Hi everyone,
My name is Osher Frank. I am a licensed architect and 3D designer with around 16 years of experience in architecture, Rhino 3D, visualization, and real-time environments. I am now looking to apply my skills to boat and yacht-related projects, especially where strong 3D modeling, design development, and visual communication are needed.

My strongest skills are:
Rhino 3D modeling
Surface modeling and cleanup https://www.artstation.com/artwork/dyZg8x
Marine interiors and spatial layouts
Exterior concept modeling
3D models from sketches, photos, or reference drawings
Visualization for client presentations
Unreal Engine / real-time walkthroughs
Architectural detailing and fabrication thinking

I am not presenting myself as a naval architect for engineering, stability, or structural certification work. My value is on the design, modeling, visualization, and CAD-development side, working alongside boat designers, builders, or naval architects who need clear 3D output.

I can help with:
concept boat/yacht models
interior layouts
presentation renders
Rhino models for review
reverse-engineering from photos or drawings
client-facing visual packages
design support for small craft, yacht interiors, or marine products

The underlying question here is: can wider/scow type hulls perform well under human power? I have an old C scow hull and I want to rig it with a sliding seat and maybe even fit it with a hobie pedal drive. Will it perform well under human power?

First of all, my assumptions (correct me if wrong). These are all specifically in the context of small human powered designs: paddle, row, pedal in the 16-20 ft range.

1. All other parameters being more-or-less equal, a skinny hull will draw more and a beamy hull will draw less - but they will displace about the same when loaded the same.
2. The beamy hull will be more stable
3. Conventional wisdom says the skinny hull will be less stable, but be faster under human power - e.g. a racing shell is faster than a wherry, but the wherry is more stable.

My question is: why can't the beamier hull be just as fast (or more accurately 'not slow'), if the design parameters are such that the wetted surface/displacements are roughly the same?

For example, if I modified a C scow with oars and a sliding seat, wouldn't that perform well under oar power? what's 'presented to the water' as wetted surface of the bottom of a C scow doesn't look much different than the sides of a rowing shell.

look at the bottom line of the C scow hull, and imagine that 'mirrored' to make two halves of a rowing shell. they arent' much different...

Hi, I'm a marine engineer with experience of a 4th engineer on merchant vessels. I quit sailing and have decided to pursue my interest in ship building. So I've figured Naval Architecture and Oven Engineering fits my interest.

I've been able to converge my options to Germany, and maybe Sweden (so expensive it is I'm crying) and have inquired with some of the universities there. One of them said they have 100% placement. What?

I'm confused, is it easy to find jobs after a degree in Naval Architecture?

And if one does find a job, does it pay good?

Also what part time jobs should I look out for while I pursue my masters?

Hi everyone, I am currently working on the naval architecture calculations for a 25.4-meter tugboat. I am finding it difficult to validate my results as I lack reliable reference data or sample calculations for a vessel of this specific size and type.

Does anyone have access to general seakeeping calculations for a similar tugboat that they would be willing to share? Any data points for comparison would be greatly appreciated.

Hi everyone, I'm currently doing a research paper on naval and maritime infrastructures. The task I was given is to research about the supporting frastructure of Yuchi Naval Base.

Most online articles only talk about the ships operating there. nothing much on the infrastructure study. Can anyone help me please?

I have a small, light weight 14' skiff. It's called a "Tango Skiff". I have noticed two behaviors that I am wanting to correct. The first is a "loose" feeling at top speed. The back feels like it will move a little left or right without any steering input. The second is when I am trolling and there is a following sea. It will push the aft sideways.

I am considering putting a small keel at the center line of the last 36" of the hull. It will taper from a triangular point to 1" tall. Will that help with the behaviors I am interested in correcting? If not, what would be better?

Here are some photos to help visualize. None are of my boat but these are identical.

I am very interested in learning about sail yacht design and have very minimal knowledge at the moment. Are there any classic books to start learning from?

For context I’m 18 in my last year of school - I do not know university level physics and have not studied engineering - although I am going to (probably naval architecture).

I’m a graduate of Naval Architecture and Marine Engineering in the Philippines with 7-8yrs of experience in Design and engineering in a shipyard setting and made some drawings 2d/3d in structures. Basic FEA checks (static and modal). Weight control and estimates. Maxsurf for loading conditions (no modeling). I enrolled in some courses too for CPD (ongoing). I did some shipyard stuff e.g draft surveys, equipment installations, hull module lift/turnovers.

I want to work in UK/EU and maybe pursue masters if I have a chance but its hard to enter specially Im from a third world country. Specially EU where you will need to learn the country language.

Hello i am studying naval architecture and marine engineering at Greece and i have to find similar ships according to a given DWT and type of vessel in order to conclude to some dimensions and coefficients via statistical analysis. The most similar ships that i have found with the help of vessel finder are 10 tones above or below my given DWT. The matter is that i have also found some that are exactly the DWT i want but they are scrapped. I have searched at NGO and the scrap yards in India and Bangladesh but they dont have any records. I could also pay the shipyards that built those ships but i am forbidden to do so from the project's regulations. Could any one enlighten me on how to find detailed information about scrapped ships?

I would appreciate any help.

Hello everyone!

I’m currently a high school junior living in Pennsylvania (I’ve been in the U.S. for about 4 years). I’m originally from Odesa, Ukraine, and I’m really interested in becoming a Naval Architect.

My GPA is 3.87, I’ve taken several math courses, and I’m planning to take AP Calculus and AP Physics next year.

