I would get the gps now and have it with me at all times with good batterys, Practice using it on the car ride up to the boat.just in case Make sure the VHF works and take your cell phone. Try to work the loran and programme in the correct GRI for your area. The loran usually works if an antennae is connected. Not many moving parts inside. Should things start to suck all at once, you now have many tools in which to call for aide, with your correct location(very important!)Since you have the internet at your disposal, Look for info on correct radio procedure and owners manuals on the old Equipment in the manufacturers archives. Wear your PFDs in unfamilar waters. big time saver. I always write the word "Shark" on my console to save time while under water. I know im not going to have time to then write it if i see one.
