Easyway out

HI. I'm building a globtrotting heavy desplacment sailer. My Question: I do not have any "Building plans", try to use common sense... BUT!!! About stabillity and waterline, sailplan and so. Can you help me to calculate this??? or do I need to contact a "know how" person?!
here's a tread: http://www.boatdesign.net/forums/metal-boat-building/boat-building-progress-31503.html#post344900

 

Yes you are going to need a designer to work out all the details.

 

evantica please believe me - you need a NA to help you
you will save a fortune by getting the help from an expert
i design and study design for myself as a hobby, it is a very steep learning curve that really takes a lot of time and passion
dont go it alone - get a local qualified guy to help you
your project is NOT STANDARD

 

Evantica - think about resale value if you don't have a professionally approved design specification- its not worth it, protect yourself.

 

Thanks for advise friends. Yes! I'm going to consult an expert!

 

You are building a boat without experience or plans and say you are using commong sense? That is an oxymoron.

 

Gonzo. I never sead I build without experience! (read what i wrote!) I'm a welder since many years. And constructed quite a few things = I belive in my self! BUT... I don't have any "drawings/buildingplans" on this voyager I'm creating right now.
And all the "matematics" Stability, rigging plans, waterline eg. I'm not able too. so I've asked you on this forum... What I call common sense!

 

I don't know much about this type of boat looking at the picture here http://www.boatdesign.net/forums/metal-boat-building/boat-building-progress-31503.html#post346166 I'm curious how the weight compares between the steel new copy you have so far and the wooden original?

It seems from the structure on up you'll be building something entirely new that can't be copied from the original due to the material change -- it makes sense to calculate twice and weld once... even if you're putting in your skilled labor for free building it, if you can optimize material use you can end up with a better boat and offset the cost of professional calculation there. I'm not sure about the timetable though as you've already got so much hull constructed... I do admire your courageous spirit. I've had good times experimenting with small skiffs. I've learned as much from getting things wrong as when they turned out perfect the first time; probably more. But can you afford to chock this up as a learning experience if it goes wrong? On paper, it's easy to give it another go if the initial calculations are amiss; in real life not so easy. A forum such as this is great for getting ideas on overall concepts or some specific questions. But you have real money at stake here. Spending some money for solid labor to work out a solid and complete plan is cheap insurance against what you could lose if things went wrong. Paying to get a NA working on your side would be the way to go in my book on a project of this size.

 

Hi Obsseion, listening to what you say. And you're absolutely right! I have contacted a "Know how" person. And He'll come and do the exact necessary measurement. And he have great confidence in my little project...(thank God). So I see not that much worries. Yes. this is an entire new boat and have nothing to do with the ol' Wooden one, beside been a plug! I've been into boating for many years, I believe I can see what going to "be" and "not". But as some of you mention there is too much at "stake" (?) Coz' this vessel is going to take me around the globe and have to be safe... Thanks for concern friends. And anymore useful aspects will be appreciated!

 

Have to know!

The More I read many of the treads, the more curious I get!
We leave my "allreadygoing vessel" out of it! Coz. It's going to be perfect in time!
Lets say: " I build a hull that floats, just by studying other sailboathulls" by using common sense (hey Gonzo) Then I ad some serious weight at the keel, to make her steady, and will "popup" if bring to side eg. I rasie some rigging, not to much for "her" -Just to get her going. Kind of like the Vikings did once And leave for open sea. What will you say will be the problem?
I'm not talking about "the optimum sailing angel, or any resale value and so...
Let me know your "seeing" on this subject.

(I can see why Sven Yrvind and others use there own skills and calculate and save a minor fortune)
"And when thinking about it: "the sunset is the same in a rowingboat for 10 USD as in a 45 foot Hallberg Rassy for 150.000 USD"

<mod note Threads Merged because I don't understand the difference between your questions "Easy Way Out" and "Have to Know". Despite the preface, it appeared really the same conversation taking place in two different threads, now merged>​

 

Hunter 25. And WHY??? specify please.
No I don't have any yacht design skills! That why I'm asking. but you sure do so let me in on it then...

And as I sead: "have nothing to do with my on going boat, coz' I'm consulting an expert on this"! (once more!)

 

hi there
I come from a similar background. (no formal training in yacht design, only practical knowledge of boats)
my advice, for what its worth, is that there is allot to be learned from books and asking the right questions, start off small, and don't rush things. with this in mind anything is possible.
good luck!!!

 

The vikings developed boats through centuries of experience. They didn't just built something and went pillaging in it. Beind scandinavian I can't give you the advice that the pointy end goes in the front. It is harder for you guys.

 

You said you are building a boat. Do you mean you are building in the future or I misunderstood that it is being built?

 

Gonzo my friend... kee...??? I am building a boat right now Yes! But I am NOT Without experience ok? Just buildingplans/ drawings...
You sead: (to make thing clear)"You are building a boat without experience" so the answer to this is NO!
