    One finds a rich benefactor. 75'+ boats chew into the finances at an alarming rate.
    :p

    PAR Yacht Designer/Builder

    Vallen, considering the ideas you have and your vessel requirements, do you really think looking around discussion forums and performing minimum Google searches, will really yield you a suitable design? Plans for a 75' - 100' vessel will cost many thousands of dollars and this is simply the beginning of the budget. How many designers do you think are offering free or low cost plans to 75'+ vessels?

    If it's a model to play with, well there's plenty to select from, though don't expect much by way of modern design. If it's an actual vessel, maybe you'd be best to hire someone that actually can contact the appropriate sources, for a vessel of this class and contract the appropriate firms, that can either develop one or offer a set of modified plans, from their stock design drawer, as you seem quite ill equipped to handle this type of venture. This isn't intended as an insult, but simply an observation, based on previous inquiries here and your seeming understanding, of what might be involved in a project like this.

    As to modifying or scaling up a set of plans, well in a word, don't. If you have to ask why this isn't such a good idea, then you're decidedly not the person that should be performing this task.

    Vallen, it would be important to know the type of boat you want to design. Even considering everything he says PAR, if someone wanted to help, he would need to know what boat you have in mind.

    I spent 5 hours looking up boat designs. Im not looking for designs that I can follow to the letterIm not a marine engineer thats why Im asking you guys about this ive should of been more clear so ill out line my mission statement to be more precise

    Im am looking for plans that could be hevily modified for a 75' to 100' boat with a home built engine as well if i make a 75' boat how wide and deep/tall would be optimal

    As side note how thick would you make a pvc layered hull would you make this material is strong cheap an easily fixed when applied corectly i was thinking 2 3" thick layers woul be usable

    I would love to design it myself but I would need to know more about larger boats first

    Bruce Roberts has plans for some big stuff,not that I'd ever think of doing anything like this.


    Look on yachtworld,go to advanced search and search for bigger boats,at whatever price range you want to spend.

    You need to build some smaller boats first to build up your skills.

    As the size increases, required money and time increase exponentially. A 75' to 100' boat requires a well organized crew to finish unless you plan to work on it for 10 years or more.

    You also need to spend time on as many similar boats as possible before beginning the process.

    Buy a used yacht first. You can almost always buy used for much less than building new. Spend a couple years becoming very familiar with the best features of the boats close to what you want and accumulating enough wealth to consider a new boat. Maintaining it is something in itself you have to work out.

    When you know exactly what you want, and when you are sure you can't get it from any existing boat, then consider building new.

    Modifying plans to that extent will cost you as much as a custom design. Not following the plans makes them useless and a waste of your money. Plans don't scale up or down much without completely re-engineering them. It is a physical principle you can't get around. You can get stock plans with a customized interior for less than $20,000. That will include a reasonable amount of technical support once you start the build. Considering that a boat that size will cost over a million dollar (assuming you don't have any fancy finish) saving a tiny amount of money makes no sense.

    Vallen, a boat of 75' or 100' may be too large or too small depending on, for example, the number of passengers you want to have on board. On the other hand, the fun aboard a boat can be of many types: sunbathing and bathing, water skiing, dine in the light of the wonderful moon is in your country, play roulette and black jack in a luxurious casino, ... Passengers, are they going to sleep on board ?, each one take snacks and drinks from home or purchase them on board ?, you need air conditioning or fans are sold on the boat ?, etc etc.
    Each of these possibilities can lead to totally different vessels, even with the same length. I mean, if you do not give us more details I do not think anyone is able to help.

    If you have that much income, it would benefit you greatly to hire a writer. Your posts come of as amateurish and careless. Proper language, particularly when written, conveys an image of who you are.
