The question is : Are old (1970-1980) I.O.R.-cruisers good for happy cruising on a budget?

For about 10-15000 euros, do you feel that it's a valid option a 27' racer-cruiser (more cruiser than racer) developed from an ¼ ton I.O.R. successful racer, like the danish Granada 27 or the french Jouet 26, for summer cruising in Mediterranean (light winds)?
Granada 27 Danish (500 units manufactured! plus about one hundred in Spain under license as "Noray 27": http://granada27.dk/Top/Granada27/Fotogalleri.htm , http://www.boatshop24.com/web/en/werften/s/g/granada/index.htm .

Jouet 26: http://remi.alcina.online.fr/hasard/hasard.htm

I do not like racing but I appreciate a lot the "poetry" of the pure sailing and the voyaging at sea.

I would like an X-Yachts (X-99), J/Boats (J/92S or J/100), Suspense (Archambault), or similar, all these at around 30k€, but for my tiny budget (10k€) but for my tiny budget these Granada 27 /Jouet 26 seems to suits me quite well.
My program is 3 summer cruising months, my wife and our two kids.

Are these IOR-cruisers really amusing to sail?
It appears that they have an exquisite tiller feel, as french and danish magazines says (see the pdf extracts at http://granada27.dk/English/Granada27/Facts.htm (danish) and at http://remi.alcina.online.fr/hasard/essai-voilesetvoiliers.htm (french).

It appears also that they are very tender till they reach about 30 degrees of heel, very bad in directional stability (deformed hulls!), difficult under spi in the breeze, rolling as dancers downwind and at mooring ...... but all that I can accept it if the feelings are worth, true exciting, safe and live sailing experience, which I hold to communicate to my young family.

Can anyone give ratios for this boats?

Thank you for your opinions!
(Ok also in Italian, Portuguese, Spanish, English).
If possible please send copy well to me to macintoshzoom at lavabit.com

Why not? There are many around there already. Just look for a sound, well built and maintained one.

Here some estimated numbers for the Grenada 27, as per data in the pages you posted:

INPUT (For the heavier version):
Loa = 8,28 m
Lh = 7,80 m
Lwl = 6,40 m
Bmax = 2,78 m
Bwl = 2,50 m
Draught T = 1,75 m
Body draught Tc = 0,31 m
Disp = 2720 kg
Ballast = 1200 kg
Sail area = 32 m2
Mast height = 10,84 m
Heeling Arm = 5,04 m
Power = 9 KW


OUTPUT
Length/Beam Ratio (2Lwl + Lh)/3B = 2,47
Lwl/Bwl Ratio Lwl/Bwl = 2,56
Ballast/Disp Ratio W/Disp = 0,44
Displacement/Length Ratio D/L = 289,41
Sail Area/Disp. Ratio SA/D = 16,69
Sail Area/Wetted surface SA/WS = 2,22
Hull speed HSPD = 6,14 Kn
Potential Maximum Speed PMS = 6,85 Kn
Velocity Ratio VR = 1,12
Capsize Safety Factor CSF = 2,01
Motion Comfort Ratio MCR = 21,65
Roll Period T = 2,44 Sec
Roll Acceleration Acc = 0,11 G's
Stability Index SI = 0,88
Angle of Vanishing Stability AVS = 120 º
Dellenbaugh Angle DA = 19,86 º



Cheers.

Thank you Guillermo.
Do you have at hand (or links to forum posts) ratios about some of these from the European market?
e.g.:
Jouet 26
Etap 26
First 25
First 26
First 27
Dufour 1800
Puma 26
Trident 80
Conati 26
Jouet 760
Kelt 8
Noray 27
ECUME DE MER
SANGRIA
POKER
TONIC 23
FANTASIA 27

And how they compares with their low draught/lift keel sisterships:
ETAP 26 QR
KELT 7.60 DL
FIRST 25 QR
FIRST 27 DL
JOUET 760 DL
GIB SEA 76 DL
KELT 8 DL

And ratios about the X-99 (X-Yachts), J/100, j/92, j/105, J/109, Suspens, ideal holiday boats to me for around 30K€.

Just give me any data that you really have at hand!
Thank you!

I'm sorry but nope, I have none of those.
But you can search in: http://www.image-ination.com/sailcalc.html
or calculate there the parameters for the boats of interest to you.

Cheers.

For day sailing with a crew IOR is fine,

If you are into cruising with the family , or a small crew , or using a self steering an old CCA boat will be far more comfortable , and safer.

Since its older , CCA boats are even less costly.
