How Safe Are Trawlers in Big Seas ?

It is research and evidence supporting what I say.
You on the other hand have produced nothing.

Enough fighting. Take it outside you two.

Are you suggesting that both scenarios are equal likely?

[markpierce]

Although my trawler is stronger and has a lower center of gravity than nearly every other trawler of its size, it is still a coastal cruiser/gunkholer because the saloon windows are too large and more likely to breakage even though they are "industrial" grade, its gunwales are high so that water from breaking waves could weigh down the boat, and its range of 1000 miles too short.

My thoughts on crossing oceans in a multihull power cruiser;
without sails to help stabilize them in heavy sea they will roll, and you can not add active fins or paravanes to a multihull effectively. They require twin engines, which doubles your chances for problems, and require more fuel.They also do not have space for large fuel and water tanks.
A single hulled boat has much more space available and can be effectively stabilized.
You see power cats used mostly as ferries in coastal use because of their shallow draft and their exceptional stability in moderate seas, but rarely as ocean going vessels.

Mark,
I don't think I ever complimented you on a job well done
Your comments are an important part of the "whole boat success" thing.
Knowing your vessels limits.
That said, I think I would feel more comfortable offshore with you and this boat, than I would with some.

Perhaps you can attempt to explain how a powered cat could capsize?
And then provide examples of one that actually happened?

Waves:

• A breaking wave on the beam, regardless of intentional (poor course by skipper) or accidental (loss of power).
• Broaching on a wave face.

Here's one and here's another, neither says how they ended up inverted though.

I feel I need to address your comment

*Hummingway has no problem with anyone addressing anothers comments as long as attention is paid to civility

I have provide evidence done by independent testers that show a standard width multihull is far less likely to roll /capsize in a breaking beam sea than a monohull.
Sails, They will ADD to the chance of capsize in extreme conditions, not increase stability.
That is why in extreme conditions,both on mono and multi, most people reduce sail until none is up at all, NOT increase it.

and you can not add active fins or paravanes to a multihull effectively.

Why would you need to?

They require twin engines, which doubles your chances for problems,

Or gives you redundancy if you single engine has issues

and require more fuel.

Multihulls generally have smaller engines and lighter weight on more efficient hullshapes.
Logically, they would use less or at least comparable amounts of fuel

They also do not have space for large fuel and water tanks.

All depends on the boat
I can carry more fuel and water than a mates 50ft Palm Beach Monohull powerboat
I carry more fuel and water than a mates 44ft Bavaria
I cant carry as much fuel as an aircraft carrier

A single hulled boat has much more space available

... depending on the boat

they need to be, they are inherently unstable

You see power cats used mostly as ferries in coastal use because of their shallow draft and their exceptional stability in moderate seas, but rarely as ocean going vessels.

Except for the ones that are.

A 23 and a 26 ft , narrow beamed trailerable catamaran are hardly examples of ocean going cruisers anymore then a beach Hobie cat as an example of sailing multihulls as being easily capsized and unsuitable as cruising vessels.

Nice boat. Wouldn't take much to make her ocean ready, some storm shutters, paravanes, larger scuppers, and cut down your rpm's. Beebe has some amazing graphs on rpm's and milage. Cut her down to 5 knts and you can double your range.

Thanks, Blue!

Regardless, my boat did make a transpacific passage, with help:

[sailr69]

I know a Monk 40 sunk when a squall came through at clapperton island in the north channel about 4 years ago, charter vessel from Gore Bay. crew survived.

The original post specified a monohull trawler in the 40-45' range.

Is it safe, at least, to stipulate that very few built-as-yacht trawlers are going to have the range, ballast, or stabilizing systems necessary for transoceanic passages? Can we further stipulate that the few exceptions to this, such as the Nordhavn yachts, are going to be seven-figure pricey?

Seahorse Marine offers several open-ocean trawlers for under a million dollars.
