Your calculations do not seem correct.

The stock Habu 32 weighs 7.4 lbs, which is 118 oz. Wing area is 392 sq. in., so that is a loading of 0.30 oz per sq in.

I could not find the exact sq in spec for the PZ Habu wing, but scaling it based on the wingspan difference, it is about 80% of 392, or 314 sq in. Weight is 2.8 lbs, or 45 oz. so the wing loading is .142 oz per sq in.

The ratio is about 2 to 1, not 3 to 1.
