I have 18 and do sail solo (and with crew). What are your main concerns? It is really easy boat to handle. And you probably know that people race in Silver rudder solo with 18 and one 18 did R2AK solo. Raising mast needs additional person or a support aft of boat (~2m height). Ramp launching...

Look at WL on PS side. It could be that top of bulb is different from sides and bottom, but I am inclined to optical effect.

I am also slightly sceptical to idea of shorthanding 60 footer for fun. I can understand allure of IMOCA, but even that is way too far for me. As to this ICE 62 targa, I got curios enough to check manufacturers web site. Couple notes what I observed there: - Boat has apparently two retractable...

@sukru This is good solid info. I take you race W/L races mostly, I am a bit supprised to see platus so down the list or are those sailed by more junior crews? I am also a bit curious if you know how different boats would be placed in ORC fleets (A or B)? You seem to have quite tight racing...

I agree that J/70 probably isn't fastest against other similar type boats and in mixed fleet it rarely pays to be slowest boat.

And yet they organise ratings for sportboats that are not intended to operate offshore. I thought that this was context OP asked if J70 is competitive agains other boats with ORC sportboats rules.

@Some.Rando Offshore? Where did that come from? http://www.orcsportsboateuropeans2021.com/  

Exactly. I sail in archipelago and we have loads of small wind shadows (like 50-100m). I have small and light boat. So, some heavier designs just roll with momentum through light patches without doing much whereas even if we shift weight trim sails etc. we get stuck. At times that can be a bit...

@Black Jack I agree that often conditions can make it easier to perform for different boats. The way you describe experience makes me think that you were able to sail closer to your rating in average than your competitors that had to do much more gear changes as conditions were a bit on the...

Now that @Zonker provided one example and rereading @Misbehavin' original post, I might start to see what you are after. We really are interested in upwind performance as that is where most heeling takes place. In short narrow design will heel more than wider design if both have similar sail...

In short, yes. As @Zonker explained that calculation is part of proper VPP. It is just question if this information have been provided as part of output. Now are you looking for a particular vessel or more in general sense this information? If first, I believe checking if boat has ORC...

Have had a bit of exposure to these things. If idea is to utilise wave induce vessel motions to create propulsion, it is important to note that there is certain sweet spot in vessel size due to available wave lengths (and desired speed). So in this sweet spot it can provide quite meaningfull...

Some interesting information regarding this topic by Norwegian insurance company Gard: www.gard.no/web/updates/content/31171690/what-happens-to-containers-lost-overboard-how-long-do-they-float They also mention that they actually do try to recover those lost overboard. Though as we know it is...

@hariboEnergy approach is interesting, but also results in serious headache.. It is all about which control volume you choose. Large enough control volume and the answer is zero (when consider typical boundary conditions). It really about picking right control volume for the losses you are...

Hi, Like indicated, I am not any expert and have been just reading how similar type boats/sailplanes are trimmed from various sources. And then done some testing on water. Twist is important and you really need to get speed first and then pointing. I have found that one really shouldn't close...

Don't know how much there is first hand experience with 27SE or new 27. And I can't either claim experience with these two models, but I do own 18. So, claiming these boats don't go well upwind is maybe slight misconception. They actually do go quite well for their length and point really well...

While I can see this point, I think it has certain feel of luddite. However, what I would put more attention to is how one manages to break two computers in relative short time? Is issue maybe bad quality power feed or pure low cost computers? Could this have been avoided? Even paper charts...

Not really expert either, but have some exposure with container vessels. The 8 is pretty close that you can stack on top of each other. They do actually calculate these, but problem is that those loading containers (this could really anyone) don’t declare correct weight of cargo. So bottom ones...

I wonder if Cristopher Pratt will get chance with Charal. It would seem that Jeremie may have too much going on..

Not very difficult to find, but here is link:
