Default 3 Foot Seas, 4 Second Intervals - What to Expect

My plan has been to take my boat 20 miles down the Jersey shore tomorrow from a temporary marina to my home marina. Checking tomorrow's forecast, they're showing 3 foot seas with 4 second intervals. I don't recall seeing seas and intervals so close before. What should I be expecting? I hate to cancel as I have a deckhand lined up to assist, but would do so in the name of safety.

I have some good boating experience, but I haven't skippered a boat in this sea state before. Oh, I have a 22 foot WA with a 200 HP yamaha if that makes any difference.

thanks!

A true 3' at 4 seconds is an ass-kicking on a 30-footer, you would get pummeled in a 22.

You sure that's not the offshore forecast? Looks a lot better than that off Jersey tomorrow

I would not do it. Would be a miserable ride and borderline dangerous if true 3 footers and a problem occurred while out there.

That would be painful. I like a period 3 times the dominant height; still go sometimes when it is not and usually regret it. That rule takes a lot of days out but there is a price. I don't think what you are looking at is necessarily unsafe - that really depends on the captain. The wind has a lot to do with this as well. If I have a north wind plus those conditions it is no go. Obviously just my opinion and hope you have a great day if you go.

We get super fast dominant periods like that in the Gulf very regularly and it’s a wash machine. It’s especially bad when those 3s grow to 5s and not a place for any boat that starts with 2.

It would not only be miserable, but it would take you hours to make that 20 miles. If it has to be done on that day, use a trailer.

Use Windfinder app, doesn't look as bad to me.

2.3 - 2.6ft wave height with 8-9 sec period

I live in NJ. Checking Fishweather (my most accurate source), and Buoyweather (second best) the morning is a disaster up until around Noon. Blowing strong out of the NE, and there are small craft warnings in the AM. Then it lays down beautifully and lasts (inshore) all through Sunday.

it still might be a little sketchy to him if he has never been out in anything like that before. as all have said the weather looks fine. Just run out the inlet maybe 2 miles as closer to the beach will be more rough. Or take the ICW. It will take longer, but given the size boat, could be enjoyable, take the wife with you. I can mark any area south of Brigantine for you on a map if you would like.

that's amazing you would do that. Would love to see it! We may just move our departure time up to noon or 1:00 depending on the forecasts in the AM, but this is a great contingency plan. thanks!

With a 22' boat, why can't you run that trip on the inside?
From Atlantic City to Avalon isn't very far on the intercoastal and would probably take you less time inside than in 3' following seas.
Download NOAA chart 12316 from the NOAA website to see the route - it zigs and zags a fair bit, but is very straight forward.

that's what it's like when the wind is blowing at 15kts in the norther GOM.

I've fished in that on my 222CCP, it was miserable, could only do like 15-20kts will the tabs down and we still got our butts beat.

Expect complete mayhem.

If you are in a 22' boat no reason to run that in the ocean. Take the inside down, should be absolutely no problem in a 22 foot boat.
