Solo16 Sport Trimaran

I have just published a new article on my site for a trimaran I have been developing for a gentleman and his disabled daughter.

http://www.lunadadesign.com/solo16-sport-trimaran.html#more-155

The Solo16 Sport is a progression in size from the nicely received Solo12 and 14 models that preceeded the 16. All three of these boats are sit-in style craft with either hand, or foot, controls for the rudder. The 16 Sport also offers the potential for sitting out on the tramp with a tiller extension. With its enhanced payload for two daysailing adults, a solo sailor could enjoy this boat as a compact coastal camp cruiser with a very nice turn of speed.

The boat is designed to be built in the stitch and glue method from marine plywood laminated with glass/epoxy.

Please have a look and let me know of your comments, or criticisms.

Just wondering why you keep posting these "look what I have just designed, please give me comments" postings?

 

I believe it is self explanatory, no?

As long as we're on the line here, A-hoc, I'd like to invite you to share some of your work.

 

Yeah, when are we going to see :"Look what I've built"? I've heard a lot about your designs not being delivered-is that right?
How do you plan to keep the man's disabled daughter safe in the event of a capsize or pitchpole? Why would this design be better than some of the Access designs? Does the narrowness of this tri make it more prone to capsize or pitchpole?

You've already seen postings of boats I have built.

No.

The man has his plan in place.

Not concerned with better. The type was specified by the man.

It's not narrow.

 

=======================
Are you telling me that "the man" has his plan to right your tri and save his daughter before the boat has even been sailed and with no input from you?

I'm not on here to self flagellate about my work, I don't need any pat on the back from users of this forum for my work. I'm only on this forum to offer advice and/or guidance should the recipient wish to take it.

 

For the record: I greatly enjoy seeing this type of thread where a designer shares his work and invites comment. Its enlightening for the non-designers amongst us and the critique usually raises interesting points.

I dont see the point of Ad-hoc and Doug's needless personal attacks.

If you dont want to comment, move on.... but dont spoil a perfectly enjoyable thread.

Thanks.

 

Well, I think I asked very reasonable questions. And I've learned a lot about asking questions from Mr. Ostlinds participation on other threads. You reap what you sow-at least you should. He makes unjustified ,uninformed, serious, REAL personal attacks on a regular basis.
But, again, I don't consider what I've written any kind of personal attack. I've studied and designed multihulls for 50 years and built numerous multihulls from rc models to 22' fullsize experimental trimaran/ foilers. But I do this mostly for myself and to develop new ideas and concepts. I've had over 300 production monohull's and catamaran's built to a couple of my designs.
I think serious questions need to be asked and answered-and I don't think I've sunk to the level Ostlind ROUTINELY does.

where does it say this is a personal attack?

"...If you dont want to comment,..." I did, so did Doug Lord. Your assumption is that a comment must be in line with what you want/expect coupled with a "jolly well done mate" pat on the back....

We made our comments, just as you did. Your comments differ from ours owing to our differening points of view.

If someone doesn't want to hear comments, beit good or bad, then don't make a posting!

I personally don't see the point of "selling" oneself and designs on this forum, to me, this speaks volumes. But everyone has their own point of view.

 

Perhaps you are assuming that the man has no experience in these matters. Perhaps you are assuming that he needs help from me when out in his boat. Perhaps you are assuming that the man did not specify certain aspects of the design in the initial brief that addresses this very issue.

So, let's just say for a moment that the man is an extremely experienced multihull racing sailor who has seen many pitchpoling incidents in his life, as well as effected self rescues on numerous occasions with a wide variety of high performance multihulls. Should I be offering-up sailing lessons to this individual, or should I offer-up that which is asked of me in an effort to fulfill his specific needs? An offering that is, at once, aesthetically pleasing, as well as functionally correct for the brief.

I believe that someone on this list has mentioned the term, uninformed, on any number of occasions. Interesting position, that.

 

I merely asked a question-no assumptions that weren't implicit in your post; I'll rephrase it: what is your design plan to deal with pitchpole and/or capsize? In other words how do you envision a man and his disabled daughter righting your design?

 

Chris

There is a difference between offering what the client wants and offering a design that has a flaw or at least outlined all the risks of such a 'prescriptive' design to mitigate any concerns. At the very least, it should "cover" your professional responsibility.

Or perhaps I am assuming you have outlined all the possible scenarios, where the design as he wants it, could cause an injury or worse a loss of life!

 

It's equally enlightening for the designer when entertaining commentary from such a wide variety of contributors. Sure, it can be a harsh light at times, but I find the process fundamental for a broader understanding.

My uncle was an industrial designer for pretty much all his life. He designed many of the everyday household appliances that were used in the 50's and the 60's. When I first embarked on this journey with boats after a long career as a still photographer and cinema cameraman, he told me...

There will be those who will think you walk among the Gods.

There will be those who think you and your creativity have ruined the entire craft.

Then there will be those who have questions of merit... Points to be absorbed and more fully understood... Suggestions for ways to make your effort better. They'll ask questions you have not considered about issues that you overlooked while consumed with the process.

Ignore the first two and concentrate on those in the last group and respond to every question and suggestion put forth and thank them for their input.

Interesting and very simple how that works.

 

Have you read the posted article at my site? Much of what you seek can be gathered from the material.

Once again, in the phrasing of the question, you are assuming that they need to right the design. There are many multihulls afloat which do not have chance one of being self-righted by the crew, no matter their physical condition. Yet, they are used regularly and freely with wonderful rewards.

Beyond that fact, the man is fully capable of turning this boat over through one of several strategies. There are no tricks here, no excessive use of gadgetry on which one must depend, there are few parts to wear-out and fail when least expected, etc. There are several well accepted methods for righting a small trimaran. They have been around for some time now and are easily accessed by means of a simple search on Google.

His daughter can be kept safe throughout the process by typical and well understood means. Rescue, if necessary, can be effected by means of cell phones, marine band radios, personal locator beacons and even EPIRBS. The waters in which they plan to sail are typically well populated and never a great distance from shore. They plan to carry a serious survival bag with all the needed equipment to stay with the boat warm, hydrated and fed until rescue arrives, should it be necessary.

The design of the boat is targeted, specifically, to put the process in their favor throughout a broad range of conditions and scenarios.

The order of march, once the boat is completed, is to embark on a well rehearsed self rescue training process in a wide latitude of conditions, so that the man can fully uderstand the boat, well before he sails with his daughter.

Lastly, the man, in spite of his own personal history, is extremely cautious when engaging any sporting activity with his daughter and they have engaged, successfully, many other sports beyond sailing.
