Re: Bowsprit design
In boats with internal ballast or no ballast or low aspect keels, a low aspect rig allows one to maximise sail area while lowering the centre of effort. The lower centre of effort allows maximum drive while keeping heeling moment under control.
Sometimes you'll see bow sprits on boats with multiple masts (schooners, ketches, yawls) and lower aspect sails (gaffs, lugs, etc.). The combination of bow sprits, multiple masts and low aspect sails together all offer the advantage of maximising sail area while keeping the centre of effort as low as possible, thus keeping the boat on it's feet.
Improving balance is also a factor, both at the design stage, and after. For example, the Mark 1 model of my former boat, the Fantasia 35, was often retrofitted with a bow sprit to correct excessive weather helm.
