505 Setup

     

Team Mast Sails
Wolfgang Hunger (79 kg)
Holger Jess (85 kg)		 Super Spars M2 Bojsen-Moeller OneDesign


This is the set up very successfully used by World Champions Holger Jess / Wolfgang Hunger and several other teams in the 2003, 2004 and 2005 seasons.

 

Mast rigging

Shroud height 4890mm above deck
Trapeze position was 4950mm is now used as exit hole for trapeze barber system 
New trapeze height is 5700mm with tweaker system to release always when wire reaching 
Spi halyard at 5955mm - maximum height  
Spreader length from side of mast to shroud:            
405 in strong conditions           
410 when unsure how to set up for the day half hole out           
415 in light to medium means 1 hole out with end plates; spreader swept back measured shroud/shroud to back of track 150 mm  (using 410mm long spreaders)

Mast should have either a hook in T for the forestay with adjustment through bow section or a 2:1 system with block at above jib. Definitely not a 1:1  direct jib halyard - too much load on box and compression on section

Main halyard 2:1 with thin 2,5 or 3mm rope or halyard lock
