Where in the original post does it say I have an issue with people using fleet ships? My issue is WHY they are using them, they are using them because they have unlimited chain and for no their reason. And again my issue is not with any "significant damage" they can do to my hull, that's not the issue, the issue is with the CHAIN.
This is NOT about not being able to run away as you seem to think, it's about the manoeuvrability side of it.
For example, Dave is tagged on the way into port by Bruce with his fleets ships (lets just say Endymions for this example) and Bruce starts the battle by ordering his fleet ships to "demast". He then fires his own chain at Dave but he manages to angle his sails to avoid a good portion of it but still loses maybe 5% but then you have 3 other ships all fire their chain and they're firing 24s so even each of them only manage to connect with 2 or 3 shots each, well that's 6-9 24 pounders passing through Dave's sails. So that could easily be another 5-10 percent. So Dave is already down to maybe 85% sails at which point most ships have noticeably reduced manoeuvrability. But he battles on, by this point Bruce is firing ball so Dave is now focusing on angling those shots while also trying to position himself to effectively return fire. BUT the whole time the AI is shooting their unlimited chain taking off 5-10% sails every minute or so, and before Dave knows it, he is down below 60% sails and decides he better repair sails now because he is doing 8knts and can barely turn his ship to angle shots or get off his own. Problem is that the AI still has chain and is still firing it and still only needing 2 or 3 shots each to connect and Dave will be extremely lucky if his sails ever get repaired above 70% and is never going to match Bruce's manoeuvrability or even the fleet ships for that matter. And there's very little point in Dave targeting Bruce's sails because he only has 4 broadsides of chain and Bruce can just retreat and repair them.
And this is assuming Bruce doesn't have other players inside the ports waiting to join the battle.
This is ONLY possible because those fleets ships are not subject to the same restrictions as the players and that's why players have started using them.
THAT'S my issue.
