Re: Folding prop help
As has been pointed out by others, and worth reiterating: Consider how you will use the boat.
If you want to race, and have the money, get a folding prop as discussed. No-brainer.
If you are cruising/weekend sailing, consider a fixed prop - for a boat your size, a 3-blade. Fixed props are significantly cheaper (there is a big used market), easier to maintain, less likely to go wrong if you are miles offshore. Arguably more robust. Arguably better for reversing - although much depends on the folder brand.
Folding/feathering props are more expensive, benefit from maintenance (e.g. annual removal, cleaning, reassembly), more likely to go wrong - BUT you'll probably get 0.5knot more speed, and they tend to be quieter (although fixed props people often leave the engine in reverse - no noise, more drag).
