Not meaning to start a war here. I am a cat sailor. Due to health reasons, I need to give up sailing, but not boating.

Have always considered trawlers, but since getting my cat, I have become a huge fan of them. I have never sailed a trawler or power cat, so I don't have any real world experience.

Was hoping that those with experience here could give me the pros and cons, or at least any differences between them.

I am looking in the 35-40' range, coastal cruising, not ocean crossing, and looking to live aboard as a second home for a few weeks at a time. I look at the boat like my summer home, so I need real amenities, real galley, big enough fridge, enough space to both sleep and be apart from others, a desk area etc. etc.

But needs to also be capable of doing 50 to 100 mi days. I like that the cats can do 15-17kts if you want to burn the fuel. I don't know what the motion is through seas is. On a sailing cat, bridgedeck clearance is important in seas, monos don't have that issue.

Also, what is engine noise like. On sailboats, the best part of sailing is when you turn off the engine. But there is no noise isolation, when running with the engines, it is really noisy. I would hope on a trawler/PC this is not the same issue?

So if you have some helpful comments, they are greatly appreciated.
 
Welcome aboard. The power cats have a lot going for them with the smaller power and good fuel efficiency. But one of the main things that we can’t live with is the built in furniture. When we spend long times on the boat we like to be able to sit for hours watching TV or reading a book. With our older backs and the problems we have/had with our backs we like recliners to sit in. So any boat we get has to have loose furniture or the ability to put in loose furniture. I think that you will get used to the constant engine noise if the boat has reasonable sound insulation. The noise is comforting and the lack of noise is a problem...
 
My best friend has a 5-year old Horizon 52 Power Cat with Cummins around 600 hp each as I recall. I have done several trips with him, probably 1000 nms total.

Engine noise is a non-issue.

She cruises at about 18 kts and burns 35 gph which is pretty good for a boat that size (older 60-ft monos will burn 50-60 gph at same speed). She carries 700 gals diesel so range isn't great at pace. He runs her at 9-kts a lot and burns around 8-gph combined, plus generator.

He and I have both done a ton of open ocean miles on 50-70 foot mono trawlers (mostly nordhavn - I used to deliver for many new owners and my friend was my best crew). Ride on the cat is great in flat water and some chop. I've never been in more than 3-ft chop with the cat, but suspect it wouldn't be great - pretty jerky. Also, beam seas are not as smooth as I would have thought. Can't beat it at anchor though.

My friend feels a bit constrained by range even with 700 nms range (to empty). He has no desire to cross oceans or anything either, but 500-miles effective range means he has to plan around fueling too much for his tastes.

His other complaint is exposed props. He's touched twice in the skinny waters of Florida, once did some damage and the repair was steep.

He likes the boat a lot, and it's super comfortable with an amazing aft deck and beautiful grill on the flybridge. But I suspect hell sell it in a few years and get one of the newer Krogan 50s

Personally, I'm much more traditional. I'm intrigued by cats, but would be a purpose-built trawler cat. Forget the names, but there are a couple builders in NZ or Oz that are doing some nice cats with serious range and capabilities, though the interiors are pretty basic which suits me fine.
 
Forgot to mention finding dock space. Definite consideration.
 
Lots of advantages for coastal cruising with power cats. When you get into more extended travel cargo weight and loading becomes more critical. You can't just keep filling empty spaces. Depending on size and engines, maintenance and repair can require a contortionist. Curious to see if there will be more offerings in the future with 4 stroke outboards. While that wouldn't be my choice for offshore cruising, it could have some decided advantages for near coastal / inland cruising.

If I were planning to cruise near coastal above 8 knots, a cat would be under serious consideration.

Think you need to honestly analyze what percentage of your days aboard will be underway. A 40 to 45' trawler may be more spacious when it's being used as a second home. Obviously, which models you look at in each category will have a impact on your impression of spacious.

Appreciate everyone's input so far. Sorry about the sailing term, force of habit from 50 years of doing that...

I was looking at the Fountain Pajot MY 37, if you cruise at about 7kts on a single engine at a time, you get 1200nm range.

A bit concerned about how a trawler or PC operates in seas. In my sailboat, anything under say 5' is non issue, you just sail depending upon where the wind is from. Going from Newport to wherever in the bay in 20kts can be 3-5', that is a standard day, though a bit tough if into it, or for those that get queasy on the beam.

