Power and Sailing Yacht Plans List Copyright 2023 Michael Kasten Updated April  2023 This page provides a list of our currently available boat plans, a link to the web page for each design, and a price for each design.  What Do Plans Cost..? Below is a list of prices for each plans package that we offer. The first group lists our Sailing Yacht Designs and the second group lists our Power Yacht Designs .  Some designs are COMPLETED and others are INCOMPLETE.      COMPLETED STOCK DESIGNS :  The Estimating Plans and Building Plans prices given below in BOLD BLACK TYPE are for a FULLY COMPLETED STOCK DESIGN , the plans for which can be shipped immediately on receipt of your order.   Please see our Stock Design web page for a description of what is included, and how our prices have been determined.    INCOMPLETE OR 'SEMI-STOCK' DESIGNS :   Prices given below in PLAIN TEXT indicate plans that are INCOMPLETE.  WHY , you may ask, have I even bothered to list INCOMPLETE designs below...? Since people's circumstances often change, it is inevitable that some boat design projects will be abandoned before they are finished, and in some cases after considerable work has been done.  This can occur as is so well described in the first few pages of Rockwell Kent’s excellent non-fiction sea story, “North by East” , or as the result of a change of fortune, failing health, or for a myriad of other reasons. A few of the INCOMPLETE designs listed below (not very many) have been developed on my own, in other words, with myself as the 'client'.  Others have been created at the behest of an individual client to explore an idea or a concept.  Either way, I believe all of the designs listed below have merit.  We offer these INCOMPLETE designs at a substantial discount versus what it would cost to develop an entirely CUSTOM design, the difference being that the 'discovery' phase of the design process has already been accomplished.  Even so, there is still quite a bit of WORK REMAINING in order to complete the Plans Packages for those INCOMPLETE designs.  The prices given below reflect our actual cost to complete the Estimating Plans or the Building Plans Package for each design, assuming there will be no changes to the design as it is presented.  If you take umbrage with the cost of our INCOMPLETE designs, I urge you to read our Learning Yacht Design web page.  If one of the designs below is "close" to what you have in mind but you would like to tweak it some, I will be pleased to provide a detailed estimate for any revisions you have in mind.  If any of these designs is of interest, please inquire .    CUSTOM YACHT DESIGN :  A new CUSTOM design will necessarily include the process of " discovery " which represents Stage I of the design process, during which all options are on the table including size, type, configuration, layout, rig, materials, etc.  By comparison, given that many of the INCOMPLETE designs listed below have already had a considerable amount of design work done, very roughly the cost to create a CUSTOM design can be on the order of some 20% to 50% greater than the prices listed for the INCOMPLETE designs below, in order to accommodate the "discovery" process on the way to achieving a completed set of Building Plans.  Is the added cost worth it...?   Yes , we believe so. Please see our article on Custom Yacht Design for our best answer to that question, where you will also find an overview of the design process itself.  Our Design Stream article additionally describes how we use CAD to best advantage throughout the design process. If a new Custom Yacht Design is of interest, please inquire for more information.    COMPLETED NC CUTTING FILES :  There are several designs below for which NC Cutting files are ALREADY DEVELOPED , in which case the price is in BOLD BLACK TYPE .    DEVELOPING NEW NC CUTTING FILES :  All other NC Cutting File prices are listed in PLAIN TEXT, and reflect our actual cost to develop NC Cutting Files for that design from scratch, in which case they can be developed for metric or imperial dimensioned materials as needed. Please see our CAD Design Stream article for more information about our NC development process.    ORDERING INFORMATION : All prices are given in US Dollars and are subject to change at any time.  To place an order, please see our contact information below. To order by fax or by mail, a PDF Order Form has been provided for your convenience.    