A few things that you might consider adding to the boat

Barber Hauler
Cascading Backstay
Harken J/27 Deck Layout (requires access to the J27 Yahoo! group website)
Replacement Bowlight - Perko Bi-color light 170-BB-DP1
Replacement Threaded Stud (for Forestay or Lowers) - Navtech D320-S12 (available from Rig-Rite or Defender) - -S10 is probably the right size for the others
