F33 has been launched

Beautiful boat!

I liked especially the tilt back daggerboard style rudder - this could become a future standard for multis (and high speed monos), if light enough.

The design is conservative, keeping most of the old (tried and proved) features of the F-boats. This is a comercially adequate choice, given the market segment they are aimed for - cruising.

I also noticed the following technical improvements:

- Float's center of flotation moved forward
- Float's deck flush with the hull and more rounded
- No recess for the beams
- Only professional building allowed
- Less exposed upper struts

The 5 new features are shared with the Catris and some of them also with other modern tris, so I assume the F-Boats are being designed with a more modern view.

The changes are atributable to the natural evolution of the concept - but very probably to the competition too. It is clear that the f-boat design is improving in the right direction.

This is all good news: competition benefits the consumers - us!

Cheers,

the f-33 looks like a great boat (i saw it yesterday for the firs time i realy like those beams) light and power full, but there was not much difference in speed/performace wen i was along side it with my f-28R the winds were about 15-20knotes some gusts too 25 i got up 18knots on the screacher run
i would love too see the boat with spinaker going
i think it could all so do with a bigger mast
but i still looks like a great exiting boat

The 33 is obviously intended to be a fast cruiser, so it is not necessarily expected to outperform your F28R. If you are looking for performance, the Catri (my boat) should interest you.

Do you think the taller 'R' mast would improve things (assuming the first boat doesn't have it)?

im shure that it would ,and i think the st(supa tri) vesion
wich has a taller rig and is much lighter would make it alot faster

That's what I figured. Well regardless it looks great and it's a shame that our kiwi 'pesos' will mean the boat isn't likely to be a goer for import nor the demand here to justify a local build - I'm hanging out for the unpainted maximum-DIY hulls-and-beams pricing!

cheers

Luiz,

Those foils at the end of your Catri's amas, do they perform well even when kelp is around?

Sigi,

This was the first question the oldest and most experienced multihull sailor in Brazil asked when I first showed him my dream boat. All fins are potential kelp-catchers and more fins = more kelp to get read of...

To date, none of the Catri owners I am in touch with complained about kelp or debris catched by the ama's foils. I guess the problem is minimized because the foils are swept-back and/or because the ama's foils are designed to go in and out of the water in higher speeds.

Anyway, I think the cross of the rudder blade with its foils is a stronger candidate to catch kelp - but the rudder is also easier to clean.

There is another risk as well - solid debris in high speed. I was informed that the guys in San Francisco exceeded 30 knots, so I started worrying and asked the builder in Brazil his opinion.

He told me not to worry at all and that a worker once fell very heavily over one ama transom, the foil geting all the load. The worker broke his leg, but both the foil and the foil/ama seam remained unscratched.

Cheers,
Luiz
