    I've been using swell watch and noaa to decide if I want to take my relatively small (23 ft) boat offshore for blues.
    I didn't go out because the forcasts were for 3 - 5 ft swell Friday & yesterday. Then I read reports from folks who say it is calm & nice. What am I doing wrong (besides not just going)? Any advice would be most welcome!

    It can be 15' but if the swell timing is over 12 seconds apart it won't effect you offshore. Any swell timing of 12-16 seconds is ideal.

    Lately the period of the swell has been spread out which makes for a smooth ride and also helps while spotting kelp I've been taking my 17ft er all over lately.

    South swell usually is not an issue as they typically have the long period. West swell, short period will mess things up. Throw in some wind and you've got a party.

    Ideal? Variable winds at 10 knots or less. Swell at 14 seconds or longer. I have been out in very large swells at 20 second intervals and had no concerns. I have been out in mixed seas with a tight interval and had to really watch what I was doing. I run a 19 foot W/A. I was out Saturday offshore and it was very nice. Winds out of the South suck. So, watch the wind forecast and really pay attention to the swell interval and if a mixed swell is forecasted.

    Swell period should be at least two times the height. Etc 5ft 10s. Fun way to test is look at the forecast, go out, see how it is and turn around if it's too hairy!

    I charge 70-100 miles every time I go out on my 19 foot center console. I agree with everyone above- long duration 14 to 16 seconds or more is great. I dream of the day when I can have a 23 footer running off shore!

    My last trip out was for the yellowtail shootout. Forecasts called for five foot swells st 19 seconds... A little lump at the gate, but pretty much glass all day.

    As others have said, as long as it is long period, you'll never even notice a swell.

    My 17' aquasport striper handles 30 mi offshore no prob!! Love the deep v design for offshore stability!! 17' is a good boat for just enough fuel range to get on the "hot zone", in the warm water months!! (Original post) Long periods are mellow but watch out for wind chop.

    It's more about a combo between the swell, wind, and current.
    If the swell is short period, and the wind is against it, then you get into the steep stuff. 23' is pretty good size if you have decent height on the gunnels. If driven correctly, you should be safe in the average seas we get in SoCal.

    Yes pay attention to the wind. On smaller boats it can make or break your day

    I have a 23 footer and pay most attention to wind . When there has not been any wind for atleast 12 hours , its usually really nice . Duration on swell watch will tell me when its too close together . You can check the actual bouys on noaa and it will tell you the wind wave height . Thats a great tool .

    Time on the water is what you need ! You will figured out your limits cause i promise you that boat can handle more weather then you can. No disrespect but same with my boat. i'll head in way before my boats in any real danger. Sometimes you got to test your limits and you would be surprise on what you can do. And hopefully ride home is down hill to make for a smooth ride home

    Exactly. It's not just the period, but the period in relation to the magnitude.

    A 14 sec period is fine for 5-8' swells....not so much for a 12-14' swell. But 10-12' at 20 sec...perfectly fine.

    Then add wind and multiple swell directions.

    You just got to go out and be prepared for plan B...even if that is going home.
