Can anyone tell me what the blue line is called and how to determine the angle of it?

Is it specific the the type of hull the boat has?

Thanks again in advance.

Got it. It is the forefoot.

The stem or the bow. The forefoot is the lower part of the bow.

The stem angle can not be easily changed without it affecting the development of the hull panels and/or the frame shapes. Curious if you just wanted a structure defined, or if you prefer one angle over another, and might be thinking of changing the angle on a preferred design. :)

ks8,

I like the performance description of the NV23 and the look of the hull but 23ft but is bigger than I am looking for.

Ideally I would like a 19ft-21ft Novi with the pilot house/cabin like the P19:

However I do not know if it is possible so I am just doing as much reading (learning) as possible :)

You can scale down the Novi23. The superstructure designs have flexibility on most designs (but not all - such as the Pangas and LB22 needing to be kept very light), as long as you honor the frame locations. This is general info that is repeated all around on various subject posts on the forum. In general, most plans can be scaled 10 % up or down safely without structural changes being necessary. More than that 10% requires some dialogue with the designer. Typically the safest scaling will be to apply a scaling multiplier in all three dimensions (easiest with a metric set of plans), which will maintain the development of the curved panels. Scaling only one dimension, such as length, can sometimes get very tricky, depending on the curves and angles. I don't want to put words in Jacques mouth, but he has essentially communicated in the past that he will only do a new development of panels for such non-3D scalings, based on the time he has to do so, and the fee to basically custom redesign a whole new boat. It is an involved time consuming process to do it properly professional, and has a fee associated with it. For some that is not an obstacle, but consider that in deciding whether or not to scale in all three dimensions, or just one or two. :)

Once you settle on a design and approach, if you haven't already, it might be advisable to post a new thread directed at the designer (Jacques) to clarify exactly what he will approve, or tell you to avoid, or outright prohibit because of safety issues. When the boat is complete, it will be *your* boat, and you are responsible for it, but it is wonderful to have the approval of the designer of the original backing your modifications to that original. And certainly, take us all along for the ride during the build, with some pictures and commentary, if you like. :D

The DE23 has the same hull. It might be easier to scale those plans and then shorten the cabin to the P19 size. :wink:

ks8 and gk108,

Thank you both so much for your responses in getting me pointed in the right direction.
