information on yacht keels

[Farley]

Does anyone know any companies which give out information about the construction of their yachts? and in particular information about the structure of their keels?


I seem to have found that companies are not very giving with this and would love to be proved wrong

You are double posting.

sorry , you just made me realise that my original post was scrambled and not easily understood

Hmm....generally you need to pay for engineering proprietary knowledge. When you do receive free or reverse engineering advise on layup schedules , keel roots, flange design, bolt patterns..... , how can you be confident that this engineering advice will be applicable to your application ?

For general knowledge their is plenty of public information, both of the net and in books, concerning yacht structural engineering. Many times its best to harvest this public info, understand the technigues, loads or construction details, then ask a structural engineer for concise advice to solve a specifc challenge. Its cheap...many times engineers give common construction details away for peanuts...when you do your homework.

Farley, maybe it would be easier if you just told us what you're trying to do. The engineering portion of this "assembly" can vary wildly in approach and application. Without knowing what you're attempting, it's difficult to offer anything other then vague suggestions and general trends. For example, each building material will require a different engineering solution, yet we don't know what material you're referring to. Let's assume GRP, but what type, single skin, cored, core type, internal or external ballast, etc. Give as a hint . . .

ideally aluminium construction.

Give this a try

Apart from obvious reason to keep hard-earned knowledge in-house, most high-load (keels are one of them) engineering solutions do not translate easily from application to application. So giving details involve a risk that solution will be not adequate to this particular application and designers name will be quoted as source of problems. It is quite unbelievable, what weird sets of requirements, misconceptions, "engineering" criteria are sometimes applied by owners, builders, build managers.... .
