Re: CATAMARAN DESIGN and BRIDEDECK CLEARANCE

giving someone $50 for the same 2 cents you can find elsewhere on the internet seems a tad unrealistic to me, but I wish you good luck none the less!

I wanted to expose people and Brokers like this to the budding Cat sailor who has a lot to learn about Cats and end up buying things that float, thats why it is called a boat, but it does not sail well because the production Cats do not have any of the 6 requirements I talk of.

.

All I want to do is give potential Cat buyers somewhere they can go to ask questions about potential Cat purchases they might make, before they make a mistake, like so many Cat owners who are disappointed with what they bought, for one reason or another.



Give me 2 weeks and I should be Online with my Website but, there is a small fee, but you said you did not thinks so, [ No that was me] I take it you don't thing buyers will pay $50 to find out what I know, we will see.

I am looking forward to helping cat buyers choose the correct boat before they buy.

Best regards

Hi,

I said I don't think so. The reason being as a non professional I assume you are going to have a on line pay by credit card details.

Will this site be secure and what are the chances it will be hacked un be known to you for a third party to have access to all your credit card details should anyone give their details.

2nd warning bells: You have not stated whether you have at least 4 endorsements from Multihull designers and have been reviewed by them, your formular to give credence to your claims.

3rd Warning Bells: How are you going to assure people and guarantee that you will not sell all the submitters credit card details to a third party, particularly on the internet with all the scams that are going on.

If you are in fact genuine and I appreciate what you are trying to do and whish you all the success possible to wish.

Have a suggestion for you which I think will help overcome the above reservations.

(1) approach some non profit organisations to see if they would agree to be in partnership. Hence you would give the submitters say four choices with hyperlinked loggos to donate to and they would receive a code to enter your web site once they had donated. The Charities would have have a separate space next to theirs in a high profile area. You would negotiate with them a % of the donation to be forwarded to you say every three months. The % would be in the vincinity of 20%. You don,t mention any amount on your web site. You may find if you can pull it off, [need to be a good salesman and professioal ] people will donate $1000, $1500, $2000, $4000 and a occassional $10,000 donation providing they where worthy causes.

Here are some hyperlinks to worthy causes,


The RSPB: Save the albatross: New Zealand

WWF New Zealand - Hector's and Maui's campaign

Little Spotted Kiwi - BNZ Save the Kiwi Trust

Re: CATAMARAN DESIGN and BRIDEDECK CLEARANCE

Hi again petercheck,

CREDIBILITY was my first requirement 5 years ago when this all got going.

I extracted the design mathematics for my 'Power to Weight Ratio' spreadsheet (Bruce number) from the design pages of a top quality Catamaran designer in Australia, there on the web for all to see.

I built my Spreadsheet using this information that they use when designing Cats/Multihulls to establish what works and what does not. I am not preaching MY thoughts and feelings, I am preaching THEIR design knowledge, not mine.

I am not presumptuous enough to think anybody is interested in my views, that is just like another Blogger saying what he thinks, and whats the value in that, it's not credible.

Your right, nobody knows who I am, I could be any old Blogger voicing his opinion, it will take time for my reputation to filter through but, I can tell you it stops the Brokers dead in their tracks, when you ask the questions I ask and request the data I require for my 'Bruce number' calculation.

The method of payment I will use is via PayPal which I am told is secure, I don't see the Credit Card details, only the payment. Then I send my report to the potential Catamaran/Multihull buyer, telling them what NOT TO BUY if there is something that shows up in my calculations, and you can't get that for 2 cents on the Web anywhere.

I have met hundreds of new Cat owners who are disappointed with their purchase. They think all Cats are fast, it's a misconception that many fall into, blinded by Broker and Press garbage they talk and publish.

Try me out for FREE, send me some details of a Catamaran you would like to buy, send it to my bazcatana@yahoo.co.uk Email and I will send you a Form to fill in. Return that to me and I will tell you what I think.

Don't play around, try and be serious, I am trying to HELP buyers choose a Cat that they will be happy with, I'm not selling anything, just helping buyers find the ideal Multihull.

Regards

Barry Parkinson

Have you had a chance to rate this particular design. If so could you please advise how it matched.

Multihull Dynamics, Inc. - Home

And it's worked up by naval architects, not someone looking to be funded for his search.

Lessons learned are opportunities earned.

The accomodations are more like a smaller loa monohull, and way less comfortable than a cat, but that is the kind of compromise I am willing to make personally.

If you want that standing headroom bridgedeck, the compromise is high windage and poor bridgedeck clearance, at least until you get to a really big cat IMHO.

I agree. If you want to have performance and seaworthiness on a cat you would have to look over 40ft, more likely 45ft.

You can have that on a 35ft trimaran and even on a 32ft one. But the prices will remain very high and a 35ft trimaran has the interior space of a 32ft monohull.

Regarding price a very good 32ft cruising trimaran, like the Dragonfly (with a very good cruising interior, even if small) it will cost as much as a 41ft performance cruiser like the Salona 41 and almost as much as a 45ft main market mass production sailboat.

The seaworthiness of the 32ft trimaran will permit it to be sailed offshore and even cruise Oceans but has nothing to do with the seaworthiness of some monohulls with the same price.

So, if you have the money it is your pick. I confess that it should be very funny to oversail with a 32ft trimaran a top performance 50ft cruiser

For Richard Woods thoughts as well as Terho Halme's catamaran design formulas look here,

Catamaran design

I have to make a comment here. At 20 years old I loved the feel of a tiller in my hand of a boat designed to point as high as possible.

In my 30s I noticed my wife wasn't as appreciative as I was of this point of sail..

In my 40's, I couldn't get a lady on the boat to save my life.

In my 50's I bought a catamaran. The Lady loves it and at 40 lbs heavier than I was in my youth, I am no longer appreciative of beating my brains (and my butt) going to weather either.

So, It depends where you are in life and your point of view (Pun intended)
