Ideally they should but it depends whether you have space. My gas locker can only fit a single cylinder so the spare lives in a different locker and I ensure the cylinder is fully closed. It happily doesn't leak.
If it did leak, then it would probably do so also when connected so wouldn't be...
I don't think they can dredge. But boats going ashore can access the boat yard at high tides. With 1.5m draught, I need a high tide of 4.6m or higher but one can plan around that.
Thornham marina is pretty competitive, but you'd need to check your draught as access is limited. I know that boats up to 1.8m draught can get in and out at high spring tides
Have a look at the Alado - simpler and likely cheaper than pretty much any other system. It ships from Brazil but I have found the company to be very efficient and very supportive. I needed some parts (due to my mistake) and they dispatched them very quickly.
Netherland's Hydrographic Office Tidal stream atlases for Noordzee (HP19) and Waddenzee West (HP17). In near mint condition. Published in 1992 but I doubt the tidal streams have changed much since. £12 for the two including UK postage.
Does anyone know whether/where one can find a deep water mooring on the Exe for a 9.2 meter fin keel sailing boat (draws 1.5 metres)? Likely to be moving to the West Country later this year and my current mooring in Chichester Harbour will be a bit far to travel.
My Ulefone phone is definitely rugged and is sold as such. It's been thrown across the room, dropped in shallow water and is definitely tougher than, for example, the various non-rugged phones that my grandchildren have that are forever suffering broken screens and water damage/destruction...
From an article in today's Guardian. Any thoughts on how something like this could happen? The explanation in the article seems unlikely. The boat in question was a Sunseeker 620 recreational fishing boat.
'Hohnen dropped anchor, made sure everything was secure, and went to sleep next to his...
I think that those types of devices will so rarely be needed that the initial cost plus the effort to remember to keep it charged, possibly for years, without ever using it, means that it cannot be justified.
I bought these via Aliexpress, Took a couple of weeks to arrive but works very well.