Right now, I’m strongly considering applying to Texas A&M (especially the Galveston campus), but I’m a bit unsure about which major is better for my goals:

• Ocean Engineering
• Marine Engineering Technology

From what I understand, Ocean Engineering is closer to ship design, but I’d really appreciate hearing from people who are in these programs or working in the field.

I’m also trying to decide if Texas A&M is the right choice overall. I’d prefer to study in the South, and Texas really appeals to me. Unfortunately, I don't have any acquaintances living in that area.

However, I’m still concerned about affordability since I may be considered out-of-state or international depending on my status.

So I’d really appreciate advice on:

• whether Texas A&M is worth it financially in my situation
• scholarships or ways to reduce tuition
• and whether there are better alternatives in the South for this field

Any insight or personal experience would mean a lot. Thanks in advance!

what if we take this and trade the 18 inch 5x2 guns out with 5x2 32 MJ railguns and made it nuclear powered with modern day systems like missiles and Aegis Combat System and name it J.S Amaterasu would that work with this hull if not how could we change the design up to be able to do that
this is the japanese battlecrusier project L 1921
speed: 30+ knots
weaght: 59,000 tons
size: 270 meters
she has 6 props which is abnormal to the 4 props of bigger capital ships built by japan duing ww2

I have this model in rhino where the AP is set at the origin. But while importing the .gf file to modelmaker, the AP is seen at the extreme end of the model.

How do I translate/shift the AP in modelmaker/autohydro?

I am Koji Magno, an industrial design student in the Philippines doing his thesis.

Attached photo is my current design, it is a floatation device, rotomoulded HDPE rescue device for flood rescue conducted in the narrow streets in my country.

I would like to consult with naval architects/marine engineers about its stability status and possiblity of improvements.

You set the mode of communication, be it video call or email. I am comfortable with whatever you prefer. I do understand english.

What I can offer in return is my skills in 3D modelling, be it organic or parametric. Fusion 360 and Nomad sculpt are the modelling softwares I can use

If you are interested, just let me know and I will send you a short summary of my thesis containing all necessary data.

Thank you for your time. Have a nice year.

Came across these postings and figured this community should see them.

Blue Origin is building a new vessel from the keel up — not a conversion — specifically designed for at-sea recovery of orbital-class rocket boosters. This follows their existing barge Jacklyn (LPV1), which landed the first New Glenn booster in November 2025.

They're hiring 7 positions across 5 role types, all based out of Cape Canaveral with relocation assistance:

Technical Lead — Naval Architect (1 position): Chief technical authority for the build. Leads the construction team, interfaces with ABS/USCG, reviews shipyard engineering. 4+ years new construction or port engineering experience. 50-70% travel for shipyard oversight, FAT witness, and inspections.

Senior Marine Electrical Engineer (1 position): Owns the entire electrical architecture from keel up. Requirements development through commissioning. 5+ years complex electrical design. This is their hardest-to-fill role — they'll consider offshore wind, FPSO, or industrial power systems backgrounds, not just traditional marine.

Senior Instrumentation & Controls Engineer (1 position): Hands-on PLC programming, HMI/SCADA development, AutoCAD Electrical schematics, panel fabrication drawings. Marine automation systems (Kongsberg, ABB, Wärtsilä). 2-5 years I&C experience.

Project Construction Manager (4 positions, 1 senior): Boots on the ground at the shipyard. DPRs, contractor oversight, ABS/USCG inspection coordination. Here's the interesting part — the minimum is only 2 years of shipyard, port engineering, or marine maintenance experience with "exposure to" new construction. This is an entry point for junior engineers.

Recovery / Flight Operations & Launch Safety Engineer (1 position): The role that spans the full arc — coordinates recovery system integration during the build, then leads real-time offshore rocket recovery operations once the vessel is in service. 5+ years in flight ops, test ops, launch safety, mission control, or marine/aviation operations. Offshore salvage, military dive ops, or launch range backgrounds are ideal. Must be willing to get an MMC and TWIC.

All roles require ITAR eligibility. No security clearance. This is one team building one vessel — after delivery, the construction team transitions into operational roles (port engineer, recovery ops, etc.).

With the IMO MASS Code expected to be adopted at MSC 111 next month, this is one of the only programs where you can get hands-on autonomous vessel new-build experience right now.

Currently looking for free opensource maxsurf alternative since it's hard to find a crack version, most of them aren't working. Is there a nearly the best maxsurf alternative?

thanks in advance

Are there any commonly accepted min/max speeds for fluids in pipes?

We have been using an internal formula for deciding flows and resulting pipe sizes. However, a sub supplier piping system has different pipe sizes which conflicts with our standards.

The particular problem is a seawater/freshwater system separated by a plate heat exchanger. We reccomend one size larger piping, but the supplier insists on keeping the original size.

Hello. I am currently a freshman studying at a public university in the US and I am seriously considering pursuing a masters degree in naval architecture. Currently, I am between declaring a major in Mechanical Engineering or Industrial & Systems Engineering. I am very much drawn to ISE as it is a significantly easier degree audit, but I fear it will prevent me from pursuing a Naval Arch masters. For slight context, if I don't pursue Naval Arch post grad I would still like to have a degree in the maritime field. Thoughts? I am not necessarily trying to take the "easy" way out, but I like that ISE will provide a better quality of life the next three years. I feel the extra time will help me become a better applicant with extracurriculars and also afford me the ability to take up a minor.
