No its not the self tacker that has been left off ( no good to a single hander and this boat certainly doesn't have the volume to be anything other than a single hander ) but something far more unfashionable.

I left the bow vertical unlike the very now fashionable raked back " wave piercing " bow that we now see on most F16 designs. At the time of building the hulls I had been breaking the Sprit wires at the front due to a very high and long angle back to the forestay that the early Stealths came with ( the later ones have the mounting point much lower down on the inside of the hull). Tremendous pressure was obviously being placed on these wires and by consequence the hulls. Proof of this was one of the Stealths at the club was showing deformation of the hull just in front of the beam. To overcome this I moved my Stealth's sprit wires as far foward on the bow as possible to get much better upward angles and thus less tension from the Spinny. Using the same diameter D12 I haven't had any break since.

Now we can either rake the bow back, put a lot of carbon and reinforcing in the hull to take the increased loading or we can move the mounting point as far foward as possible by leaving the bow almost vertical, I choose the latter as unless you are doing about 30 knots the true wave piercing bows simply do not work. I do understand why we narrow down the top part of the hull but it has nothing to do with wave piercing.

Would I do the same if I was building another boat, nah raked back bows just look so much more ubber cool
