Wot's a capsize/knockdown? How far over do I have to go before I can claim to have had one?

the pontoon has space for dinghies - i'm thinking we probably need to upgrade the dinghy, is there a sensible self draining option? (it could be 2-3 weeks between use) Is self-draining a thing outside racing dinghies? Wouldn’t worry – stored on end or upside down on land. Maybe get some rain...

Don't stress it. Go by your own experience - if it ain't broke....

LNTM on Osborne Bay VNAZ. Why does seagrass zoom in on anchorages - can't it find somewhere else to grow?

Where do boats go? Surely hundreds or thousands are bought new each year, but only a handful scrapped according to the news.

I saw that. Horribly coincident with that Baltimore bridge thing. Wouldn't fancy relying on one form of propulsion, but guess it's quite normal. What happens in commercial ships? Things like system redundancy to reduce chances of power loss to an absolute minimum I guess.

Pegasus 800 anybody?

Hi Refueler I was just quoting ‘GHA’ from further up the thread. As mentioned in previous post, when I was writing the post, with the quote, I could see the image. As soon as I posted, the image changed to red cross. Seems like the picture is on IMGUR: So not sure what’s going on here...

Yes, that's the one RivalRedwing, only mine's the blue box one with the simulated paddle pulse output. They certainly don’t make it easy Refueler! Changing to the NASA transducer had to replace hull fitting of course, chissling away rock hard sealant on the old one. Now it’s just a case of...

That's odd. Picture has disappeared again now I've posted the reply :(

Do we know what happens at a standstill - would the speed trace still give an indication of whether the transducer’s working or not? Guessing the pulses get further and further apart ‘til were at a steady DC. Would we be expecting a steady High, so a steady Low indicates a fault? Am working...

Thanks for warning. Bad wording on my part - was talking about the cable from interface box to instrument head, rather than interface box to transducer cable. NASA manuals terrible - comes with the budget price I guess. Raymarine the other way - take you about 5 weeks reading one of their...
