Tony-Being on CSC a few days a year
and afflicted with Fellowships referenced disease. IMHO, the Potter era (I have a 23SF)was better quality controlled, post Potter was quality with extra weight/materials(dad's 18 is a tank). After 1987, the boats were lightened up(I had one), but I think were built well with poor quality hardware. As for a Potter 23SF value-$4-$8K for a boat in need of a transom and/or deck with an older motor but may run well. $8K-$12K is either a steal or someones headache. A single motor 23SF above $12K should be solid. Decent 23SF's with a twin set-up starts at $15K-18K. Anything above 18K will have newer power and records of the work done which as you have seen goes in to the $40K area. That is how I have seen it since 2002........