Is this the same for a trawler or PC? Or do you adjust course? When there are 5' seas I normally do not see many of the planing type hulls out there doing 20+ kts.
 
It depends.
5' steep in a 35 to 40' trawler is usually miserable straight on the bow or bow quartering with displacement speeds. Following seas of that size will greatly depend on stern shape, rudder size, and autopilot pump speed. Beam seas will suck without stabilizers (you don't have the mast and sail anymore).

Can't answer your question for a power cat, but am repeatedly told big beam seas are miserable in them.

With my 45' boat (avatar), 5' steep is doable, but only for a couple of hours to get to better conditions. I will do that in bays or sounds, not interested in doing it in the ocean.

The worst we have had our current boat, 41’ President, in was 5 to 7s coming on our starboard quarter crossing Lake Ontario. It wasn’t bad but it was uncomfortable. Better than it would have been on the bow or side. The autopilot did ok but it was working it’s butt off.
 
From OP: "A bit concerned about how a trawler or PC operates in seas. In my sailboat, anything under say 5' is a non issue. Is this the same for a trawler or PC? Or do you adjust course?"

I did the Baja Ha Ha in 2005 on a Willard 40 trawler (no stabilization) - one of four powerboats in a fleet of 160. Roughly 1-week rally covering 1000 nms:

- we averaged almost 7.5 kts and burned about 1.5 gph.

- we were one of the first 10 boats to arrive into the anchorage for each of the three legs (there were a few 50+ foot racing sleds with large crews)

- we arrived rested and in good spirits, unlike about a quarter of the fleet who arrived up to 24 hours later and exhausted.

Sailing is fun, and it's a huge sense of accomplishment to sail into a harbor or across an ocean. But if coastal cruising is your objective and you like the idea of cruising in fuzzy slippers versus foulies, well, trawler (one or two hulls) might be for you - and might make the difference whether your spouse comes along
 
He runs her at 9-kts a lot and burns around 8-gph combined, plus generator.

I'm surprised it's not much much better than that. When we cruise in the neighborhood of 7-8 kts, our tables says we're burning ~ 4 GPH total, with twin Cummins 450Cs. (That's calculated, though, not measured with FloScans or similar.)

Anyway, would have thought a 52' power cat, probably with smaller engines, would be able to better that at speeds up to about 9.5 kts?

Depends on wave length. And then we can "tack" if necessary. And slow down, match speed to wave heights. And we're always fine with a lay day; if weather today isn't comfortable, tomorrow it might be.

My very uneducated guess is that a stabilized trawler might have a gentler (?) roll than a power cat, which might be a bit sharpish (?), in beam seas. I know we (unstabilized, planing hull) can be seriously rocked in beam seas, but then we can usually modify our travel plan accordingly.

As a planing hull guy, beam seas suck due to the fast, sharp roll. A cat may have similar issues there. Head seas can be rough and wet depending on size and steepness and at a certain point, you're forced down to trawler speed anyway to avoid flying off the tops of them.

Following seas (even quartering) can be a bit nerve-wracking at times, but they're easy enough and comfy until they get big enough / fast enough that you can't keep pace with them, then they start to become more work. At 3 feet and not too steep, I can out-run them just fine at a slight quartering angle, it's only a little extra work compared to running with them. Trim up to keep the bow high, and it's just boat slows down a little as you climb each wave and then speeds up as you surf down the front of it. Doing this last weekend on Lake Ontario had me climbing waves anywhere from 13.5 - 14.5 kts and heading down them at 18 - 18.5 with a power and trim setting that would give 15.5 - 16 kts in calm water.
 
IF anchoring out is your thing , there can be a PIA with most any multihull.

Cats or tris are wind born at anchor , where heavier single hulled cruisers are frenquently current born.

All depends on wind or current speed , but it can get exciting at changes..

Our answer , Bahamsas style anchoring , bow and stern anchor lead to bow.
 
Ted, my experience last year on Lake Michigan mirrors your assessment. One day in mid-August with a poor wind forecast we decided to go out and see how our DeFever 44 would fare rather than staying holed up in a lousy port another day. We cleared the breakwater and turned south directly into 5-7 footers. After about 10 minutes into a 40-mile trip we turned back. Coming about 180 degrees brought us into a different world, no noise and the fairly steep swells just pushed us along with not much squirrel action. We were just amazed at the difference. We would have been willing to drive all day like that. On the beam, not so much.

