V-bottom planing hull design

Hello guys ! Im new here and im looking for help at the design of a 24' planing hull.

The idea is a semi-oceanic boat with a deadrise arrown 10 and 15 degrees with a deep V at the bow.

If someone have some plans to start drawing or some information i will verry grateful !!

To be more especific, the craft im designing is a Aluminum Landing Craft.

i leave a image of the craft i want to modificate to a hull more "marine" with a deadrise of 20 al the transom. and a V shape at the Bow.

I will suggest you to have a high value of deadrise over 20 degrees to have more dynamic stability in rough wave condition . I know that increase the roll and fuel consumption but i believe that is important if you want a good seakeeping in Ocean.

I disagree with the need for high deadrise, unless this boat has a high top speed goal in it's SOR. You have to sacrifice quite a bit with 20+ degrees of deadrise, which is only tolerable on certain and specific SOR targets.

A 24' near coastal cruiser, with occasional romps in deep water designs abound and about every design firm has some to select from. Check with Glen-L.com, Bateau.com and the other usual sources.



This is one of mine and well proven.

NicoARG, as you can see, everyone, trying to help, tries to show the boat from his portfolio that believes best fits your needs. So it would be very important to you to do a better description of what you're looking for.

rwatson, you have progressed a lot with your 3D models. Congratulations.

rwatson, I have some skills in sheet metal work. Very keen on your 28 feet planing hull design. Visually, your design makes an excellent statement. I would like to execute it in steel. What stage are you at right now?

Please be a little more specific about what you mean when you say" Landing craft"

In the usual parlance, a landing craft is a boat that is a cargo carrier or troop carrier capable of powering up onto a beach while retaining the ability to get itself off the beach unassisted. A deep vee is questionable for such a purpose.

See picture in post #1. That's exactly a "landing craft", imho. A deep vee is questionable for such a purpose, so vee cant be deep.

Specmar does these using a vee bow section and then cutting the tip of the vee off aft to form a zero deadrise pad.