What's Included...? Estimating Plans - Building Plans - NC Cut Files... ESTIMATING PLANS :  Since all the basic information about each of our designs is available here at our web site, and for free, we no longer offer basic Study Plans.   Instead, we offer a much more useful and complete Estimating Plans for each of the designs listed below. Our Estimating Plans include the following: Drawings:    Sail Plan / Exterior Profile Drawing Interior Profile & Arrangement Drawing (one to four sheets, depending on vessel size) Structure Drawings (one or two additional sheets, depending on vessel size)    Documents:    Drawings & Documents List Written Vessel Specification Detailed Equipment List Structural Scantling List Laminate Schedule (if needed) Structure Weight & Surface Areas Builder Short List appropriate to the specific design Cover Letters to Builders re: scope of project, etc.    Our Estimating Plans are useful for study, planning, commentary, or mark-ups in the event you want to consider variations on the layout or the rig.  Primarily though, the Estimating Plans are intended for Cost Estimating .   Considering the price lists given below, the Estimating Plans represent an outstanding bargain and include quite a lot of useful information. Our Designer's Cover Letter serves as an introduction to the builder and outlines the scope of our involvement.  Our Owner's Cover Letter is a template which you can modify as needed in order to provide an introduction to the builder; to outline your intended build timing; and to let them know what stage of completion you intend their quotation to cover. NOTE :  Estimating Plans do not contain sufficient detail for actual construction of the vessel.  However the Estimating Plans do provide enough information so that builders can provide a firm quotation for construction, and to allow a preliminary construction contract to be negotiated.    BUILDING PLANS : Prior to your construction contract being finalized, and in order to actually build the boat, the complete Building Plans will be required.  Our Building Plans include all the contents of our Estimating Plans as listed above, plus all the remaining detail drawings required for construction, including the following: Drawings:    Lines Drawing Offsets (if not CNC cut) Structural Sections Joinery Sections Joinery Details Construction Details (Several Sheets Including Hull & Deck Fittings; Ports; Doors; etc.) Spar Plans (Sail: Several Sheets Including Spar Dimensions; Spar Fitting Details; etc.) Machinery Plans (Power:  Several Sheets as Needed) Numerous Detail Drawings as Needed       Vessel Design Data, including:    Hydrostatics & Trim Stability Compliance Report Performance Analysis Hull Data for Propeller Calcs Endurance & Range Under Power    Building Plans also include a thorough review of and revision of the Equipment List and Vessel Specification in order to suit your specific equipment preferences. If the drawings or documents require further revision for your use, for example to make changes to the layout or the rig, we'll be pleased to provide an estimate for making those revisions. Please see our Stock Plans page for more information about what's included, and how we can customize a stock design to suit your requests.    CUSTOM DESIGN : We can modify any of our Stock Designs to suit a newly defined purpose, or we can work with you to create an entirely new design based on your requests. Please feel free to inquire about any modifications you may have in mind, or about creating a new Custom Design to suit your specific requirements.  In way of inspiration we have provided quite a variety of Prototype Designs , any one of which can be modified as needed to create a fully completed yacht design.    NC CUTTING FILES : Several of the Stock Designs listed below for construction in metal have already been developed for automated NC cutting of the metal parts. "NC" simply means 'Numerically Controlled' - a technology for creating pre-cut boat parts directly from the 3D design model. For details regarding the benefits of NC Cutting and to find out what's included with an NC Cutting File Package , check out our article on Our CAD Design Stream and the articles linked from there.    MORE INFO :  Please see our Site Map to quickly find any of our designs, to peruse our portfolio, and to find our articles on a variety of boat related topics.  

