We might be different to some crews in the respect that when I am crewing, I have control of the main and jib sheet. We have experimented with Alex controlling the jib, but it is much easier for him to worry about steering and t-foil. This may partly be due to the location of the jib cleat. It is on the floor behind the daggerboard case, but is a bit of a pain to adjust even though the cleat platform is angled up and has a wedge riser block.
I always let the jib out for the bearaway but in some respects, hoisting is actually easier with the jib in tight as there is less friction of the kite against the jib. In some windy and busy mark rounding circumstances it might be required for me to bin the hoist half way, jump on the wire to save the boat, then run back in and finish hoisting before getting back and out. In these situations it is very good to have the jib eased as luffing up to avoid a windward boat or a slow mover would be a wet experience.
