In my time I used to sail into and out of the lagoon on Culstra and park on the beach .
Happy days . Nip over to Olhao under sail for the supermarket and Fado, market and fish , sail back again on one tide ?
I gather that the lagoon has been wired off for years now, people abiding it with cluttered mab flotilla
Was a fab place but a bit bouncy on the sand on a NE at hw springs
No crappy catamarans anymore on the beach. Its all cleared and civilised. The village is legalised. A school, library, sports ground. Paved main Street.

Saying "weed" is about like saying "rock." There are all kinds, and anchors react differently.
  • Scattered eel grass. Good anchors can set fast and dig. Plows take too long to set... but the Excel (looks like a plow but is not) sets fast and is non-clogging, so it does well. The weed inhibits deep setting, but the bottom is usually acceptably firm.
  • Tight root mat. No anchor can burry because the shank will hang up. You snag the mat and holding is determined by root tenasity. I doubt any anchor would reset with a mat skewwered on the tip (common on the Chesapeake). A sharp toe seems to be the main thing. The problem is you can't tell if you have a good big mat, or just enough to hold the power set. Hope the wind does not shift, because you don't know how you are hooked. A bit like rock slabs with seams and potholes.
  • Kelp. A little like cobbles; a bigger anchor can reach through. Like eel grass, it must set fast. And once you drag, most anchors will clog. Again, holding is often determined by root tenacity.
