The lady has a grassy bottom......

......but very few barnacles.
(I did think of putting a grassy a*** - but thought that a tad rude)
It all came off very easily though with the high pressure water hose.
It also showed all antifoulings are not the same, the bilge keels were painted in Interspeed Ultra (pretty expensive stuff) which is hard and there was no grass and no barnacles.
The hull was in Flag Cruiser (still pricy but half the price of Ultra) and despite being soft and ablative (erodes away in the water) the grass grew just fine.
A difficult decision for next spring.
