I love this thread. One of the first honest threads in a long time (so far)?
When we owned two yachts, we lived aboard our Moody 33 ocean crosser and we used our Jenneau 36.2 as our sailing school yacht, brilliant giant dinghy. ??I guess I must be one of the few who have had both a contessa 32 and a pogo 2.
All the stereotypes totally true - contessa virtually never slams (but no faster in bad chop than the pogo).
Pogo slams badly upwind but blisteringly fast as soon as you drop away on the angles. And awful for accommodation
The only option is to own several boats to cope with all situations !
You don't even need to be 30degs off the wind. Motoring with a hard sheeted main at 20degs vastly improved comfort?Don't understand why people are talking about motoring directly into the wind. Surely a well reefed main sheeted in hard and motor-sailing at 30 degrees to the wind would be much more comfortable in any boat.
My preference is about 20 degrees to the true wind, with the main reefed to keep the angle of heel to below the 15 maximum that my engine allows. There are occasions where this is not possible though, as when we met an un-forecast blow when coming out of the Roompot and only a relatively narrow channel with 3-4 knots current under us. Sometimes you just have to soldier on.You don't even need to be 30degs off the wind. Motoring with a hard sheeted main at 20degs vastly improved comfort?
Mostly, because I can.Don't understand why people are talking about motoring directly into the wind. Surely a well reefed main sheeted in hard and motor-sailing at 30 degrees to the wind would be much more comfortable in any boat.
The later generation of boats have much finer entries that those of 20 yrs ago. Whatever their other failings, this is a great advantage when going to windward, under power or sail or both. Many of them seem to sit 'on' the water rather than 'in' it and in brisk conditions this can be remarkably effective as they seem to brush the waves aside rather than plough through them, as far as my observations of them go.I do think this is interesting.
I guess I was hoping that clever modern design would have addressed the issue: how can lighter more voluminous boats go to windward in disturbed seas? But from what everyone has said, that’s not really the case. The higher volume builders are making boats that are optimised for sunshine and light winds, but don’t go well to weather in anything other than smooth water. The high performance boats can win races, but probably by cracking off a bit and speeding up, and they require a lot of crew input.
It makes sense I guess. Physics is physics.
And people’s expectations are probably different, for a lot of different reasons.
Also, we do have much better weather forecasts these days, mostly. So the chances of getting caught out are less.
I think Tranona is right, there is limited demand for boats that can sail well in more demanding conditions so they aren’t built very much and the ones that are being built are probably not massively different from designs that date back decades.
hey ho.
what do you think? Nicholson 31, 32 or 35 hehehe?
Not sure I would agree on modern boats have finer entries. They certainly have a flatter. Forefoot than older designs. They slam instead of pitch.The later generation of boats have much finer entries that those of 20 yrs ago.

Interesting. My yacht designer friend says that modern vertical stem designs tend to have move volume in their bow area to compensate for the lack of reserve buoyancy that is common on older designs with large overhangs.While entrance angles are influenced much by the flavour of the day, it is a fact that the divergent wave system leaves the hull at an angle of 19degr 28'.
Notably, my tub, which according to the design brief had her entry angles refined, has the same entrance angle as a Sagitta 35 (SS 34) which is 19 1/3 degr.
I sailed a R. Clark 43 some 1500 miles to windward upon leaving the Hawaiian Islands and while she did not slam, she did sail at startling angles of heel which made living aboard, well, interesting. Her waterlines at the bow were remarkably blunt, in the old British cod's head mackerel tail tradition, yet the long bow overhang kept most of the wet of the decks. It should be noted that the length beam ratios at the time of her conception were much higher than they currently are and this provides a lot less frontal projection and, given the displacements at the time, a much higher water plane loading, which in turn equates to comfort.
Also, the IOR creations had extremely pinched ends, fostered by the rules which led to very fine bows and narrow sterns with fat bellies (eagerly adopted by the cruising crowd) and bred a whole crop of boats with poor behaviour, especially downwind.
If one were to simply extend the current wedge shapes to have a more "traditional" form, I suspect one would find that entry angles are no finer than what one is used to and one could argue that the current variants just have more bow in relationship to their length/beam.
Meanwhile, now that we have given up optimizing windward performance, we have ocean-going blunt-ended racing scows that must just be hell going to weather in anything of a chop and for those who like sailing with a tooth guard and a helmet, the French now offer cruising versions, lauded for their remarkable interior volume in any given length.
Traditional Dutch working craft have super bluff bows and these boats, gaff rig, lee boards and generous displacement not withstanding, will happily put to shame, and on any point of sail, many of their pointy ended, modern sisters... in flat water that is.

