Sorry, I was away for the weekend and couldn't answer your comments. Thanks all for great advice.
If I can, I will wait for the slack time. If I have to get out with the strong current, I will test out the suggestions here. So, feedback may be delayed but I will certainly let you know the results.
omatako:
My wife didn't have a chance to maneuver the boat yet. Maybe she will turn out to be natural. All I really need at first for her to get to a level where she can execute what I say promptly. I think we should get out to just practice that.
ccriders:
I don't believe marina would allow a mooring in the fairway. It would be awesome though.
sublime:
I saw the Capt' Jack videos before. But with a 50' boat in a 4 knot cross-current, forces involved are not very easy to manage. Still, I will give it a try next time.
creedence623:
I don't think my wife is strong enough to fend off the boat. It took four guys last time and still we managed to rub against the finger pretty though. Short bursts of forward is a good idea. I am planning to do "exit simulations" so to say. I will not actually get out but only go as far as 1/4 boat length to get a sense of how things are developing.
Yorksailor:
With enough dock hands, we can hold the boat halfway out and go from there without a trouble I agree. And neighbors are always more than happy to help but I feel bad depending on a lot of help. That whole idea of casting off when we feel like it is a little marred.
Tempest & capecodda & HPLou:
I am sure the prop walk is to the starboard. Shaft rotation is CCW. And I am sure my control in reverse is very limited. But I need more exercise to understand just at what conditions I can steer in reverse. Angling to boat in the slip is a good idea and I think it is the best /easiest solution if it works. I didn't think about using the current to gain rudder control. First thing to try.
SVAuspicious:
Prop walk is to starboard, I am sure. At my last exit, I started hard in reverse just as you suggested. Just than I discovered the dock crew didn't untie the midship dock line. Ouch. It all went downhill from there. I feel, if they had done everything according to the plan I suggested, I would have made a successful exit but I learned not to put too much trust on well-meaning dock help. I am trying to explore a method me and my wife can handle at minimal risk.
chris_gee & RhythmDoctor:
If I can get halfway out without contact with the starboard finger, I would be fine as the stern will turn quickly afterwards and bow will be fine since the slip is wide. Boat control is really good in forward so I can quickly escape after that. A common thread here I think is to run the spring lines around the dock, back to the cockpit so I can be in charge. It will adopt that approach after getting some longer, floating lines.
NCC320:
Buddy lines between the pilings could be a good idea but we have a large tidal range here (~10 ft). So it would be a pain to keep them repositioned, tightened. More than that, I haven't seen anybody do that. Probably some marina policy.
imagine2frolic:
I have spent hours looking for docking videos to get ideas. The link is much appreciated.
cesarid:
That's on my mind. I think I am over-propped anyway. Someone in the marina suggested a feathering prop that turns the blades 180 deg in reverse to get better reverse performance. It will all depend on my wallet size at the haul-out time.
