A GOOD drinking water purification unit; shovel (for digging anchor pits); at least 2 good anchors, and plenty of good rope. Sounds like a big load - do you have access to a small (8-10 ft) inflatable?? Our 9 ft Mercury has a 1000+ pound load rating. Towing lighter stuff in it would give you more room in the boat for gas and gear. Could stash some gas along the way - strategically - for the return trip?? SAFETY first!!!
