    proatest ....

    as the name says > see .... http://blog.proadesign.com

    is a test boat for a 3x bigger one >
    already started .... but ???

    see .... http://www.proagenesis.org .... the picture >>>> ” in “

    actually ...
    I never thought of having it at this size for real >
    but since it workes so great ....

    we even made it available by smallboats ... by the late don elliot
    as a building booklet production ... the shorter > vfp 25 !

    since there was the limit of 25’

    here is some data on both >

    loa 31’ 9.5m loa 93’ 28.5m
    boa 12’ 3.6m boa 36’ 11m
    hvf +7’ 2.1m + 16’ ~ 5m
    total 19’ 5.7m total 52’ 16m

    bowl 20” 50cm wl 4’9” 1.5m
    bodeck 24” 60cm deck 5’9” 1.8m
    draft 10” 25cm draft 30” 75cm
    draft hvf ~ 3’ 90cm hvf 7’ 2.1m
    mast 20’ 6m height 60’ 18m

    the hvf on the 3x will be most likely
    of a more compact geo metry ... then on the test proa !
    because of the stress expected ... and because we dont need
    the scale draft of 9’ on this recreation yacht !

    but contrary to a dagger board .... is striking ground >
    not that big of a catastrophe with the hinged vector fin >
    because the boat doesnt have to come to a hold !
    but will just circle around the hvf tip itself !

    head room ~ 32” 80cm ~ 6’ 1.8m
    up to 42” 105cm ~ 7’ 2.1m

    the head room for the proatest is unter the entrance hood
    if you plan on useing it as a regular boat >

    this could be increased >
    by increasing the freeboard of the hull ... some 6” - 10 ” !
    and on the 3x up to .... 1’

    bunks 2x 7’ 2.1m long up to 12x 8’ ... 2.4m long possible

    dsp 800# 350kg dsp 10 ton

    the float now is a shorter 12’ loa ... 3.6m loa > 1/2 build of the main hull !
    the float of the 3x will be around a 1/3 section >
    of the main hull only .... ~ 24’ ... ~ 7m loa

    sa main ~ 70f² ~ 6m² sa main ~ 600f² ~ 50m²
    roller jib ~ 25f² ~ 2m² roller jib ~ 200f² ~ 20m²
    ww sail ~ 25f² ~ 2m² ww sail ~ 200f² ~ 20m²
    stay sail ~ 50f² ~ 4m² stay sail ~ 450f² ~ 40m²

    sail area is not yet final !
    so far .... there is no reefing > but a storm main sail used
    used with out the roller jib > just the wind ward sail can be !

    the stay sail is on a roller .... too >
    but can be made on a halyard as well !
    since only used in lite winds ..... when there is time ....

    steering through 2x rudder on the side of the main hull
    independant control > mostly the rear one used >
    the front only on changing directions and emergencies !

    through foot sleeves below the cockpit !
    through hand lines on the 3x ?

    see http://www.proatech.org ... rudders etc for more on this .....

    the side the rudders are on >
    can be decided as for the use required
    right now they are on the wind ward side by proatest >

    because on beaching side ways > they are protected then !
    and since the vfp had the fin under the float >
    it was higher on the wind ward side then ....

    on the hvfp now > they may be better on the lee ward ?
    since this type heels a lot more more .... when steering may be ??
    and it is lower on the wind ward side when beaching ....

    you would have to hold them up ....
    when sliding side ways onto a beach though !

    the side they will be on the 3x could be the opposite as well !
    because rudder control is easier > if on the lee ward ....

    the steering effect is not that much .... different !
    actually we could use 4 rudders > one on each side ......


    this project started out as being 61’ loa !
    the tiny 1/24 model > 2’6” loa > you can see on
    http://www.proatech.org > videos !

    then I saw the effects of lenghtening > and it became longer ....
    if I had anticipated this > and being all left to myself now >

    I may have just made a 2x being 62’ loa 24’ boa dsp unter 3tons
    just sitting head room .... more I wouldnt need for myself !

    but now all the frames are done > and the center section finished !
    so its to late for that ! the shortest it could be made now >
    is 72’loa > but the steering is a lot better ... with being longer !

    even though at this size > the speed potential will not be reached
    that often .... and the waves are much smaler for ....

    the big boat !

    I'm very interested in the principle but both your web site and this piece is so poorly written I'm finding it hard to even understand the point you're trying to make. Please ask someone who is a little more conversant with English Grammar to write it for you.

    ..... here we go again !

    if you are not interested in having a discussion about the vfp >
    then I would suggest .... you leave this tread .....

    because I will not have any one coming here >
    and complying to your wish .... and having him ....
    as well insulted > since this is abviously your only aspiration !

    as they say > love it or leave it .....

    but any one ........
    is invited to asking any technical or scientific question .....
    any time !

    regards proagenesis

    Was so sorry to see Bruce Foil thread closed, though I understand the necessity. The vector foil is a subject I find most intriguing. Mans' technical pursuits on water probably predate the use of fire! Hopefully we can see this thread and subject matter blossom and grow without issues. Thanks to all for the sharing of ideas for the betterment of our sailing! Just a thought from a newbie here today..........

    " how are you doing ? "

    herself > " on the planet of the apes ! "

    but she was all wrong >
    this isnt the planet of the apes !

    its not even the planet of the stupid apes
    or the planet of the so stupid apes >
    not even realizing their own stupidity !

    its the planet of the united stupid apes
    being so conceited ... competingly >

    they are just not even thinking about
    being any thing else .... but so stupid ³ !

    Perhaps genius and mental illness combined in some cases
    to necessitate drastic measures....
    Would be a guess that this thread already needs moderating....
    I personally was hoping for a better result...C'est la vie
