| I never weighed mine, but aluminium alloy is about a third of the density of galvanised mild steel. Even allowing for wheels and things, and larger diameter tubes its surely going to be in the vague region of half. |

A bit annoying when they bob to the surface and float away from where you want them to be when you're recovering in a shore break.

Just googled it (I know, I need to get a life), 2.7 g/cm3 for ally and 7.7 g/cm3 for steel but you need about 40% more thickness for equivalent strength so about half sounds right. So how much does a Blaze trolly weigh? My guess is 20-25kg for steel so, say, 10-12 for ally......

A lot of steel trolleys are far heavier than they need to be. The Optiparts ali laser trolley weighs in at 11.5 kg inc wheels. Unfortunately it weighs in at £250 or so... Trident say their Laser Trolley is 26kg.

One advantage of steel is that the scrap price is currently only 11p
Kg meaning it's more likely to be under your boat when you arrive on Sunday morning. |

This question was asked on the DZero FB page the other day and Rodney Cobb (Devoti Finn UK) replied, "Steel trolley is 33 Kgs and Aluminium trolley is 20 Kgs, based on Finn trolleys which have the same frame with different cradles." I'm sure you can extrapolate that result for whichever trolley size you are referring to.

We are talking Finn's Rupert, the cradles and bow supports (and presumably Mr Cobb meant same cradle, different frame) probably have to be a tad more substantial than those for an International Moth. Its odd, I've had a bit of a trawl round, and no-on seems to publish the weight of their trolleys.

I don't know what the actual saving was, but it was very significant on my IC. I also like floating trolleys for getting the boat on and off. In my case I was quite sure it was money well spent. |

| In the musto and 49er when you are trying to get sails up and launch on a windy day the weight in the trailer is pretty handy to keep the boat from flying off. I would not want an aluminium trolley in these boats as the weight saving does not get you reduced container costs or transport costs to any measurable value so what is the point. Maybe in a Finn where the boat is so heavy that you want to reduce weight on the shore but in the lighter boats it is not so obvious. |

 Too damn right! I'm going to try this, take the sail, dagger, rudder and any loose bits out of the boat then pull it up a slipway. They probably weigh 10-15kg, the difference between a steel trolly and an ally one. The difference is more obvious in light boats, a Finn is still a big old lump on shore even with 10kg less trolly to haul up the slip....... ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

My H2 which when fully rigged weighs 74kg came on an ali trolley. Its a light boat on a light trolley and as a result can rock around alot when rigging it on the beach in a breeze and the floating trolley gets some getting used too but is really nice when sailing by yourself outside of normal sailing times on a lake as you can more easily launch by myself and easily get the trolley when I get back. Some guys with H2s at my club have a steel trolley and you really do notice it on the slip as a light boat on a light trolley is so easy to drag around! ------------- H2 #115 (sold) H2 145 OK 2082 |

74kgs?
You need to redefine your weight description perception 'light' starts at <50kgs and goes down from there. A Solution is fairly light, as is a Streaker, and the Farr 3.7, the Aero of course, even the D0. anything over 50 kilos is not light and anything 65 kgs or above is heavy. Given that Health and Safety refuses to permit anything over 32kgs being handled by one person, until recently almost the entire dinghy population was in breach of H&S guidelines. Sorry to be a pedant, but weight has always been my biggest gripe about dinghy boats where it is unnecessary in this day and age. And here's a thing, I recently asked to be quoted for a carbon decked streaker like my Farr 3.7.. guess what.. ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

Handled by one person or lifted by one person? I just had a look at the HSE Risk assessment of pushing and pulling (RAPP) tool, and it seemed to me the biggest risk factors are not so much the weight as the environment - slopes, poor surface, obstructions etc). 50-100kg on two wheels scored amber risk, but the average dinghy park is red for obstacles. |

Grumpf - the H2 FULLY RIGGED weighs 74kg. A basic Google search would indicate that the hull weight for the boats you mentioned is as follows: Solution: 56kg d0: 43kg Streaker 48kg Farr 50kg With the exception of the d0 I am willing to bet you that all of those boats weigh more than 74kg when you add the mast, boom, sails, foils etc. Do try and read the post! ------------- H2 #115 (sold) H2 145 OK 2082 |

Picked up on the Finn trolley discussion earlier and I am sure that you can guess that with the Finn being fairly heavy, some would say approaching the gross tonnage of a super tanker, there's a lot of weight in the moulded cradles. Most people who have traded up to an aluminium trolley are very pleased to have 13 Kgs less to move around. Also my trolley dolly is very grateful

Sam the H2 hull is 56kg so yes the rest weighs in at 18kg. Bear in mind the spars are all carbon as are the foils I think you would find that most on that list are >75kg and anything with a tin mast or boom will be significantly heavier! I just think we all imagine that our boats are lighter than they really are. The Farr for example - I assumed that as it is small and made for midgets that it would be light but the hull weighs 50kg!!!!

