Not talking about boats in freshwater, this is wind turbines in the seas.
I can't answer your specific question.
North of me, on the West side of I-35, just South of HWY-82, in Gainesville, Texas, is a holding facility for wind turbine blades.
I've walked the facility, and have 'gotten inside' the individual blades. They're hollow for awhile, near the blade 'root.'
The wall section is enormously thick fiberglass reinforced epoxy. They weigh tons, and I don't know how they could possibly be lighter than the sea water they would displace, if placed in the ocean.

A GOOGLE search brought up a G.E. Vernova-built Haliade-X wind turbine, in the Vineyard Wind 1, offshore farm, of which, one of its 107-meter blades broke off, 20-meters from it's root, with small fragments washing up on Martha's Vineyard. I suppose that the 'large' pieces sank.
The material on the beach was described as green or white 'foamboard'. Some photos do show traces of fiberglass bonded to some of the foam debris, so it appears that 'unadulterated' fiberglass is not buoyant in sea water.
