Abstract

A hull form design which incorporates bi-lateral semi-sponsons disposed on either side of a non-stepped V-shaped center hull section. The semi-sponsons extend the entire length of the hull form and comprise protrusions extending away from the center section. The semi-sponsons are delimited by longitudinal steps extending below the hull bottom an equal distance from the centerline on opposite sides of the hull. This design is a hybrid of conventional “V” hulls and catamarans and improves the roll and turn initiation time of convention monohull designs.

First claim

What is claimed is:

1. A vessel hull form, comprising:
a non-stepped V-shaped center section extending along the entire length of said hull form;
two semi-sponsons comprising projections extending away from said center-section and disposed along the length of said hull form on either side of said center section;
said center section and said semi-sponsons each defining a running surface for said hull form; and
wherein said semi-sponsons provide buoyancy and hydrodynamic lift for said hull-form.

2. The vessel hull form of claim 1 , wherein said center section and each of said semi-sponsons are delimited by a longitudinal step extending along the entire length of said hull form.

3. The vessel hull form of claim 2 , said longitudinal steps are disposed at a constant transverse distance from said center section along the entire length of said hull form.

4. The vessel hull form of claim 2 , wherein said longitudinal steps have a height that is at least 5% of the width of said hull form.

5. The vessel hull form of claim 1 , wherein the width of each semi-sponson is at least 10% of the width of said hull form.

6. The vessel hull form of claim 1 , wherein the maximum width of each semi-sponson is maintained for at least 70% of the entire length of said semi-sponson.

7. The vessel hull form of claim 1 , wherein said semi-sponson has a deadrise angle of at most 25 degrees.
