Obviously bigger boats, motor boats, and then up into superyachts and commercial vessels tend to have this problem better thought from the original design as well as having the space to have proper fuel cleaning / polishing capabilities but there isn't a lot available at some type of affordable price when it comes to smaller boats and sailing boats apart from your standard dual Racor setup - but that only cleans the fuel when on it's way to the engine, it doesn't clean the fuel / tanks themselves.
I came across this product called 'Diesel Dipper' from a UK manufacturer. It's a separator / filtration / polishing system for smaller vessels, is reasonably priced (around GBP 1000), small sized (37cm tall - just over a foot), and can be retrofitted to exsiting boats simply by adding an additional full length pick up / suction tube if the tanks don't have a drain at the lowest point.
And that's the crucial important diference - it's designed to suck fuel from the very bottom of your tank(s) where all the water, sludge, etc wants to settle, clean it, and return it to the tank.
Anyway I thought it might be useful for some people here. I'm not connected to the product in any way at all and don't have any experience with it (but lot's of experience with fuel problems, as well as fuel polishing on larger vessels), but I would certainly consider installing one on a future boat.
Of course for the DIY or budget inclined something could be self assembled from parts but it's nice to have an off the shelf solution available for those who want it.
NB: This system is not a replacement for the standard fuel prefilter setup which is normally installed before the engine (eg: commonly a single or dual Racor filter) as well as the on engine filter itself. Instead this is effectively a stand alone fuel / tank cleaner system like a big vessel would have.
NB: If setting up a boat from new (or newly rebuilt) it may be worth looking at the systems from Keenan here: https://shop.keenanfilters.com/collections/all which combine the benefits of the Diesel Dipper and a Dual Racor system. They are quite a step up in price but it may be value if you don't have existing components to utilise / reutilise.
But with the Diesel Dipper you are not using the (expensive) Racor filters as the primary cleaning method like the Keenan system does. Long term, or if you pick up a dirty batch of fuel, that is helpful since you can quickly go through a lot of filters sorting out a problem.
Instead the Diesel Dipper has the water separator baffle / labyrinth in it's enclosed tank (at the rear, drain at the bottom), and a 80 micron (or optionally 40 micron) stainless washable filter. Seems to me that is less / easier / cheaper maintenance wise - and it will then make your actual Racor fuel filter stay cleaner and last longer.
Either way it's still important to pick up from the bottom of the tank for cleaning / polishing purposes.

Nice looking stainless steel construction (not all mild steel like the dual racor units which quickly rust) and the filter is a washable stainless steel model too:
