Moving the Leads Outboard
Alan definitely a good point on the other controls effect on the bubble in the main. Since adding and tuning those controls since that photo I've noticed a definite difference in managing the bubble.
djamied - all the way back at the railing? That seems far back and really wide - notionally that would create a 20 - 25 degree lead angle wouldn't it? Maybe good for downwind but could it point to weather?
I've been comparing boats with similar specs, deck layout, sail size, mast height, beam, and available hardware. A close match - to overall deck layout (performance is slightly different due to the additional weight and the fixed keel) is a Sonar 23. The sail plan is very similar due to the small blade jib and main sail area.
The jib lead location on a sonar is just slightly outboard of where it is on the 216. The angles are very similar, the 216 looks slightly narrower. Based on the keel charateristics, my guess is the 216 will never point as well, hence widening the slot may make good sense.
My conclustion: Moving the leads outboard about 2" from the current block location will create a nice 12 - 15 degree agle. Additionally, this will avoid interference from the rounding cabin profile as well as avoid having to move the spinnaker tack control line and cleat.
Plus you gotta figure since they used a computer model to capture the 216 design approach, theoretically they had a concept of where the jib leads should be for optimal performance - so I'm gunshy of moving them too far outboard at this point until I get more data.
I'll update everyone after I do this and test...
