New Boat!

For ceiling areas I recommend a paint with mould-resistant properties to make it much easier to wipe clean the next season following a winter of condensation.

I did think it would be heavy on the elbow grease . I was worried about sanding the fibreglass but oh well
Guessing I will just get on with it after lockdown
Then it needs antifouling and a new hood 🤬

Personally I don’t sand fibreglass unless I got my hoover attached and full ppe. For the interior it’s not worth it. Just scrape off the loose and go over it with whatever!

You need to sand around all the areas where you have scraped off loose or flaking paint  to make sure that what original coating is left is firmly adhered to the fibreglass. If you don't you'll end up with "blebs" and the new paint will lift off. Then you'll just have to do it all again. 
Do it properly, do it once 

NB- use a 4" sponge roller for a nice finish. Quicker too.

I painted the deck-head/ceiling in Summer 2018...