Unless you are in your home port every night, or on the hook, or have deep pockets really consider the cost of transient dockage with a multi hull. Some marinas will charge you for two slips if they don't have a dock end available. Even some dock ends have width restrictions due to the width of the channel.

I have never even been on one but is docking a challenge with all that width ? I can put my trawler into a spot less than a foot wider or longer than my boat but I do use my bow thruster, are thrusters available on cats ?

My Albin is only 36 feet, much shorter than you are interested in but just for comparison my total milage for last summer, including wasted fuel from filter changes, running my genny and idling at the dock and waiting for bridges was 4.5 miles per gallon. Thats less than 2 gph fuel burn .

Love my Albin

Not sure about power cats, but docking my sailing cat is SO much better than a mono. Docking a mono sailboat is like landing on a carrier, basically you hope for a controlled collision. Having bow thrusters helps enormously, without them especially in reverse, you are praying.

On my cat with 2 engines, which i make the boat spin in its own width, it is amazing. I feel like I can be a boat pilot. Spots I have gotten in and out of amaze me. I would have never tried that in a mono. Now the beam is 22, on the motor cats, the beam is like 16, so the engines aren't as wide apart, but still, by putting one is fwd, the other in reverse being say 12' apart must give pretty good control.
 
Its an easy fix.
You simply need a much larger cat.

Not so much.
Sleeps 7 to 8 with only 1 shower, 1 head, and no mention of holding tank size. 400+ gallons of fresh water for 7 and no water maker. 2 small AC units for a boat that size? Engine rooms that look like you need to be a contortionist. Looks like a nautical camping coastal cruiser to me. The only thing that speaks of long distance cruising is the fuel capacity.

Mono sailboats vary enormously in handling under power, but if you've had trouble with them then you will find a mono trawler a handful. A modern mono sailboat hull (fin keel and spade) can be backed under complete control, spun in its own length, etc all without a bow thruster. Most trawlers are much more difficult: no grip on the water, small rudders, very high windage, etc. Which is why nearly all have a bow thruster and a large percentage also a stern thruster.
 
Powercats are no better or worse in sea keeping than trawlers in most recreational boating conditions, just different. With powercats you gain usable accommodation and lose engine room space. Also they are expensive to purchase and to keep in marinas. Monohull trawlers will be inherently worse for maneuverability and stability but you can correct that with thrusters and stabilzers of various sorts.

Powercats built mostly for the charter market will have better accommodation but often worse sea keeping. Most of those hail from France (Fountaine Pajot and Catana) or South Africa (Robertson and Caine etc)
If you want better sea keeping try the Australian designers (Brady or Schionning) or the New Zealanders (Tennant, he designed Domino, or Roger Hill, who designed mine). There is no charter market to speak of down here so these boats are designed for less crew, less protected waters and to anchor virtually every night.
The North American designs like PDQ and Manta lean towards good accommodation with very little cockpit space.
All the above are generalizations and there will be plenty with contrary examples.
Now you have the fun part in deciding which of those compromises are best for you.
 
Thanks. I like the idea of more room. We are looking at coastal cruising, I don't plan on crossing the ocean, so no need for a KK or Nordhaven.

I like the idea that the cats , specifically I have looked at the FP 37 can do 1200nm by using 1 engine at a time at 7kts. However, it can also do 15-20 kts, which can get you somewhere fast.

I am not sure what SD Trawlers would be able to do more than 8kts in the 40' range, and if they could, what their interior room is vs. a cat. My 38' sailing cat has the room of a 45'+ monohull.

We plan on going from the Northeast, Maine, down to FL, maybe cross to Bahamas. Also, if we wanted with good weather, we could do 150 mi days, and by days, I mean daylight. 8kts can only do half that in daylight.
 
Not say’in there isn’t anything good about a cat.

Efficiency re fuel burn.
Stability.

Beyond that it’s mostly fly stuff.

So it’s mostly about speed.
You don’t need a cat for efficiency as even a heavy mono hull can deliver .......
but only at 6 or 7 knots.
So if your time is very limited and you’ve got enough money for fuel a cat will be good .... but re the money for fuel so would a mono hull.

Basically it’s hard to sell cats.

If having the ability to go fast matters for your type of cruising, that pretty much narrows things down to cats, planing monohulls and some of the faster SD monohulls. Any of them can be efficient while going slow. The cat will probably be more efficient when going fast than a fast mono. So it's really down to what boats you find that you like and fit your needs within that realm.

