Re: Is there a boat that....
Boats with swim platforms are less likely to meet your PHRF criteria. Are you actually planning to swim from it, or just use it to board the dinghy? The former activity could be dangerous if there are any waves - even just a passing wake- while swimmers are anywhere near the platform. Getting in or out of tenders doesn't require a platform; a fixed or folding ladder will work well for that, providing lots of handholds.
