Having just moved from sail to power and gone through this exercise, I concur with Pete's advice. Removed everything to identify it, clean it and decide whether to keep it. Only then did new stuff come on board. We have a clubhouse where members can 'gift or recycle' their stuff which sometimes make it easier to offload still useful items. Good luck and welcome.
