Well I decided to go with 5,and that seems ok for me.I can
just make out the bow of the boat and feel happy that its quite realistic.
I also found out the length of the IXC was about 76m,so 3-5 seems a good number.
Sorry,I know we discussed this earlier in another post somewhere,I guess it happens a lot in here,going over 'old ground' ...Oh well
Thanks
