I think the best option really is a sidewind jack. The reason is the fit depends on the tube diameter of your current jack and how it mounts. I couldn't quite tell the dimensions of the round tube from your photos, or how your jack is attached. It looks like it may be bolted or use U-bolts and doesn't have the standard 3 x 3 mounting pattern, which means you may have to weld on a replacement.

If your current jack has a 2" outer tube and 1-3/4" inner tube the best A-frame option is the A-Frame Trailer Jack # DL22530 with Wheel # DL22414. This has a finish designed specifically to resist corrosion that is more durable than zinc so overall it's the best for A-frames.

That said, the best option for a boat trailer for use in salt water really is a side-frame mounted jack from Fulton, the Fulton Bolt-Thru Swivel Marine Jack # FXP15L.

It will bolt right onto 3" x 3", 3" x 4", or 3" x 5" trailer frames so is easy to use. It is the best jack for salt water though due to its Z-Max 600 finish, which means it has been tested to withstand 600 hours of saltwater spray.
