LMAO. ....Thank you kindly Hum3........now go back through this thread or indeed the forum in general and fix the other similar recent posts....if it was all edited out there'd be bugger all left ....when in rome. If I felt inclined to go off topic I'd argue from logic and reason the basis for my echoing of yellowwellies statement. FACT Edited by transient - 25 Jul 13 at 11:54am |

FACT is, forums are full of OPINIONS not FACT...
anyway, on a beach cat for messing around, I do hope it does have an asymmetric.... let's be honest, it would be pretty dull without one. This isn't positioning itself down the A-Class end of the cat spectrum.... more Topaz 16 CX... but a bit nicer (hopefully). Anyway, back to thermoplastics.... I want to hear more from Peaky/Al etc that's reason why I shoved this multihull (phlegms on pavement) is in the dinghy development section.

The 'fix' was more a reflection of my own view, rather than a comment on the opinionated nature of the post.
BUT ANYWAY...
Anyone got anything interesting to add to this thread about this Cat thing before it turns into a mess of hijacks, tangents, and trolling? Or is it already too late...

Assy sailing is no more or less tactical than the converse; it is just the gains (and losses) are accentuated by the bigger angles sailed downwind. So it is more obvious. There is an argument that with the greater angles sailed that provided greater tactical choice which is true.

I'm sure there was a comment from RS on FB that there will be different variants of the cat from single main to twin trap with assy.
I think it'll go down well, there's plenty of people in the summer sailing clubs that roll out there boat for two weeks of the year and go sailing with no hassle of maintanance. Could sell well over in Anglesey where you can blast round to each seaside resort and beach it with no worries to get an ice cream ;-) |

Depends on what specific tactics you are talking about.... I lost out greatly in some boat-on-boat action last night downwind. Leading a small pack of three, one guy comes to make his move to windward, I luff, with hindsight too conservatively; indadvertedly letting the other guy through. The bloke I luffed then has water at the mark... drop from 2nd (which I gained at the last mark rounding) down to 4th. If the course was another lap maybe I'd have got it back, or maybe I'd have dropped down to last, the guy behind us all was catching up rapidly as we had a proper race..... it's far less predictable (therefore more tactical in a club race RTC environment) than 'banging the starboard corner' on a true run or drag racing and hoping a gust doesn't force you too far off the rhumline and need to drop the rag on a reaching leg. Considering this was in a class which doesn't even enable running by the lee, which opens up even more tactical options, then I really struggle with the 'more tactical' marketing jargon of asymmetric sailing.... that sh*t came out in the 90's. Twenty years later and I think some of us are a little wiser than we once were.

Read Kirkegaard and his ideas on a "Leap of Faith". Personally I'm an atheist but his ideas can be applied elsewhere. and yes a beach cat without an assy would be a bit dull...and yes if stuffed in the multihull forum it probably wouldn't have gotten much traction. |

Most boat builders, understandably, prefer to use materials they are familar and comfortable working with, but that doesn't make them the best choice.
I'm sure Al knows more than I do, but IMHO boat building has created rod for its own back by marketing epoxy/foam/carbon as the de facto ultimate material combo. Of course, there are applications where this is the best choice - a 14 or Moth wouldn't be competitive with these high quality materials. But in most day-to-day apllications 'lesser' materials will suffice to the extent that there would be virtually no degradation of performance, but with the advantages of reduced cost and increased robustness. This kind of cat, for example, will run low rig tension and make no attempt to plane. Stiffness and weight are therefore not of paramount importance, so even in rotomolded form will probably be quicker than an 800 and shed loads more robust and lower maintenance. And heaps cheaper. All good reasons for buying one. There is a growing gulf between high end epoxy built boats and basic rotomolds. Standard polyester GRP sits in this gap, but there is an alternative that will surely replace them. Reinforced thermoplastics offer the potential for the robustness of rotomolded plastic boats but with the stiffness and weight of normal thermoset boats. And, they are recyclable and don't release VOCs when curing. The reinforcing fibres can be short, long or continuous. The longer the fibre, the better the mechanical performance, but short fibres mean the plastic can be injection molded so very automated production and low labour intensity. The plastic can be anything from polypropylene to PEEK, and the reinforcement anything from glass to carbon, so a wide range of material properties can be achieved. This stuff is widely and increasingly used in the automotive and aerospace industries, so is well proven. The downside is tooling costs are higher than for GRP as the plastic needs to be heated to about 200C. Twintex is one such material, essentially a prepreg cloth of glass and polypropylene that can be draped and used much like a carbon/epoxy prepreg. Cleaner, greener, healthier to work with, more bump proof when sailing and recycled at the end of life. And I believe the polypropylene doesn't soak up water, unlike polyester, so shouldn't get heavier with age. Thermoplastics have many advantages for boats and they won't stay at the very basic level they are being used at currently. |
