Yeah, I suspect you were hitting the lock a bit hard. The width is what it is. Ships like MS Alina are made to just fit. A bit like Panamax ships are made for the Panama canal.
Most likely you saw the ship oscillate after the initial collision and things got worse after that. I didn't think it was possible anymore to get into the situation you were in. I have some ideas to improve that.
And yes, I will change the anchor system so you can get back to your last Anchorage.
