Interesting thoughts. I sometimes think the yard should hold back on producing yet more designs, such as the canoes they are working on, and concentrate on building the market for their existing models and working on their general quality assurance.
Having said that, one of the attractions of Swallow boats is that you can order them with all sorts of customisations to suit your own wishes. You can have a ketch rig, lug rig, sloop rig or even junk rig. On my own boat, I could have had her with one, two or no quarter berths. I would think that the main market for Swallow boats is men of a certain age who want an enjoyable boat for general fast sailing, often short handed, which they can afford to buy new for cash, and they like the idea that it can be tweaked to exactly what they want. For example, some of the BREs have fixed plank bow sprits, others don't like that. Whether this variety will have a detrimental effect on second-hand values over the years is a valid point. At the moment, every water ballasted Swallow boat that has come onto the market that I know of, seems to have sold very quickly.
