Chine walk speedboat

[Starholk]

Hello. My name is peter and im from sweden. I bought a italian boat Albatro 28 with 2 mercury 250hp. I have full hydraulic steering and also hydraulic jack plate.

Its very unstable and when i hit 70mph .its starts chine walk so much that i loose control. Its like balancing with a bicycle. When i look at other hulls they have alot more strakes. I think that is the problem. I think the boat is coming to high on the water line. From the center of the boat to the strakes its 60cm. I think its in the air when i drive fast. If someone is kind to tell me what to do? I am very good at fiberglass and can do almost everything. I dont just have the right knowledge to know what to do. I want to drive without risking my life in about 85-90 mph. Its not a common boat but they race with this in italy. I have contacted the manufactor but still no answer.

Thanks /peter
