These hulls really shine in 3-5s where others can beat the filling out of your teeth. Keep your bow down and Enjoy your day building confidence in your sled and let us know how it goes.



I watched that video...i'm sure you're a real good dude...but.....
no way was that a 5' head sea ! no way !! 2-3' max,that's it...

boat owners have a common mistake:

speed and ride quality,are often exaggerated !

I have a 23 center console - had a 31 Bertram.i can honestly state,the seacraft rode better !
my seacraft - it would NOT run well in a true 5' tight head sea - ANYONE stating anything different is exaggerating -end of story.
a tight 3'-5' sea - with a wave period of 3 - 4 seconds is a tight chop,a long period 3-5' sea,no problem...again,tighten that up,and you've got problems...

Well I was there and I CAN tell you it was very snotty and kudos to Moose, Melissa and Conner going out in that crap and getting us grouper and hog fish for dinner!! They were the only ones "brave" enough to try it. I must have missed you at that gathering.

The rule of thumb for wave to sea height is 5/9 or 9/5. In other words, if the waves are 9' feet from trough to crest, the sea height is 5'.

So if the WAVES are between 3' and 5' high, the SEAS are between 1.6' and 2.7 feet.

If the SEAS are 3' to 5', then the WAVES are 5.4' to 9' high from trough to crest.
Similarly, 4'-7' seas have waves that are from 7' - 12' high.

Most people think Wave height and Seas are the same thing, they are not. The problem is also that many TV "meteorologists" don't know the difference, either. I've listened to a TV forecast for "waves" to be 2'-4', and gone out only to find out the waves were 4'-7', because the talking head on TV didn't know the difference. I'll go out in a 20' Seafari if the seas are LESS than 3'-5'.

I've been stupid and got caught out off the Juno Ball in a 25' Robalo when the seas were 4'-6', (waves 7'-10') and forecast to fall to 2'-4', (waves 3.6'-7') and instead they INCREASED to 6'-9', (waves 10'-16') and we could no longer safely run back in Jupiter Inlet. We first ran south to Lake Worth Inlet, and then sat offshore for over 4 hours riding into the seas waiting for them to die down before shooting the inlet behind a small freighter.

If NOAA says the SEAS are 3'-5', you need to be aware that the WAVES are significantly higher than that.

In 5' seas, the wave crest is 9' high - usually higher than the the top of your T-top when you're in the bottom of the trough.

Multiply wave height by 5/9 to get seas. Multiply seas by 9/5 to get wave height.

And here is where I get confused with NOAA. I understand the difference in seas and waves, plus there is and additional hooker. NOAA predicts something like the predominate waves, meaning that there are a significant number significantly larger than the height forecast.

Trouble is, it sure doesn't look like it when I get offshore. NOAA 2-3 seas almost never looks like 3-5 foot waves, unless the wind speed is a bunch higher than forecast. As the wind rises over 15 and stays there, NOAA starts to look more reasonable, but still more like wave height than sea height.

How do I measure? My eye level is about 6 ft above water(maybe a bit more) when I'm standing at the wheel. When the boat is in a trough and many of the seas in the distance are just getting over the horizon line, its 6 foot waves. How do the rest of you guys measure?

little sporty yes...5' ?? no way....

"I must have missed you at that gathering." ??? don't recall stating I was there -you recall me making that claim ???

I watched a video - expecting to see a tight 3'-5' head sea - that's not what was on the video...

you were on that boat in the video ?? you tell me,you believe that was a 5' head sea ???


you guys need to get "eye o meter" calibrated,or,ease up on the boasting...

Seas?, Waves? I was there and, at that point in the trip, it was a good 3-5 waves, bigger later on, smaller and a lot shorter earlier. I did not think it was extremely close together, but it sure wasn't a long period swell. Remember, the boat is only going about 14 knots.

I think Pelican has seen some better videos than I have. Videos down here never give a realistic view of the actual conditions, Photos either. Two cases in point, (1) when that video was taken the ocean was one big white cap, wind was really picking up. See any whitecaps in the video? (2) a couple of years ago at the east coast gathering, Blue Heron and I went offshore and our passengers took a bunch of pics, shown on this forum. The forecast was 4-6 ft seas. By my measure, it was a confused but honest (4-6 ft waves), maybe a bit more. The pics don't look even close to that.

I used to be a surfer. 3-5 to means an 8 ft. face to me. Add the two numbers up.

So what is it when I am *on plane* between waves and I can't see over the tops fore or aft? I am 6'1" tall, so my eyeballs are at least 6' above water on plane. Sounds like that's 3-5 foot seas?

I call it spooky in a 20 foot boat.

Did I mention they were breaking? I don't recommend trying it.
