From twin based power to twin catamaran
, under power, no problem. They behave very similarly. Not enough difference to unnerve you. The most challenging part, under power, is docking
. But I am guessing you already are comfortable with that.
Under sail, have you had any sailing experience? If you have, no worries then. If you have not, I'd suggest sailing with someone that does. They can show you the ropes! (yes, that was supposed to be a VERY bad pun. We all know there are no ropes aboard ships!) Other than that, you just have to remember to reduce sail just when you're getting to decent speeds (First reef at 25 kts or so).
44 foot, okay. 66 foot! Big boat! But that's only psychology and the fact you need to react sooner cause every thing takes longer. Some slightly different rules cause you're over 13 meters, but that's mostly equipment
