SBW, in the harbor where Vortex is moored, she's a standout boat among all the other beauties nearby. If you post some pix, make sure to include one of the custom wheel. Amazing.
There's a good chance that adding another division will just dilute the current participation further.
The other possibility is that given the current economic times, a single/doublehand division will bring in some boats who are now on the sidelines. The logistics and expenses of racing shorthanded are much smaller vs. fully crewed.
