Butterfly got weighed

scarab · 26-09-2008, 12:56

Today Butterfly ( a Fastcat 455 ) got weighed.
With empty water and dieseltanks and without the extra
sails ( only main and jib on board ) the final figure is 8600 kg.( 18959 lbs )
So with a complet set of cruising gear and full tanks one can state that
a Fastcat 455 weighs about 10 tonnes ( 22046 lbs )

Who is the winner?

I don't know what it is supposed to weigh, but that seems pretty heavy for a boat that is supposed to be very light. Just my thoughts...

malovich · 26-09-2008, 13:38

what hull # is yours? I thought the fastcat designer on this forum stated that the 455 models will be getting lighter as they improve their production methods.

hmmmm, I didnt get involved in the previous thread, although read with interest, what I though was robust, but reasonable debate. I was off the forum due to travel for a while and was rather surprised at the recent out comes. Like all of us I am interested in the modern lightweight contruction methods. I built the first Airex foam sandwhich Roberts 36 in Australia in the late 70's, and vacume bagged a paper tiger as well so have some appreciation of these methods. I have recently read an article from the guy who runs MTG custom boats in Aus. and he was saying resin infusion can lead to a heavier boat due to resin actually being left in all the holes and capillaries required to get the resin to the fibres. Seems plausible I guess, but then they use vacume bagging......so it I guess with most things it really is buyer beware......Maybe we need to get Jamie & Adam involved from the Mythbusters ! Any chance the load cells were out of calibration......

So I would have lost £1k if I hadn't got some wiggle room on the weight.

BTW 8600 kilos seems a very round figure - is that posted on the buyers blog or something? (edit - yes it is!).

Wait for comments from Nordic Cat and Fast Cat435... I don´t remember.

Nordic cat · 26-09-2008, 17:03

I placed a bet on the boat being heavier than the weight stated by the builder on 2 or 3 different occasions, somewhere in the region of "6400 kgs including all options". I am actually suprised that it was so heavy without fuel and water!

I wonder how far from the mark the weight claims for the earlier builds were, as this is more than even the claimed weight of the prototype boat.

So I think Gideon owes me 100$ that we can use to buy a few bottles of wine and share with any forum members who pitch up.

I also asked that if he was wrong, he should stop posting "deflated" weight figures and making exaggerated claims, as not all of us here know enough to be able to filter out the right amount of "mis"information.

The sad part of this, is that there probably are people out there who have been reading all the claims on weight saving here on CF, and maybe gone ahead and ordered a Fastcat, thinking that they will get a boat at the cutting edge of weight saving technology, and the benefits and speeds this implies.

I have spoken to a number of builders, and a guy with 13 years experience working for a big Swedish foam manufacturer, who also builds cats.

Based especially on his reccomendation, but collaborated by a few other builders, I decided NOT to infuse the complete hulls in one shot, but rather do the outer skin, bond the core and vacuum bag, followed by the infusion of the inner skin.

This makes for a safer build, with lower weight they say. We will see if the weight predictions hold true in about 6 months when the shell of my boat is ready.

Here's to sharing a glass or some glasses of wine with some of you.

Gideon you choose the place, and we will agree on a date.

Regards

Alan

David,

In hindsight I should have taken you on

1000£ can buy a really big headache if we converted that to the type of wine I normally drink

Put it into the kitty for something extravagant for the boat before it gets used for more mundane stuff..

Gee, and here I am building a backyard boat from plain old glass and balsa, 44 feet long and 5.2 tonnes.

scarab · 27-09-2008, 02:36

I got the info from the owners blog: of Butterfly and Barnacle
I've been following the building of the Fastcat #3 ( African Seawing / Nieuwe pagina 1 ) and that's how I learned about the Butterfly.
