    Hi TimGoz,

    1. I never uses any full size templates, tempting as it may, but always loft my hull and deck frames.

    2. The hull get pulled of the jig and a temporary stay fitted to keep the hull sides from collapsing inwards - see photo above. Then the deck beams and deck stringers are installed and the beam sheer takes shape.

    3. On my TT24 I fitted an 8hp inboard marine diesel (see photo) and easily moves the hull to max displacement speed of about 6 knots and maintains it even in a blow - Port Elizabeth, S. Africa and it is notorious for it's winds.

    However, if you looked closely, you will notice that this TT24 has no full keel but a fin. This is a modification I done after hull number one and was for the better. She points better, light on tiller and actually tracks like a train on rails.
    I regret selling my TT24 at the time and she has done a circumnavigation with her current owner since.

    Feels like building one for myself again......:confused:

    Waynand,

    Even though Roberts says "Do Not Loft" the boat from the offsets, but to use the full sized patterns, I was very skeptical. All the reading & research I've done gives the opposite recommendation, as do you. My machinist's mentality & the fact the "patterns" are now over 15yrs. old dictate lofting also.

    My offsets table included with the plans was never printed clearly. One & a half decades later it is hard to make out. Hopefully he could supply me another.
