Yeah, but does your trawler have a hydraulic crane; beat that if you can!

Well the main boom on my mast is raised and lowered with a hydraulic winch and the hoist line by another hydraulic winch. I don't know if that qualifies as a crane or not ??
Sort of hope not as it probably means I need some kind of qualification to run it.

Also, as passage makers go seems light on fuel tankage to me. But the big deal breaker in my world is the galley down. She hates them.
Hi Bryan - I really like look of your boat on avatar. Have pictures? Sorry if I missed them on some other post. - Cheers! Art

If most boat buyers rated what's important in a boat, this would be the ideal result

Most s/d hulls need about 50hp/ton, I think cats need about 30hp to hit 15kts.

I'm going to investigate further, I've never considered a steel cat; it would be very cheap to fabricate with steel at a 20 year low.

We have a steel work cat out here, the Revolution 1. 44' x 23' with twin 330 HP John Deere's, its supposed to cruise at 10 knots. Cost $1m Canadian. Makes little sense to me, but it does have lots of deck space.

Wait until it's afloat before you buy the performance figures. The Revolution was designed by Wartsila in Norway, and sold with a 14 knot service speed. Now the owner's are wondering how to fit bigger engines......

...downhill with a following wind, over a period of at least 30 seconds. Lol.

Here's a serious fishing trawler steel cat:

Don't know, their site only says that it "meets or exceeds" prop type.

HamiltonJet

Nice low maintenance yachts though.

Wow, how about this 9 MTR steel cat with twin 60hp/6.5 tons 12-14kts.....

Pretty looking shape, but it uses 3mm steel plate: you'd have to keep up with the paint maintenence or face rust through disaster!

They only let that number out under duress.....

40 knots is really fast, that's a lot of boat traveling really fast, it's got to take some power. With just over 1000 HP installed, 40 knots will burn something between 45 and 50 usg per hour. For Canadians or Britts, that's 170-190 liters per hour.

Thanks, Tad That's around 3/4 nmpg; and, at 45 gals per hr... nearing 1 nmpg. My Tolly and other similar planing hull boats only get about 1 nmpg at 16 to 17 knots. I'd say not too bad at all for that much weight doing 40 knots on the water.

Presumably while submerged. Which is good because few would want to see it.
