Yes I disagree with that. Trimarans don't have water ballast and as I have showed you don't have necessarily to have less buoyancy. The Neo 400, the performance cruiser that I had posted above does not have water ballast and you are going to see on the next years most performance cruisers adopting the inverted bow simply because it works better performance wise.

An inverted bow is not necessarily wave piercing, in the sense it works on the that fast motor boat. There is many ways to design an inverted bow and the objective on a sailboat is to diminish wave drag with a better dissipation of the wave energy and with less spray not to pierce waves passing through them.

Fareast 31R

And people with such skills ought be compensated properly, in my opinion (with all due respect to skilled boat builders in China and Taiwan).
That has already being happening and the last boat is beautiful. I saw it on Dusseldorf and life is even more impressive. I mean this one:





A Simonis Voogd design made for Fareast, a Chinese company. This one is not a boat made by an American or European company in China but a true Chinese boat. They are all very young and very enthusiastic and I believe they will go far.

This boat the 31r has a base price of USD 140 000 euros and that is pretty incredible since it is a carbon boat including carbon rig. It comes without sails and white. The red one costs more USD 3750.

The dimensions point to a true rocket:

Displacement - 1800kg and from those 1200Kg are ballast

Draft 2.10m Lenght 9.80m, Beam 2.95m, Sail area upwind 65.0m2, downwind 161.0m2.



They have a boat that may interest you, the Fareast 26. I have already posted about it.

Paulo

Yes of course but that is not what I am saying. If you look at the two drawings and what I said:



"If a more traditional bow was used the bow buoyancy would be smaller for the same LOA":

[/quote]

You will see that we are not talking about the same thing. I am talking about the same LOA and LOD and you are talking about hull length.

In fact I think that your boat with the conventional interior even with the same hull length has in fact a superior interior volume (we can see that on the plan, on the forward part), in one word is bigger and I have said that previously:

"For a given purpose you will not be designing a smaller boat on the deck and interior space when using an inverted bow instead of a vertical or slightly inclined one, so in fact you will get more buoyancy using an inverted one.

This was what I meant to say. Of course if you maintain hull length you will have not only less buoyancy on the bow but also a smaller boat not only on LOD but also in interior volume and space and what makes sense when talking about a similar sized boat is interior space not LOA."


Maybe after all we are not disagreeing

One of the biggest advantages that I saw in an inverted bow is the possibility of keeping on the waterline a more rounded profile (like they are doing now on the Open boats) but having a shape on the superior sections that will offer less drag to waves, dissipating better the energy. Of course it will be complex because it is also needed to provide a shape (on the top) that will took away the spray from the deck. The more rounded shape at waterline will increase in much the buoyancy and volume (a bit like on the bath tube bow) but an inverted shape can provide a better wave penetration than on the bathtube bow. Interesting stuff in my opinion. I believe we are going to see on the next years some funny looking bows on race boats and performance cruisers

Paulo

Re: Interesting Sailboats

Paulo:
We built 120 of these Flying Tiger 10 meters in China. We also build a 7.5 m model.
We did this project over 5 years ago.

Flying Tiger

Nice boats:

Flying Tiger Boats

The difference is that while this is an American Company making boats in China, Fareast is a Chinese company making high quality boats, the first one.

By the way, have a look here:

Langfahrt: Einblicke in eine Blauwasseryacht - Panorama*|*YACHT.DE

Lots of pictures with nice comments.

The Aluminium boat you designed and was made in Holland is today a famous boat in Germany due to the new owners that are very popular cruisers.

Re: Interesting Sailboats

Thanks a lot Paulo!
I don't speak German so I have no idea what the article says. My son speaks German and I'll see him on Sunday. I'll see if he can translate. That's a great photo. I truly appreciate you calling this to my attention. I have communicated with the owners but I know nothing about them. Maybe one day I'll be known in Germany. I really am a huge Wagner fan.

I'd love to know the thinking about starting the chine so far forward. I have my own ideas but I don't trust them. Yet.

Re: Interesting Sailboats

HMMMMMMMMMM
get my copy of "sailing" today, and mr bp and paulo are arguing over one of the reviewed boats.....well, maybe not arguing, but ea saying something different, using the same words...........

Nice review of the fareast and sf3600 in the recent issue Bob! now if I could afford the 3600, or the 349........Id be a happy camper. THen again, I brought home a "Showboat" rag from work......spouse says something to effect these boats are in a different league.......a mere 14-15Mil US$ for one of the sailboats listed.....mid 100' arena......hmmmmmmm

Marty

She drives me boat,
I drives me dinghy!
