Sometimes the forums can play tricks on you....I'm puzzled that quite often I post something but it doesn't show up....Maybe there are so many embarrassing predictive text errors that it is auto exited out!
Anyway, earlier I posted that it seemed to me that if depth allowed always have foils fully down when manojvering at slow speed. In marinas etc. If anything I would expect that if half up, the hinging centre board of the x would cause the pivot point to be more to stern and also lengthened making it less effective.
Remember that tidal generally trumps wind for causing muckups.
The only exception to this is when you want to make use of shallow draft and allow the whole boat to swing out of pontoon such as when using bow spring followed by reverse pivot method to get off against adverse wind and/or tide.
Generally short bursts of power forward or a stern allow best turning with less directional travel and alternating fore and aft with quick reversing of outboard direction can allow thrust to cancel out and boat to spin on the spot.
Two other useful tips I learned from power boat course are Ferry Gliding , and utilising a gentle side wind to blow boat onto the pontoon ( sometimes small pivot adjustments required).
Always take time to plan it and never wing it. Bravado breaks boats!
Lastly, go slow and don't be afraid to land crew onto pontoon or other boats so they can take lines etc. All decent yachtmen will also want to help , if only to save their boats!
Hope this helps., Roly
