Thanks for your added interest, Steve. No, I have drained from both bungs and the inner one was completely dry, even with the boat tilted at a fair angle. I did consider the trim tabs but, having checked these, find them to be as before. The intriguing thing is that Stingray has been performing perfectly for months now with the tabs fitted and goes up onto the plane effortlessly. It wasn't just the once though, I tried several times when we moved positions and the same thing happened. I think this is going to take more investigation. The thing I can't understand is, nothing has changed; if I'd taken a big biffa as crew, fine, but I didn't. I'm sure it is probably the tabs, upon reflection, but, why now?
Terry.
