The second LR2 hits the water this weekend. Two boat tuning begins. A third boat is in the works and possibly a fourth by the worlds. Anyone interested should contact Ian Lindahl at Ian Lindahl @ [email]ian_lindahl@yahoo.com.[/email] The LR2 is currently configured to best handle as sailor in the 75kg weight range. They are currently looking at a larger volume LR2 for sailors in the 90kg-120kg weight range. It is on the designers board right now. I will post something more as the information comes forward. It also seems that the platform can be designed for a choice of rigs and beams.

Tom, did you manage to get any pic's?

I did get some pictures and will go through them tommorow and post them here. There is a link earlier in this thread to boatdesign.net with some of the current pictures with Ian on the boat.

I wonder what the point of leaving the beams proud of the hulls is? It seems that they would add drag when a wave hit them.

Im no designer but after looking at the blog pictures and the narrowness at the top of the hull, I think common sense would dictate that you extended it a piece so the beam had something to sit on. Its also probably shorter than other hull beams as well and therefore lighter. The fairing looks like it will shed a good bit of the wave as well.

This is the most recent posting on the boatdesign.net thread about the LR2 and I think that it will tell you more about the hull shape then I could.

Some shoreside pix of Ian Lindahl and the new creature at Silver Lake Invitational- Michigan.

did you mean to attach some pics with this post ?

Windswept, thought you were going to post some pics of Ben's boat?

My camrera crashed, will probably get some new ones on Tuesday.

Hmm- Trying to post the pix again.

Try another

My new 6.1m by the same designers, same bow, and hopefully a lot faster, see more pictures on the formula 20 forum

To the people recently mocking me for suggesting to go to an even more dolphin like shape.........your crow is ready.

Lets not loose sight of the fact that at this time this design is only a bunch of pixels on a computer screen. It hasn't proven itself in anyway.

From the mistakes and lessons-learned in the F16 class I predict this design will be a right dog to sail in any conditions beyond light winds and flat water.

Be careful that the crow won't find its way onto your plate.

Pictures look good. Has the the A cat been tried against any other boats to see performance against them?

Not new. See the pictures of a 12 year old trimaran.



Each float has a volume equivalent to 110% of total weight, so it really pierces waves at low speed. At high speed the bow is lifted by the foils.

I am happy with the situation as it stands Wouter. Remember, I was only saying it was a good thing to try in the persuit of performance. Not that is would be a sure fire winner........just that nature has things to teach us. If there is something I see as a stand out DF I do not like it is how very low the rear beam is in relation to sea surface.
I include a photo of a German design looking remarkably like a tern.
What is it said about contempt before investigation??

Hey, I'm as interested to see the results of this experiment like anyone else. If somebody is prepared to spend money on this design to have it build and tested then the more respect to them. But this stance still doesn't mean that I expect it too succeed. Compare it to a night at the Casino. All very interesting and enjoyable but I'm not desillusioned enough to expect to break the house even when there is a very small chance that that may happen.

If nature teaches us some things then it is that sailing on the water surface is NOT efficient. Afterall how many animals do this ? Even animals that reside on the watersurface alot. Like ducks, swans or pinguins take to the air or dive under water when fleeing or looking to get somewhere fast.

Luiz,

For example is not really well developped. Afterall the centrehull is still very much a conventional shape. If that had been of the same shape as the floats then you example would have been a proper one in relation to this new cat design.
