Why do you guys like monohulls so much?

this includes the fluxgate compass sensor. guess i'm assuming that everyone who wants an autopilot already has wind instruments (maybe fair assumption / maybe not ?)

this compares pretty well with 5000 euro + for a wind vane !

cheers,

My recollection was the Raymarine wheel pilot was less than lowest cost B&G, but I want the B&G. I have had two ST4000s and they are good for holding a course and auto tacking but not some of the more advanced things. But if you are on a budget buy a used Raymarine wheel pilot.

I don’t have a windvane but I don’t do ocean crossings. If I did I might get a windvane. IMHO autopilot and windvane are different tools. For coastal cruising especially single handed an autopilot is a must. I couldn’t use a windvane the way I use an autopilot for sail changes, small course changes, auto tacking etc. Autopilot is basic safety equipment for me for many reasons.

I would say get an autopilot. Then if you are doing long crossings and are concerned about battery get a windvane.

So ideal for trade winds etc.
Performance cats- different altogether

Yes there are slow ones, and ones that are sailed poorly but the max speeds on the ones I was on were definitely faster than my monohulls. Nonetheless I won’t ever buy a cat. If i care about speed I have a bayliner that goes 28kts. I don’t sail to get places quickly except on delivery

Right- there are “max speeds” but why matters on passage is average speed. Sure I’ve hit 14 knots in my mono but usually average around 6 or more knots on my coastal passages, mainly because my boat keeps moving in the light stuff.

Besides the lack of affordable berthing for a catamaran, how would you manage to heat up one during winter? It would be like three boats..

This is a big drawback of these boats. I concur.

Eberspacher 10.5 KW and 4 matrix heaters one in each corner. Most cats are sandwich, ours is foam so insulation is excellent. Leave the cabin doors open and it doesn't take too long for the heat to rise up on the bridgedeck, the whole boat to heats up, the thermostats kick in and you are comfy inside with snow on the decks.

Having spent a winter getting down into the 20's F, this is actually a mixed bag.

At night, it does get colder but we like to sleep in a cold room and burrow into the blankets, so except on the coldest nights, not an issue.

During the day, the greenhouse effect quickly warms up the cabin once the sun is up. It was common for 40F outside and 65F inside with the heater off.

By contrast our friends in a monohull had the heater running less at night but it needed to run during the day as the sun didn't heat up cabin much.

This was on a Gemini which is not a cored hull, so really a worst case scenario for insulation.

My mono is also sandwhich. Couldn't justify burning fuel to warm up three times more and the winter is six months here and heating is required at least 10 months most years..

So it is really down to cost. Yes, multihulls are more expensive in all respects than monohulls.

Don't know cats but my Crowther trimaran just the diesel cook stove did an excellent job and always had fresh bread in a toasty cabin .

Tri would be about perfect, except the wide berths which are not generally available here (=Nordic countries), nor much anywhere by Atlantic side of Europe. Pier sides are but due >3m tides and rude construction they have high risk of damaging the boat..

cheers,

I have a Raymarine autopilot and a Monitor windvane. Had them both for many years. When I bought them the Raymarine was more than the Monitor. Both have required repairs or replacement over the years but the Raymarine has required more expenditure than the Monitor and I carry a spare Raymarine drive unit but no spare for the Montor, though (it has been reliable).

The lower priced Raymarine is simply not robust enough for my boat. Using it in heavy winds and big seas causes the motor to wear out quite rapidly (I'm on my third or fouth drive unit). Now I use it for motoring or very light winds.

The Monitor is very robust and handles all sea and wind conditions and we trust it not to break although we've blown up blocks a few times and broken control lines. After 15 years we had it strengthened further. Now I view it as bullet proof.

I think that the prices you link to are a bit low.

C.H. Smith Marine and Raymarine both show a partial Raymarine system. Both link to a kit with a hydraulic pump but no cylinder or other method to connect to the quadrant. Don't you need a hydraulic cylinder? The wheel drive version is not "below deck" and in my view, is not substantial enough for a passage making yacht. Add a control head for the Raymarine price. With a control head, but without a cylinder or hoses, wiring or installation, the price is over $3000. All up I'd say it compares with a Monitor price of $5000 (or $4500 for my boat).

Then, with an auto pilot do you entertain the need for a spare? Many people do.

By the Jefa linear arm. Much better then the ray marine one

Not they Raymarine type I/ or 2 is best electric linear arm last 30+ year i think is not change anything.
hydraulic i think is best france Lecomble & Schmitt.

[more]

for example cat 45-50ft or to 60 ft mono
Lecomble and Schmitt Linear Pump 50ST20 kit 1500€ with tax 1800
Garmin GHP Reactor 40 - Universal kit 1050€ with tax 1300€

https://busse-yachtshop.de/s/Garmin-...49-mit-Display
https://www.nootica.com/lecomble-and...mp-50st20.html

normally all this is possible find cheaper.
last winter i pay this Garmin GHP Reactor 40 900€ + 25€ shipping with tax. only tax is 19% of this price.
for this setup thrust is 700Kg how much thrust windwane have. couple kg

and for power usage always sensitive can adjust to 7-8. windwane have sensitive 7000 thousand. from course Croatia- Italy you don't know if you finish in Egipt,Greec ,or return to some spot you come,but 100% you don't come to Italy
