This was on the underside of a blue plastic barrel used as a yacht racing mark in Strangford Lough. Any idea what the long grey tubes are? I didn't notice them at the time and so didn't check them out - it's always possible that they're bungees!

...these are but one of them has a bryozoan sea mat on it.

grey tubes

I wondered if they might be old Forest Kelp/Cuvie (Laminaria hyperborea) stipes, which are a long cylindrical shape, that have lost there fronds and partly decomposed. There is no sign of the holdfast but that may be just out of shot.
