We have owned a Fleming 55 and 65. We basically live on our 65. The 65 any day is better mainly due to space but also the extra displacement makes a huge difference to performance at sea. If you have instagram check @Freja_f65
So for Pirates Cove I thought there would be enough water on a 5 foot plus tide if you followed the black line. I thought you'd be okay with depth and the issue may be width. Isn't there a rocky shelf by the green marker? I could see a risk of kissing a stabilizer fin on what I remember as a shelf or ledge that was very close to the channel or in the channel.
That would be impressive to see an 80 footer enter Prideaux, local knowledge is king.
There are many other similar limiting scenarios at other small anchorages.
Put simply, large boats may not be able to anchor at small anchorages or in close proximity to other boats.
I will extend this further. With the exception of the Bahamas where anchoring at all sizes is very popular, there is a general practical presumption that larger boats will tend toward marinas. Moorings are not generally available and anchorages are limited. Plus larger boats have more people aboard often and they want to access land. There are some major long distance cruisers with large boats who do regularly anchor, but if you look at ratios of anchoring and mooring balls vs. marinas and docks, you'll see the larger boats moving toward marinas. I saw this in the PNW and have seen it in New England. The one place the opposite occurs is Eastern Canada, specifically Nova Scotia and New Brunswick, where small boats are at the marinas and larger boats are very limited in some areas.
I would caution and agree for those who like to anchor in certain areas, a larger boat will force adjustment to marinas or different anchorages.
That's an interesting observation. I'd expect the opposite in many areas, as larger boats will often be self-sufficient for longer periods of time, can carry bigger dinghies for shore runs, etc.
