It takes some work but you can do it. Make sure you wrap the hull points up the nose or it will explode easily on landing.
You can also look at the MAW Walrus which also has gear.
You also need to play with the
Static Compression
Max/Static Compression Ratio
Damping Ratio
For each contact point
0.51, 2.5, 0.65 Float tip out of the water
0.2, 2.5, 0.65 Front water point
1.21, 2.5, 0.25 Middle Water point
0.4, 2.5, 0.65 Aft water point
Once you get these in you'll need to adjust the vertical of the contact points to get it to float right. Make sure the front out of the water point is much higher than the front water point and makes less than a 45 deg angle from that point.
