. (Are there any built?) Regardless - it still looks like 10 times smarter than "jubilee".

    Do you know why the sides even if flat are flared out in Buehler design?

    Must he know?

    12000 is a nice price for a 100000$ boat Goody!

    Build five, sell 4 and have yours for free...............

    I read the displacement goes up faster than the draft when you load it down

    I have asked or hinted at that question several times in this thread and no he does not know why. He still compares his slab sided Jubilee to a flare sided heavy dory. I would put to sea for an ocean crossing in a dory either but at least its likely to stay upright.

    What happened to Noah's Ark proportions in the SOR? That was classic.

    Pierre, see point 4. This should automatically make it to Noahs Ark proportions since apparently this is the most Ocean capable, seaworthy, and seakindly design. :D

    Greetings,

    George Buehler says he over estimated price of $15,000.00 so that it would be good for several years. Pilgrim is very similar in size five feet shorter in length but 2'-3" wider in beam. George wrote that Pilgrim would be a little on the light side for his likes but he would not hesitate to take it on an ocean journey.

    Pilgrim is a dory hull with almost no rocker. The flared sides would make her roll more easier with a slower roll acceleration rate. Reason for Jubilee being long and narrow, it is vertically slab sided, it cant be to wide at beam or to short in length. Something has to compensate for the wide beam at waterline, this is achieved using the stated overall 6-1 dimensions (so it will roll easier). With a generous rocker (even though cross section is flat) that will also help in absorbing full wave impact. Overall hull height is kept low to keep winds effects low as well.

    Like the dory concept but it rides on its ear to much with sails. If going with Pilgrim, would keep all dimensions the same and lengthen it to 63' long. Excellent fuel efficiency, good seakeeping, seaworthy. It would be one of the best modern designs around (eventhough the dory is old).

    The change to full keel on Jubilee seems to be a good idea. Using 3 layers of plywood at sides according to arc plan profile, it would be built on a flat floor.
    Then the hull rocker shape would be cut off. The upswept bottom would also be cutoff but plywood panels cut to bridge the sides. Next step would be to add required rebar and pour solid with concrete. After cure, the keel it self can be moved around and several layers of epoxy added with antifouling.

    It would be turned right side up and the hull bottom can then proceed to be built. Very stable building base and can be kept like that until hull is complete and put in water.

    Question: As mentioned earlier, HISWA builders said that keel bolts were unnecessary with epoxy. Would bolts still be needed or can epoxy bonding of first layer of hull bottom to keel work? There would be an area of about 48 square feet where the keel met the hull bottom, this gives plenty of area to glue as well as distribute loads without causeing stress points. Either way give an explantion for answers. Adding keel bolts into fresh concrete is easy, not having to worry about corrosion would be better if possible.

    You have only good ideas Goody!
    And it is so easy to make a boat just 5 times bigger than the original. Of course that larger boat has a outstanding fuel efficiency and is as seaworthy as one could imagine.
    But at 63ft it will probably cost 16,000 and not only 15,000, let alone 12k.
    And that Pilgrim is a very good design (and has a perfect name for your purpose).

    Build it!

    Two layers of ply should be enough! It is anyway just there to keep the water out. A good quality (Home Depot) interior ply, say 1/4 should do the trick. But paint it inside and out. Looks nicer.

    Good winds, and send a card when you are there!

    Apex.

    Quit putting words in my mouth. Of course a 63' Pilgrim would be substantially more expensive to build. It would have very sleek looking lines (it wouldnt be called fat assed like some boats). Pilgrim is an engine powered boat not sailboat.
    Upon invitation, will visit after Jubilee is built.

    The three (.50" - .75") layers of plywood would be used to to develop the arc shape of the KEEL in plan view, then hold the concrete in as its being poured. It would be basically used as a form. Once the concrete has cured there is no reason to remove the plywood from the keel. The whole keel is then completely encapsulated with fabric and epoxy.

    Keel is positioned flat on the floor and 3" hull bottom is built on top. After that bulkhead frames are assembled and epoxied into routed gaps. From there the 1.5" x 3.5" x 16'-0" stringers are attached to frames every 4.5" O.C. vertically. With final two layers of .375" AC plywood for sheathing.

    Using generous amount of epoxy will secure a watertight boat as well being structurally sound.

    Some basic costs:
    Home Depot lumber $2,000.00
    60-80 Gallon epoxy $2,000.00
    Roll 60" x 375'-0" 6oz. $1,000.00
    15hp Engine $2,000.00
    Tree masts $500.00
    Used sails $1,500.00
    Concrete & rebar $500.00
    Rudder $500.00
    Right angle reduction gear $200.00
