(but even fixed length offers great utility in one's home port).
When you have legs on a boat you don't make assumptions
In an emergency
, if the bottom wasn't flat (and odds are would be somewhere exposed to weather
/ tidal action) then I would probably go for the same approach as no legs. As would be desperate to avoid her breaking a leg (or punching one through the hull - seen that a couple of times).......and then falling over with a splat. Got to remember that these are not additional keels - won't cope with the full boat weight, especially not if being pounded into the seabed - if boat comes down with full weight on one leg as tide arrives or leaves then won't go well.
In practice I don't see adjustable legs being of any value - you would only know how long to adjust them after she had grounded (a few inches before you could take a guess - but no guarantee. You really want to avoid one leg being too short as won't support the boat as a dead weight too many degrees beyond upright).
BTW I've got bilge
keels on mine (in addition to the main keel) - but even with these being far more securely fixed than a leg can ever be I won't want her pounding her the bilge
keels into the seabed.
Some of her sisterships were single
keel, some retrofitted with legs - pic below shows a collapsible leg. Link will show you the height of the boat ashore - unfortunately no pics with legs ftted. As you can see, legs a PITA to stow! and don't discount the weight!

Around here the sea dissapears regularly (twice a day
). We take the same approach as those with less tidal range, by being careful not to accidently run aground
or when pushing things knowing what it is underneath and being able to live with the consequences of misjudgment.
