Hunter 27 with twinkeel

[Jan van der Klooster]

Hello,
Is there somebody who is owner of a Hunter 27 with a twinkeel (also called bilgekeel in UK) with draught 1.05 m who can tell me what is the performance : as fast as a Hunter 27 with a wingkeel 1.05 m or a bit slower? And what is the difference in sailing windward: as close to the wind as the wingkeeler 1.05 m ?

I want to buy a Hunter 27 (Legend 27) with a twinkeel but we don't know them in the Netherlands where I live. If positive I will go to the UK to test it and maybe buy it.

Thank so much!

Jan

PS: I already got some answers but that was not quite clear to me. Maybe because of the language !

I can see where language might be a problem, especially with Glenn's very technical answer. He is saying that since the hull is his design and there are two keels that it theoretically should be slower than a fin keel. That is because there is more wetted surface or "drag". But he goes on to say that he has heard owners tell him that they feel it is faster in a "breeze". But he does not define breeze. I would guess something over 10 knots.

My engineering sense tells me it could be faster with a nice breeze. My logic is that the heeling angle would be less due to the weight of the windward keel. The leeward keel would be providing more lift. The boat is faster when it is flatter. Off the wind you would expect it to be slower. Again because of the increased "drag".

But the idea of finding a PHRF chart that has both boats is the key. Just Google with "hunter 27 phrf" and you will see several charts. I looked at a couple but found nothing for a twin keel.

P.S. Just found this which contradicts what I thought:
