38' Steel Boat - 30,000 lbs ?

Does that sound right? I have been looking at glass boats around the 37-38' range. Most are around 15-16,000 lbs. Does it sound right that a 38' Roberts would weigh in a 30,000 lbs?

I like the idea of a steel boat but at 30,000 lbs would it be a complete slug to sail?

Are you sure they are 15-16k lbs? And are you sure that the Bruce Roberts is actualy 30k?

A Island Packet 37' vessel is speced out for 24,000 lb. I'm sure once you include crusing gear, they're heavier than that.

A Catalina 387 is speced out to weight 19500 lb.

The plans for the Bruce Roberts Spray 370 on the internet say they're seped for around a 24k displacement. Again, I'm sure they're heavier in service.

So 30k for a vessel that's 1 foot longer, more or less riged for offshore, and might already have gear in it sounds reasonable to me. It still is probably a bit heavy.

There are so many other things that influance how it sails, I would be inclined to take it for a spin before discounting it.

ViribusUnitis: Thanks for the quick reply. Actually I was not discounting it. I was asking more experienced people than myself. It just seemed that 30K sounded heavy. Your point is a good one. Take it for a spin indeed. Unfortunately someone else has already placed and offer. I waited two days too long.

A fully laden warship can weight a lot more than that and still make 30 kts.

Weight is only a factor when getting under way and coming to a halt. The more weight, the more time it takes. But once under way, that weight becomes energy.
Hull shape is whats import.
30'000 lbs if shaped like a torpedo will be fast once up to speed.
15,000 lbs if shaped like a barn door will be slow as a dead pig

Rather than worry too much about gross weight, see whether she is floating reasonably close to designed waterline. On your test sail make sure that there is a stiff breeze and you will get to see if she is too tender ( ie weight too high).

The Roberts Spray 38 in steel weighs in at 29,000 according to his webiste, so your 30,000 lbs is not out of line.

Offshore 38...

If you have a look at the Bruce Roberts Australia website you should be able to get some idea of the weight.

The Offshore 38 has the following specifications:-

L.O.A. 11.66 m 38' 3" L.W.L. 8.38 m 27' 6" Beam 3.43 m 11' 3" Draft 1.70 m 5' 7" Displ. 7,010 kg 15,456 lb Ballast 3,048 kg 6,720 lb Power (Diesel)
20 - 30 h

I have a Murray 33, 33' in steel. Ted Brewer shows her as a little over 13,000 pounds. My PO weighed her on the transport truck, sans rig, at 16.000. I'll bet she is not at 18,000 to 19,000.

I have seen them advertised from 13,000 to 20,000.

So my bet is that you have a more or less accurate weight taken when she was lifted full of cruising gear.
