Displacement weight of a 34ft? Tell me yours!

[Sea Bird]

We're kitting out a 34ft fibre glass Orion with autopilot etc and need to determine the displacement weight. The papers say it's 10 tons but we don't believe it! It would be great to hear from owners with the same spec to find out if it's way off the mark...or not! Thanks in advance...

When mine hangs from the crane at lift-in she is about 13,000 pounds.



About the same at lift-out, too.

Sea Bird...is that a Pacific Seacraft? I see specs at 13500 if so.

Generally, though, most boats actually weigh significantly more than the published numbers...

Registered tonnage and displacement are two different things.

Not sure abut the 34. The Orion 35 displaces 9875 lbs.

My harden45 is Registered at 26 Tons, but the displacement is listed at 32000 pounds or 14.29 Tons. She is considered a Heavy vessel for her size.

Tonnage is a term used in ships which is actuall a volume measurement. While there are several measures (GRT, Net tons, Suez Canal tons, etc.), one common measure is 1 ton = 100 ft3. Maybe that's what the papers meant.

Thanks everyone for replying to my first post. You were all very helpful and the hoisting picture was great Rik!

And as for my forum nam - Sea bird - it simply comes from a combination of two things I love and the fact that I am a Bristish girl learning about life at sea. Currently living in Brazil I like to keep some of my identity!!

Thanks again, I feel like part of the community

I used to operate cranes. The confidence exhibited by all those people in the picture is a little un-nerving. If it fell, lots of people could be hurt. I've seen it happen more than once too.

The confidence probably comes from having a crane twice the size we need, straps at least twice as big and four (count 'em) mechanical engineers with boats in our crew - they keep getting consultants in and they keep upping the "what we need list". I still can't figure how much good that stupid yellow hat is going to do if the boat does fall on me. I'm the guy FARTHEST from the boat.

You think those guys are nuts - how about this one??
