Hylas 46 polars

[molly1]

Is anyone able to help me find the polars? I have searched and searched no no avail.
About to put a deposit on one for sale in Brisbane Australia but concerned about it's performance.

Contact German Frers.

This is from the H46 brochure:

Thank you very much.

I don't think you have to worry about performance. I you really are, consider a TP52.
I don't have a Hylas, but noticed on predict-wind some polars, Hylas 44 and 54. Here is a copy of the 44.
But still wondering how accurate these polars are anyway. I guess the polars supplied by the manufacturer, show results with perfect fair bottom with new antifoul, new expensive sails and a very experienced skipper.
I would say Hylas is in the top 10% for its size, without going to racing yachts.

^^^^^
I believe that many such polars are generated from theory, not actual performance measurements. They should be taken with a whole truckful of salt!

I have done some deliveries on a Hylas 54, and for that boat (with new sails) the numbers from Hylas I found very optimistic. That's not to say the boat is a dog, it's not, but the manufacturer's numbers are not for this planet.

Information here: https://sailboatdata.com/sailboat/hylas-47/
suggests that the Hylas 47 was designed by Sparkman & Stephens.
German Frers designed the 54.

Wrong boat; go up one:
Hylas 46

reality is every cruising cat can do 3 kn VMG against wind in 10 kn true and at around 17+ kn true 5 kn VMG. Of course in flat water. Reaching is different story. It all depends on your setup.

So, how does this relate to the OP's query (if even true!)?

after 10 years of sailing and ~ 30k nm noticed all cruising cats do rougly the same. Hylas 46 should be no different. 40 ft cat, if you want to go 15 kn, you have to be ready to push the boat thru wave barier from 8.4kn to 11 kn or so. For 46 ft cat, it is 9.2 kn to 12 kn. If you stay below that limit 46 ft boat has some advantage in 8.4kn - 9 kn range but the rest is the same. People expect cats to have wildly differing performance which is false.

The best way to compare a boats real performance is to race it against other boats. For monos that real performance is evaluated by a committee of experts and results in a Performance Handicap Rating (PHRF) number. It is not perfect, but it cuts down the bar talk. There are other handicapped systems, but they are expensive and not as widespread.

In my area of the world Catamarans rarely race against each other, and I
am not familiar with a similar system for cats. There might be one, and I would be interested in hearing more about it, and where I could get the rating numbers for various designs.

Cats and almost never race against mono's. When they do, they are scored as a separate class. Any comparisons between cats and mono's are just bar talk.

Lee pointed out my error referring to the Hylas 47 instead of the 46. The link to Sailboatdata that he gave answers the OP's question quite emphatically. . J/boats are generally considered to be performance-oriented. The SA/disp ratio for the J/44 is 21.28. The SA/disp ratio for the J/46 is 19.71. The SA/disp ratio for the J/42 is 17.40. The SA/disp ratio for the Hylas 46 is 20.46. It will not be a slouch. It has the sail area it needs to perform well.

Donna's suggestion to look at PHRF ratings (above) is also a good way to compare the performance of different boats.

I'm still confused here! The Hylas 46 is a cruising oriented monohull. I don't see what your thoughts about catamaran performance have to do with the OP.
