Default No THT BS, tell me your legit speed

Question for boat owners on 31 to 34 foot boats. What do you cruise at in 3 to 4 seas, 7 second period, 15 knot winds, pretty choppy.

List boat, are you comfortable, are you wet or dry, your speed

The problem you have with this question is no one agrees on wave height. Iíve got a 31 Jupiter. In true 3-4í seas that are wind blown Iím going 25 mph bc the boat doesnt like to go much slower on plane, but I wish it would. But in 2-3í seas that most people call 3-4s, Iím cruising at 30 and could push it higher without discomfort.

3-4 means the average wave is higher than the gunnels and thereís some 5s in there from time to time, which is a chest high wave and plenty to cause a very unpleasant situation.

So what would the true wave height be if you need 10.5' of clearance for the hard top & the top of the waves was higher than the hard top?

25 mph +/- sounds about right for answering OP's question.

Of course, wave direction and winds will also help set speed so if they aren't in our favor your speed will suffer.

And it also all depends on what's about to crawl up your back side, storm wise.

Down wind, 27-28. Chris Craft 328, has a 21 deg deadrise and handled chop really well. Into it, I never did, took the ICW on the way back each time. Gotta know your limitations.

32 blackfin - 24-25 knots. I cruise at 26 so figure the wind and chop slows me down. A true 3 ft doesnít make me throttle back much.

if the boat went faster I wouldnít hesitate to push to 27-28 kt

I honestly donít see any boats my size that ride better.

Are you suggesting that there is BS on THT?

I have an old POS Mako 236 inboard, which is slow as dog crap, but the funny thing is that on the Chesapeake on the windy days I am about as fast as the big 2 or 3 outboard boats.

Depends on my post. About 28 mph in my GW 30' CC. When I am in my Freeman, 90+.

I plane pretty easily and she is a wet boat so honestly the few times that I have encountered that size of waves I am probably only comfortable around 15-18 mph. Visiblility is an issue around Puget Sound, Strait of Juan De Fuca so I am busy looking for wood in the water or other obstacles in addition to not wanting to pound the boat, and passengers. My entry is fairly sharp at 50 degrees but it is only 15 degree dead rise. I am generally not doing long offshore runs and would generally avoid large seas and high winds if possible.

It really depends on whos driving and if they just plow straight ahead or steer with the seas.I think 22 - 26 in those conditions is what its going to give you.

You don't say head, beam or following but I'm going to assume you mean a head sea
3 - 4's with a 7 sec period is spaced pretty far apart
I won't pound my boat so I'd say 20 - 22
Not much spray head on but a little cross wind and the wipers are going full time

Let's see if you can pick through the BS on this one

It must be a NOAA wave height on marine forecast. Let's make it simple

The other factor in this is “comfort”. I have ridden on my neighbors 33 contender in seas that size often and he is evidently comfortable doing low-mid 30s. As his passenger I am not. All I can think of is the bow grabbing a wave and what happens next. I have to think that unless a boat is super heavy or shaped like a knife 20s would be the range for most boats?