What Will the Boat Cost..?

This is the most difficult question of all, and one for which I do not have a ready answer.  However it is a question that ultimately does have an answer...!   For any meaningful cost discovery it is necessary to solicit actual quotations for construction from a short list of qualified builders. 

For that purpose, we offer completed ESTIMATING PLANS for several of the designs listed below, with their prices listed in BOLD BLACK TEXT .  For any designs listed below that are INCOMPLETE, we have also provided the cost to develop ESTIMATING PLANS for that design, the prices for which are given in PLAIN TEXT.

Please see the following articles for information about boat costs, and about the process of soliciting estimates from builders:

• The cost given above to complete the Building Plans for an as-yet INCOMPLETE design includes the cost to develop Estimating Plans for that design.  
• If you first arrange for completion of as-yet INCOMPLETE Estimating Plans, the subsequent cost to develop Building Plans for that design will be reduced by the full cost of having developed the Estimating Plans for that design.  In other words, the INCOMPLETE Building Plans prices given above already include the cost to develop the Estimating Plans.  
• For ALL orders, if an already completed set of STOCK NC Cutting Files are ordered along with an already completed set of STOCK Building Plans for that vessel ( both paid for in full at the same time ) we will provide a discount of 10% off your entire order.  And... this discount may be applied in addition to either of the above discount options..! Note however that this does not apply to any of our designs for which the NC Cutting Files or the Design itself remain INCOMPLETE.

IMPORTANT DESIGN NOTES

GRP or PLYWOOD : Any of our Aluminum or Steel designs can be converted for construction in GRP or cold moulded plywood. The cost of any such revisions will be quoted separately. For more information, please inquire .

STEEL : Any Steel vessel can easily be re-specified with an aluminum structure. To convert a stock steel design to aluminum, please add 20% to the cost of the Estimating Plans or the Building Plans for that design.  Conversion of NC Cutting Files from steel to aluminum will however require a completely new set of NC cutting files, for which please inquire for an estimate.

* ALUMINUM : The Aluminum vessels listed above can only be built in steel if the design is extensively modified for that purpose in order to accommodate the added weight of the structure. For more information, please inquire .  Conversion from aluminum to steel will also require a completely new set of NC cutting files, for which please inquire for an estimate.

** WOOD : Please note that our large Wooden Vessel plans are generally priced higher, since revisions will nearly always be required in order to accommodate the differing wood species that will be available for construction, and the consequent differences in scantlings and overall weight. Those revisions (within reason) are included in the prices indicated above.

*** NC CUTTING FILES : Although a complete Building Plans set is required in order build any of these boat designs, the NC Cutting Files are entirely optional . In other words, the Building Plans are required , even if you purchase the NC Cutting Files for that design. The cost of NC Cutting Files is in addition to the cost of the Building Plans. Please see above for discount options that are available...

The NC Cutting Files shown above with prices given in BOLD BLACK TYPE have already been developed , in which case they will have been created for either metric or imperial dimensioned materials, and for either steel or aluminum (noted in parentheses).

If the vessel will be built in a location that requires changing the measurement system , and / or if there is a change from steel to aluminum or aluminum to stee l structure, then additional work will be required, the cost of which will be quoted separately and in addition to the above prices. Should such changes to any of our designs be of interest, please inquire for an estimate.   

YACHT TENDERS

Our aluminum yacht tenders are the perfect companion to any of the yachts described above.

8' to 14' Prams - Building Plans: $250 . NC Cutting Files: $250 . (The Building Plans are required. The NC Cutting File is optional. The cost of the NC Cutting file includes interacting with the cutter of your choice to assure compliance with their cutting equipment.)  

PROTOTYPE YACHT PLANS

If you don't see a design here that suits your requirements, please see our Prototypes web page for links to other designs that are either under development, or that may offer a few possible ideas in way of inspiration...

Preliminary study sketches may be available for some of our Prototype Designs. If you would like to know more about one of them, please inquire .  

NACA Foil Shaped Low Drag Aluminum Paravanes

Please see our Roll Attenuation article for more information on Paravanes for Motor Yachts.

These low-drag paravanes are balanced and are adjustable for different speeds. They make use of NACA foil shaped surfaces combined with a lead ballasted NACA foil shaped bulb. They are designed to be machined out of marine grade aluminum plate and rod so that they can be shaped, and so they are lighter for a given wing area than steel paravanes would be.

The sizes given above are conservatively rated. In other words each size can be used on a larger vessel than is indicated. It is all a matter of degree. The roll attenuation will simply be more or it will be less, as compared to that of a larger or smaller wing area.

Paravane effectiveness is a function of wing area and pole length vs. your vessel’s righting moment. With a larger the vessel the poles can be made longer, achieving greater leverage, therefore a greater effect for the same size paravane.  If you have an existing vessel on which you would like to install these paravanes, but you don't have a paravane rig, we can provide a design for the rig that will fit your boat.

For more information, please inquire .