Personally, I love being able to cruise at 17 - 18 kts. I'm not retired, so I generally have limited time to cruise. Yeah, going fast costs more fuel, but if I can crank through certain parts of the trip to get somewhere interesting faster and then slow down to take in the scenery, I get to go more places within my available time.

Such as heading into the NY Canals. From Rochester to Oswego is about a 3 hour run for me up on plane, which means I can get down the Oswego canal on day 1 of a trip. If I were doing 7 kts instead, that 3 hour run would be almost 7.5 hours. So I'd burn most of my first day of the trip before getting to anywhere interesting, rather than getting the boring open-water transit out of the way quickly.

Same thing with going to the Thousand Islands. I can get to the St. Lawrence in 4.5 hours, which means a daylight run to my first interesting destination. At 7 kts, I'd be looking at slogging across the lake for 10.5 hours, plus a bit more to get to a good spot to spend the night. Which means either a very long first day or picking somewhere along the way to stop and having 1 less day in the area before it's time to head back towards home.

Of course, in any fast boat, there are some cruising destinations that will require running slow just for fuel range, even if there's nothing else limiting your speed. In my case with not so efficient big block gas engines, assuming 300 out of my 420 gallons of fuel for range calculation, I can comfortably run 160 - 170 miles on plane before needing a fuel stop. If I slow down to 6.5 - 7 kts, that distance becomes somewhere in the 370 - 420 mile range.
 
There are some really promising powercats on the market but very few that you might find in the 100 -150K range you mentioned in your original post. For efficiency of space, handling and economy, the PDQ 34 is the winner but only the rare example can be had for sub-200K. Closer to $150 but still pretty efficient would be the Fontaine Pajot 37 “Maryland”, which actually is a pretty capable sea boat too, if you don’t mind the creaking and groaning. Both boats can cruise in the mid teens.

The space king at that price point would have to be the three-stateroom Endeavour 36, not quite as efficient or speedy but no argument about it’s live-ability and easier maintenance spaces. Comfortable cruise is more like 12 knots. Consider that all the smaller cats are load-sensitive and their economy advantage vanishes quickly when their hulls are too deep.

Again, for that money, you may find a Scimitar 34 or a Fontaine Pajot Highland 35, but these designs are too tight to offer the space or amenities you noted. For a big more outlay, you could probably find a Leopard 37 owners version, famous for being delivered on their own bottoms from South Africa. They are a bit stark, as they were designed for the charter business, but they’re pretty efficient and a step up in tech. Perhaps a bit better for loading as well. Mid teens cruise no problem.

If fuel burn is important and you want mid teens cruising speed then a light cat is the only answer, especially in the 40 foot range. Some very good production cats have been mentioned, but all a little thirsty by mid teens speed.

But to open up the options how about 16kn at 3nm/g?

As the proverbial old saying goes, "Gentlemen do not go to weather." That applies equally to ladies, and some would say even more so.

On a day-long, miserable but unavoidable upwind slog into short, steep six-foot seas, nature urgently called me away from the helm for a few minutes. As I turned the wheel over to my admittedly inexperienced wife, she asked me how to do what I had been doing for hours. "Steer around the big ones," I advised. "They're all big," she snapped, unamused.

Under power or sail, off the wind is better.

Ohhh, yes! Domino sets the bar high. I've coveted that beautiful big cat for years. That four-foot draft allows her to get in and out of a lot of places while still handling a sea. In thinner water, those protected props afford peace of mind. What's not to like?
 
We chartered a FP37 last year in Florida. We had originally chartered a trawler for some training. It was pulled at the last minute so they let us have The FP for the same price as the much older trawler. With my limited experience, this was our first coastal cruising experience, I can't comment on seakeeping.

it is a good looking, modern boat but it was designed for the charter market which means sacrificing salon and galley area to jam more people down below in the staterooms.

The salon is very cramped. It is claustrophobic for more than 2. The galley is poor with limited storage. We got in some swell in Tampa Bay and I had to hold on to the microwave to keep it from sliding off the counter top because there are no fiddles.

The master head is still a wet head. The master storeroom mattress is up against a wall on both sides.

Engine access is good and not like some cats under a bed. We were really unimpressed with the boat.

I have been on a couple of Endeavour Trawlercats in our search for a boat. The layout is much better for living in them although engine access is under beds and cramped.
