Propeller slip and its role to the boat’s performance
Propeller slip and its role to the boat’s performance
By Thomas P.

Facing one of the best well-designed ribs which is indeed characterized by its fast hull, and two of the best-designed propellers it was impossible to resist the temptation.
We tested the Hydromotive 15 ½" x 19" (lab finished) and the Eco Enertia 16" x 17" in a Technohull SEADNA 999 on the transom of which a Verado 350hp was mounted.

The purpose of this test was not, of course, the comparison of the two propellers, which have absolutely nothing in common between them.

We just wanted to see the behavior of the above combination rib - engine when it is working with two such different propellers.