Well. to be fair, in much the same way as one might end up with a child when expecting it the least, but you still learn to love it and bring it up to be a balanced and well performing adult.I'd be interested to hear why you chose the boat (hull) that you did - perhaps 5 main reasons or so??
If you look at the current offerings, the entries are much finer than the Oceanis/Bavs of the early 2000s, where the forward sections were filled out for more accommodation. Other changes do include a shallow or absent forefoot, plumb bows and very wide sterns but at least the entries look kinder than of old.Not sure I would agree on modern boats have finer entries. They certainly have a flatter. Forefoot than older designs. They slam instead of pitch.
The entry on our Van de Stadt is fine and fairly common on a Van de Stadt as they have always been a more performance oriented design house.
Our most memorable recent foray to windward was last June crossing the pond West to East with 48 hrs of headwinds over 20kts True, gusting up to 28kts. Two reefs in the main and full working jib. Not pleasant at all. No slamming but a lot of wave impact on the hull sides as we were well healed in about a 2-2.5m chop.
No option to motorsail so you just get on with it.
Hard to sleep but when you get tired enough in it does happen.

We had really been looking for a boat to simply get us a cross the Channel and into the nearest French canal. A roof over our heads seemed a sensible solution at the time, as did the ability to motor against river currents, combined with shallow draft and sufficient displacement to comfortably carry the amount of junk and tools we tend to collect.
Alas, ambitions change and we decided we still liked sailing too much and to postpone the canal business to a later date and explore the European coast line instead.
Unfortunately, as designed our CW didn't really sail all that well even though ours already had 1/3 more SA than the standard model. Her worst feature was by far her steering which under sail could be most charitably described as sluggish and unreliable in as much as the rudder would stall out at the least provocation and leave us without steerage and, at times, dangerously so.
We could have sold her then, but by that time I had already invested a fair bit of effort into her and we loved the pilothouse. I have designed and built a number of boats, including a 50' o.D twin engine & rudder, lifting keel cruising cutter and have sailed and worked on a fair variety of other types. I was not ready to give up and I was sure I could, at the very least, improve her and this is exactly what we did.
So, while I can't say we chose her for specific qualities, I can say, and to some degree quantify in numbers, which of her evolved qualities I like or have grown to appreciate and how they compare to other types I have sailed.
1) Seaworthiness. She has to be the driest boat I have ever sailed on. I used to joke that the only way to get water on her decks was with a bucket, Having driven her into the face of a F8 with breaking seas, I'm ready to modify that statement somewhat to say we've never had solid water on deck. She has an extremely buoyant hull with high freeboard and tall flaired bows. The flair will increase resistance in high waves to slow us down, but we have never ever put her nose through a wave, which is more than I can say for any other type I have sailed on and not for want of trying either. We have really put her through the wringer on many occasions and she has never disappointed our trust or given us any concern. Her motion, due to her bouyancy can be a bit lively at times. Downwind however, she is remarkably stable and rolls very little, even when driven hard under spinnaker and at or above hull speed. I have sailed another, by a famous designer that would roll through a 100degr at the drop of a hat.
2) Shallow draft. I have to confess, I am a bit spoiled in this respect. My 50 footer drew 1.2m with the keel up - I took her through the French canals and visited harbours in the Baltic where the next largest boat was 26' long. At 1.34m with our current boat we were still able to revisit some of those places a couple of years ago. With a lateral plane of 12.9% of SA she still has enough area under water to ensure reasonable progress to weather. As lift is a function to the square of the speed, it helps to keep her moving briskly.
3) Stability. Compared to other motorsailers of her type she has rather firm bilges and lots of beam. Combined with a ballast ratio of 37% she can carry a, for a 31.5' footer, large SA up to a F6. AVS, providing the green house is still there when that happens and we managed to close the door, should be in the neighbourhood of 180 degr.
4) Directional stability. We have a traditional long keel with a fair degree of drag and a deep forefoot. She is directionaliy quite stable without requiring a lot of attention at the helm. Our ancient & somewhat lethargic first generation wheel pilot has no problem keeping course downwind and in a steep quartering sea. Having fairly well balanced ends with decent bouyancy and a centre of lateral plane that is slightly behind the CoG helps.
5)Speed. This may appear to be an oxymoron in context of a Colvic Watson, but we seem to do alright. We now have a SA/displ ratio of 17.8. and the boat has a prismatic coefficient of 0.6 which shows that her optimum relative speed is 1.25 or in our case about 6.6kts. The comparison to a more common CP of 0.54 shows that at this speed our resistance is about 15% less. In practice we have found that we frequently, average 6 kts on passage as indeed we did over 210 miles and even 6.8 kts over 70 miles. There is a penalty for a high CP, of course, and that is at low speeds and when going to weather with a blunt(er) nose.
6) Displacement ... is the real measure of the size of a boat and there is no doubt that weight provides the necessary inertia to counter the effects of the sea and to render them (more) benign. It also provides the volume to load her up for cruising. And of course, you get to pay for that in ultimate speed over and above traditional hull speed.
