Hopefully he sails, and wants to know more about your boat instead. I think you need some sleep... or coffee...sleep is better for you...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

It doesn't really make sense to compare speed or much else. It depends on the conditions and measuring method for one thing. You could exceed theoretical hull speed downwind in 20 knots as you were likely surfing. The performance rankings phrf differ from place to place but can easily be googled.
If you want to know how fast you really are comparing like with like go racing. Then you will see boat speed is only part of it.

Well yes, Dog, I guess I was right. And I'd like to think that it happened in under 11,000 posts is some type of record as well. Keep trying, I'm not counting. (g)

My Pearson P30 has an LWL of 25'. Theoretical hull speed is 6.7 kts. On the way up to her new home, I saw her hit 7.something kts on a close reach. One of her old racing crew said she regularly hit 8 kts or better. PO says she once did 10 kts flying a kite. (I don't recall what tack she was on.)

I don't know my hull speed, (theoretically very slow), but the best I've done was 6.8, in 2 foot seas, with 25knot winds, close reach, (well not that close, but trying very hard). I used to have a Santana 22, fixed keel, and I had her up to 7.5 on a broad reach. That was a fast boat....My father has a Newport 30 MKII and we've had it up 8.5 knots with a spinnaker, but it usually maxes out around 6.5.

Shiva has a 29' LWL and I've seen 8+ through the water, but this is rare. She'll do a steady 7.6 on a reach with clean bottom and 15-18 knots of breeze.

We got 8 kts once, surfing downwind. The boat does well on all points of sail, for a cruising boat.

I remember this thread: We Hit a Tree....

I've seen 5.8 in the little boat and expect much better, wilder white knuckle stuff when I rig the chute. She should plane in 18+ downwind. Good thing I have that deep, aftermarket rudder.

The square formula for the hull is only at 5.2 knots but I regulary sail over that, is that normal with other boats? I'm curious to hear what others say. I would also like to know the PHRF ratings of other sailboats as well.
You should be able to hit 7.0 knots in less wind then that in my opinion. How much were you healing?? In that kind of wind I would expect over 6 knots with the main reefed and the jib partially furled, but I don't know if I would go much faster than 7.2 no matter what I did. I don't think I would use full sails in 25K winds, and if I did I'm not sure that it would make me go faster. My knot meter has gone as high as 7.8 (it was less than 25K winds)but only for a brief period. We seem to hit 7.0 on a fairly regular basis and is sustainable when the wind is right, we consider that good sailing. There is no way your boat will only go 5.2 knots, we motor faster than that.
