structure

Ok so maybe this falls into the composite section but my questions are regarding wood so I'll put them here. I am building a stitch and glue boat of 14 feet in length and about five feet in beam. I built the hull using spreader boards to give the shape desired. I have placed in three frames...

Hello everyone, We’re currently working on a project to install coolant tanks between the section frames on a steel hull sailboat. During leak testing, we discovered small, pinpoint-sized holes in the bulkheads, located above the longitudinal stringers. Does anyone know if these holes serve...

Hi, I'm doing a preliminary weight calculation for a steel motor yacht 24m LOA and I need a some additional benchmark data. Anybody here willing to share weight calculations from their portfolio? Primarily I'm talking about estimating the weight of the main groups (Hull, Superstructure, Engine...

Hi Everyone, I would like to present the tool that I've developped, to assess ISO compliancy of monohull & multihulls, with the ISO12215 standard. 12215 ALIVE ! is a powerfull web app for assessment of Small Crafts with the standard ISO-12215 Design & Scantlings. The standard is translated...

More than 500 interaction events recorded since 2020, 28 damaged ships, three sunken. The spike in aggression towards boats is a recent phenomenon. A female orca called "White Gladis" may have a grudge after being left nearly-dead after the collision with a boat or entrapment during illegal...

Hello Boatdesign.net-ers! To warm up weekend atmosphere a bit I am starting discussion on framing system in small composite pleasure boats. I did quite a research in several books and articles published around, and I am very interested in your opinion, experience and comments on this topic...

Hi altruist, I am a student of Naval Architecture. I am week in hull scantling. I can calculate resistance, desired prop, stability and everything, but when I come in hull scantling stage, I messed up hull scantling. I want to study this from beginning. I need your help. Could you please tell...

Hi all, Wondering if anyone would be able to share any structural midship drawings for offshore supply/support operations vessels. I've done a lot of poking around google and I've found bits and pieces, but nothing really complete. I've asked in here before about a tugboat midship section and...

Hey everyone! I'm new here, but I am working on a design project and have a few questions, mostly surrounding structure. I have done quite a bit of design work, but I'm not as familiar with composite work on small boats. Project background: My project is a 12 m trimaran (LOA == LWL), with a...

Could anyone point me in the right direction on where to find rules for scantling calculations for an aluminum catamaran? Concept is a 15m houseboat! Thanks in advance

hi, does anyone have any tutorial or webinar regarding bentley sacs and moses. i wanted to learn these software for analyzing offshore structure and marine operation. Thanks!

What would the best design be for this material made out of hemp, lime, sand? Thinking trying a Patoon design. Also, remember my Alaska landlord Bob Burgess whom had an amphibious duck in the back yard from the Koren War. Since that Duck was so heavy, could its design be used as hempcrete?

This is my first post here so thanks all for your replies. I currently own a Kestrel 22 approximately 1978 named Falcon which I sail on Coniston, in the South Lake district. My Dad and I picked up this boat 4/5 years ago now relatively cheap and its been a bit of a father son project for us...

Can anybody help me to determine the dimension of Center Girder, Side Girder, and Floors when I have calculated Section modulus Web cross-sectional area?

Hello all, My boat, a 1961 swiftsure 33, needs a complete restoration of the interior, which means I will be changing the layout to better suit my needs. The main bulkheads in the boat are rather displeasing to me because they make the fore and aft sections of the interior feel very small and...
