7.50 Metre Diesel Launch Design #280

Here’s a large handsome launch laid out for relaxed cruises in sheltered water.  The commission came from tropical waters hence the open layout and sun awning.  Diesel power in the range 15-25Hp will be plenty for economical running at a speed of 5knots.  Construction drawings show strip and glass construction over laminated frames for simplicity and low maintenance.  The keel carries an outside lead casting of 200KG to set the boat down and give a steady feel.  Inside ballast may be used as an alternative.  This is a hull that would lend itself to other arrangements – with an enclosed wheelhouse it would make a delightful small cruiser.

The drawings are in metric units.
