ORIGINAL: <SNIP>... having Jib trim does make the boat go a bit faster. It does take a 3 or 4 channel radio.
I'd have to interpret that the real intention here to be that the skipper's skilfully trimming the jib
MAKES the boat go faster while having jib trim
ALLOWS THE SKIPPER to do that skillful trimming... so my question:
As the skipper, how do you trim the jib properly? My guess would be to allow it to default to a neutral setting and then adjust from there, judging the goodness of the trim from sail set and speed change? (This is essentially what I do when I'm physically ON a boat.) Can one effectively observe those things from the shore? Or are there other indicators or even other techniques used?
