I added 2 extra lift handles on all the kayaks. On the Revo & AI; 1 behind the seat, the other in front of center hatch.
On the Oasis, 1 behind the front seat, the other in front of hatch in front of rear seat. (Be sure to use s/s nuts, bolts and fender washers) These spots seems to give the best balance when lifting solo.
When loading onto the Hullavator, I wheel the cart (w/kayak on it) along side of lowered Hullavator arms, lift by the aforementioned handles so kayak sides rest on Hullavator arms. Wheels just drop out when kayak's lifted. In the 'hull side down' method the kayak will stay on it's side on the arms, so it's easy to put on tie down straps without having to hold kayak in place. I've found when putting kayak on 'hull side up', kayak had to be held in place while straps were put on.
When unloading kayak, lower Hullavator arms, undo straps, insert cart into scupper holes and engage the cart post pin so cart stays in place. I then rotate top side of kayak towards me, exposing installed handles and lift kayak off arms.
I've also modified the Hullavator (thanks Wayne!), by drilling a hole to insert the pins into to keep the handles in the "squeezed position". This makes it a lot easier to lift/lower the kayak without having to have your hands on the handles. Remove the pins when Hullavator is in down position, so when kayak is taken off, arms stay down. Otherwise, they will swing back up real quick when weight of kayak is removed! ( I've learned that the hard way a few times! lol) This simple mod has made the Hullavator a lot easy to use, especially for the heavier Oasis and if your bars are far apart. http://kfa-ny.org/forum/showthread.php? ... dification
