In my opinion, high q loading coils are a much better loading method
than linear wires. FWIW, full sized 30m elements are pretty manageable
and it's quite easy to homebrew a rotating dipole. The issue with salt
spray, at least in Aruba, is the dissimilar metal corrosion between
stainless steel and aluminum. Unfortunately this is difficult to
avoid. Perhaps covering the connections with a non-acidic caulk helps.

I have a12 year old Force12 30M linearly loaded dipole. It works fine
when the local sea air doesn’t cause the loading wire connections to
corrode making the antenna unusable. I’m tried of needing to repair
the antenna every few years!
I’m considering a JK301 that uses loading coils and should be much
more reliable. If someone has any experience with this antenna, I
would appreciate any comments. The JK Antenna website doesn’t show
any access to the assembly manual that I would like to see before any
purchase. I have made a request for the manual from JK Antenna but so
far no response.
Thanks es 73,
