Drawings for a 16ft motor launch

Motor launch drawings from an old book

These lines and construction drawings for a stylish motor launch come from a pre-WW II copy of the MotorBoat Manual. After all these years I trust no-one will be offended that I photographed them and made them available, and hope that others will find them as interesting as I do – the alternative, I guess, is that they become forgotten.

The forward section is fairly traditional and the central section seems conventional enough – but the aft half of the boat goes somewhere a little different, with styling that seems to me to have been borrowed from much faster boats meant to hydroplane. Yet this is a displacement hull with a small 3-4hp engine, and so I’d guess that the tumblehome in the stern is simply a matter of fashion, and that makes her a period piece.

I love the claim that this boat can be built by amateurs – I know some who could, but I fear most of us, myself included, would be well advised to steer clear of it for fear of wasting a lot of expensive timber!

  1. is ti possible to get a copy of the plans of this motor launch. i am doing a project in college and these plans would be perfect, regards julian

  2. Hi Gavin,

    would it be possible to get a clearer picture of the lines drawing on page 35? especially the measurements around the stem area on the profile plan? They’re somewhat important, as they give the grid size for the table of offsets… (I’d like to loft this boat as an exercise) If you have it, a higher resolution of p32 would also be great.

    Thanks, kind regards,
    sb
