Hi Dick,
actually my intent is to use my RG65 as the basis for the new rig experimentation and not for competition, unless I will discover that they are highly competitives because of the rig performances.
Cheers
Claudio
Hi Paulin,
Hi note the good progress of your construction , your adventure could better profit of a dedicated tread !
This may be of some help :

hi Claudio,
Thanks a lot for the links, very helpfull.
Concerning a dedicated thread about open60 : I should, but you are the only one on this forum to show interest in something else than IOM or RG’s… so i send my pictures directly in your threads.
I will stop !
Ciao,
Paulin
Hi Paulin
I was suggesting to open a new tread in your interest , because a tread title as “Open 60” or “VOR” would attract more persons interested in this classes
If you wish to continue on this RG65 tread, please help yourself.
Cheers
Claudio
Hey Paulin,
Although I am currently building RG65s and and IOM, I am always interested in all build columns. This includes your project as well as the IACC120. Please keep post messages and loading photos!
Cheers,
Eric
Paulin,
I too agree with Eric. I look at all building post from other classes. I get lots of ideas that are helpful no matter what class boat I am making. Thanks to all the builders that post on this site I have gained much knowledge on model building.
Grazie,
Michael
Coming back to the tread subject, here some more pictures of the Fuxia65 construction !
Pics F27 & F28 shows the laminated cover for the deck
F30 is just the hooking set for the jib boom
F31 shows the mast steps composed by the carbone tubes positioning and bonding - include verification of verticality and alignment. The Fin leading edge being the reference line.
F32 shows the assembly of all internal supports, here some effort will be made in the future in order to reduce the overall weight.
F33 shows the deck laminate with reinforced access openings - the weight remains 30g - next effort will be to get a gain of 10g.
F34 shows the lateral view of the Fuxia where can be observed the flat bottom and the deck slope. In particular the deck slope respond to two choosen criterias : gain weight and styling .
Work still to be done :
- Deck bonding
- Sheeting assembly
Cheers
Claudio
Fuxia 65 - typical operation for deck bonding !
Note : for better bonding I used normal 24h epoxy loaded resin with silicium powder
Claudio
Hi everyone,
Thanks to Eric, Michael and Claudio for your encouragement !
I’m convinced : I will start a new thread showing my open 60 and IACC 120 building.
Nevertheless, there will be many differences with Claudio’s threads, but two major : I can’t work as fast as he does, so there won’t be 12 pictures published per day… and i will have more questions than answers…
Well, we’ll see.
regards,
Paulin
Fine Paulin,
I will follow your development.
Some times I use some small cups as weights, indeed they contains birdshot. Their weight are around 1kg and I found them very usefull also when I want to exercise some pressure as deck bonding !
Some persons intending to use the birdshot as ballast or even making bulbs, ask me what is the specific weight of these small birdshot.
Because of the ecologic Rules these small birdshots are actually composed of lead, tungsten , bismuth, antimony, etc and the specific weigh is rather low and is variable from one make to another. I just tesd the ones I have and is not very encouraging to make a bulb.
The pictures below show how much the weight drops. Obviously the spherical form includes air that participate to the reduction of the weight.
First I check the volume of the cup by filling up with water and found 139cm3, then I replace the water by the birdshots and found 974g.
The actual specific weight is therefore : 974 / 139 = 7.00 g/cm3 or 7kg/dm3 - almost 60% lower then lead !
The lead specific weight is : 11.34 kg/dm3
That’s is , I’m going to finish up the deckt
Cheers
Claudio
Almost ready !
Time to start the Fuxia-65 Classic Rig.
Cheers
Claudio
I drew a couples of gooseneck plans and finally I made a mix off, using bit & pieces available at home !
Probably the solution “A” is lighter.
The actual mast + gooeseneck, without spreaders and cables/turnbucles weight 51g
Cheers
Claudio
Sails are ready !
The batteries are charged !
Ready for testing in the water, wind permitting since a week above 15 kn and more !
Cheers
Claudio
Congratulations Claudio! They look good.
Now you have one boat for each hand!
Hi Niel,
thanks, not really, my “fleet” is composed of 3 RG’s
For the time being this conclude the Fuxia “story”
When available some video will be presented, the one I miss one month ago…
Cheers to everybody
Claudio

I noticed that you glassed the plug then added tape. and then made your hull with second layer of glass.
Did you add the first layer of glass for durability of the mold?or was it needed to get the tape to stick to the foam blocks?
Did you need to apply any kind of release wax to the tape or did the complete hull “pop right out”
I was thinking about getting some of the heat activated shrink wrap, the kind they use to cover boats in the winter not sure if it would act the same way as the tape does
did you do anything special to outside of the final hull to get a smooth surface, like vac bag or the latex or stretch film
Hi Marc
1 - Yes correct
2 - the 1st layer was to protect the foam and eventually use it for filler application not supported directly by the foam.
3 - No wax needed since the packing tape do not adhere to the glass/epoxy.
4 - Hot air may melt the foam !
5 - No , some precoat paint only before wet sanding.
Cheers
ClaudioD
- so I would not need to do the double glass application unless I was looking at multiple uses of the hull…
- though about that but I think those heat activated shrink wraps use a hair drier…or some do at least…
- In theory…could I use shrink wrap or a vac bag to get a smoother outer hull Ie less filling and sanding…
another question…
the foam hull you made is it the shape of the hull including the deck. IE did you use the hull mold to make your deck as well?
Also, take a look at my newest pics on the build log I started. what are your thoughts on the strakes I added and the center “keel” will that give me some headaches in removing the glass from the mold…
Hi,
6. No, separate lamination used and made on a windows glass, see message 102
New pics ?
Cheers
ClaudioD
here are some new pics…I fixed the funky bow issue…
