what's your top boatspeed in a J boat?


Recommended Posts

 I have no idea how fast we were going odds are most anybody who’s ever sailed a Bigger J boat has gone faster but

while playing on a J-22 in a north west breeze out in front of Southern Yacht Club we rode planing with the chute up on the face of a huge roller for so long it took two hours to get back to me n front of the club.

we knew we were going too damned far but the ride was just perfect

the next day the wind was gone and it didnt return  until the worlds were over 

maybe it was 1990? I really don’t know for certain but it was between 1988 and 1994

Did 13.75 on the J35. Flat water, 1-1/2 oz chute, 27 knots of wind. We were very stable and never wiped out. Could not catch the C&C 44 ahead of us.

Another time I hit 14 knots sailing alone across the Straits of Juan Dr Fuca running with just a #3 jib. Blowing about 40 knots.

Only about 12 knots in this picture.

6 kts on a j24. Okay,  maybe a bit more, but nothing to write home about. 

You should ooch like the pros do.

For what it's worth, I saw one go much, much faster when time the hoist winch freewheeled while hauling out at low tide.

12.5 in a 35 knot puff yesterday on a J/35, under main only, reaching back to the dock in Annapolis from a cancelled race.   We've gone faster under the spinnaker in surfing conditions, ~14.5 or so, but the mainsail-only thing was pretty wild.

2020 Hook Race.  Saturday afternoon.  Outflow from storms.  Blowing 30-40 kts.  Doing steady 12-13 knots boat speed and touching higher.  Saw 16.1 under main only.  J92 Runaway

Highest I saw was 17.2 on the GPS when we had the main and 3 up.

is that a 92 or a 92s?

It’s a 92. Same boat DCBSheb was referring too (he’s one of the owners, I’m a happy helper monkey). It was a wild ride!  The whole thing starts vibrating when you get up on a step.

As is the case with all of the "how fast have you gone" threads - instantaneous GPS speed readouts (doppler) are meaningless. You can often get a spectacular speed readout by moving your gps gadget from one side of the cockpit to the other. To get a reliable speed estimate you need to process the data after the fact to delete erroneous readings (see above) and identify an average speed between two points, even if it is only a hundred yards. This process invariably leads to a much more modest speed estimate than the one on the "max speed" readout of your gadget.

GPS speed is pretty accurate and is actually an average over a 3 sec period......

Unless you have 3 knots of tide.

13.9 knots in this video on the J/46, fun but not hair on fire. She goes faster with the kite up but that’s a lot of work for just a few cruising miles. And yes I know, it’s not really heavy weather, but need clickbait to keep the YouTube algo’s on our side.

No, it is still just as accurate......Speed is relative.  STW will never be the same as SOG, unless you are sailing in a pool.

What he's saying is if you have 3 knots of current behind you, your max BS will read 3 knots greater than what the boat is actually sailing.(or if its against you 3 knots less, or a component of that number if the current is at an angle to your boat)

Current infuenced top end boat speeds don't count.

That being said, most knotmeters aren't accurately calibrated either!
