Hi, my boat Awara a parker 235 sits on a pontoon at the moment but will be birthed back where the level of the lake is shallow. It would mean I would get the boat out and in with the keel up under motor. It is based on lake windermere so the biggest waves will be from the Ferry. My question is about the stability of the boat when keel up for the purpose of birthing the boat? Can anyone give advice? Would it be safe or should I always have the keel down even under motor?
