Balancing the boat exactly on the axle is key. My hobie 18 it was directly under the shrouds. on some boats (my mystere 5.5) the best spot for the wheels is actually between the front beam and the shroud.

if you have lots of water in your hulls... this doesn’t help.

make sure you have either lowered your sails.. or the wind direction is helping you.

one person on each front hull pulling on the bows/bridal and get up some speed to climb up any little hills/beach.
