For Offshore races in lower wind forces, up to 22 kts. (F3-F4-F5)
A major difference between 'In-Port' version of VO65 is a use of outriggers for sheeting A3 gennaker. It provides deeper downwind sail angle . MH0 (masthead Code0) is a sail mostly used in very low winds (up to 6 kts), but in this setup it can be used for a wide reaching angles (not very common on In-port races), and as downwind sail when becomes too sharp for A3 gennaker. Upwind legs will be sailed with J1 up to 15 kts and J2 above 15 kts.
This setup is good for races on courses different the strictly upwind-downwind.
