I also like braided, something like New England Ropes double braided. I would suggest a pair of 25' lines for port/starboard bow lines, and a pair of 15' lines for stern, with an additional 25' backup line for towing/rescue/emergency situations, which could be something less expensive. I use 1/2" which is probably overkill. I prefer having the bow/stern in different colors so you can direct guest crew in lay language ("grab the white rope and get ready to step onto the dock"). I also like having the spliced eye live on the bow/stern cleat to which it is used, with some sort of easy, dedicated mid-ship attachment for the other end. This could be an additional cleat mounted on a vertical bulkhead, a dedicated cam cleat, a padeye for a snap, etc. Set this up to suit your most common docking use. You will get great joy out of devising systems which are as simple, practical, functional, and intuitive as possible; use your boat a bit before drilling any holes. I also favor having fenders semi-permanently attached or quickly and easily attachable to dedicated points, preferably not to cleats in such a way as to crowd the cleat with multiple lines. An example on your boat might be: install a robust padeye (with interior backing) on the exterior cabin side wall above your engine control. Then install a clip on the whip of your midship fender so the fender hangs at the proper mooring height. (2 clips if you commonly use 2 dock heights). On approach, you can deploy the midship fender through your sliding window by clicking the snap to the padeye. Many variations and only one rule: have fun customizing your boat! Regards, Mike.