And 40+kg lighter than my Spice (what it really weighs that is). Bear in mind an epoxy Blaze weighs around 50kg out of the moulds, 72kg is including racks, CB, all fittings and some lead. I'm assuming the H2 weight includes CB and fittings (and, hopefully some lead) so more like 16 kg (or roughly the weight of the racks and tramps)  .------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

While we are on the subject when, if ever, is more weight an advantage in a racing boat? Stability? Momentum in the light (but probably more than made up for by the extra drag and lost acceleration)? ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

Ballast may be advantageous. Weight, well, it depends what you call an advantage. Slow heavy sluggish boats may survive in wind and wave conditions where a fast boat will get the crew into trouble faster than they have the skill to get out of it again. That's all very well, but it means that the crew has to put up with the poor performance in sensible conditions.

Date Posted: 20 Mar 19 at 8:28pm
Well don't we have, on occasion, to do both? I can't understand why anyone can be defensive about unnecessary extra weight, just because of build inefficiency. Let me remind y'all.. It's 2019, we're nearly 2020, carbon prices are at an all time low. I had not a heated, but an 'interesting' discussion over the fact the Streaker dinosaurs would almost certainly refuse my application for a carbon decked Streaker for next winter, not surprising I guess, since they can't even get to grips with a carbon mast, meanwhile I wonder how many ex Streaker sailors have gone for Aero 7s, which totally eradicates their 'expense' argument. None of us are getting any younger, and the biggest ballache is not on the water, it's the humping about on and off the trailer/car roof/ garage floor and don't even talk to me about 21st century Snowflakes who can't even lift a spare wheel never mind change one. If ever there were solid proof of all this it's the tremedous success of the Aero. It's light, that's it's principle USP. Sorry, it's a fact get used to it, and as a 'weighty' class, innovate, adapt or die.

I was hugly excited by the Aero when it first appeared, not that I could afford a new boat of any flavour, but after 30+ years windsurfing I'm well aware of the penalties of light weight (Raceboards that were so fragile that at least a couple of people I know didn't race them at reservoirs 'cos the 'beach' was stony...... even though they were, technically, overweight) I decided that the Aero, while better in so may ways than a L@ser, was not for me. Like iGRF and his Solution I love the Blaze, it's not perfect (but what boat is) but it is light enough that I can pull it up a slipway after a hard days racing and it is a great boat to sail. BTW Graeme, have you considered a Europe? 45kg, Carbon rig, any sailmaker you choose, incredibly tweakable and designed for lightweight sailors, what's not to like ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

The blaze does also have a 10m sail whereas the H2 is at 9.3m plus the H2 width is all hull whereas the Blaze gets a significant amount of its beam from racks so the wetted area of the blaze is smaller than for the H2. The Blaze is faster over the water than the H2 across a range of conditions in my experience of racing against them. I can normally finish ahead of a decent proportion of the blaze helms on the water let alone on handicap at the Great Lakes events but the best guys (like YOU!) are quite a way ahead both on the water as well as on handicap. I think its about right the offset. ------------- H2 #115 (sold) H2 145 OK 2082 |

To float or not to float trolleys, for me depends on the slope of the foreshore. Home sailing is steep and rocky, floating trolley every time, as otherwise the only bit that touches the trolley is the bow and the rest blows around. Nice comfy, easy reservoir slip or sandy shallow foreshore then a sinker works best. ------------- Mistral Div II prototype board, Original Windsurfer, Hornet built'74. |

Safest way in any Lee shore waves is to lift the boat out the water and onto the trolley. At events we have done this with Aero's Phantoms and Musto skiffs I think we also did it with B14's. Light boats certainly make it easier. I have not launched yet with my new Ally trolley so don't know with solid wheels if it will float or not. ------------- Gordon Phantom 1430 |

Blaze is definitely not a low wetted area design, you are right, and it is indeed very stable though it will tend to sit on it's leeward rack if left unattended in any wind.
But that's all I said didn't I?
Given the lack of H2s at either of my clubs that's not likely in the near future but looking at photos online I'd stick by my statement, with the caveat that H2 looks a little narrower at the WL. ------------- Spice 346 "Flat Broke" Blaze 671 "supersonic soap dish" |

The 'hull' can be as wide as you like ... with wings or a 'flare' in the overall hull shape but you do not sail with it fully immersed in the wet stuff. Wings have no effect on waterline (immersed) width !! ... and if you are sailing (flat) neither will any hull flare.

"It's the tyres that wind me up, brand new and already full of cracks." Anyway, trollies. Don't buy new trolley tyres if you can help it; simply fit your old part worn 8" road tyres much tougher so more resistant to punctures and a better quality material to begin with. Works for me. |
Posted By: Granite

I do exactly that too. With a light boat as an additional benefit punctures are not that critical the sidewalls are often stiff enough that you don't need any air in the tires. My current trolly is made from a broken mast and a broken boom with bits of a broken tiller as a handle.

Having just flipped my new boat over it might be a bit lighter than that time for some lead backing on fittings! Gordon 1465 Sea Creature ------------- Gordon Phantom 1430 |

Well my chums Phantom doesn't 'feel' like 61kgs it 'feels' lighter than my Solution when you move it around the beach, it was a Vandercraft version, don't know what they claim to weigh, but it's a devil site less than a Blaze and that's for sure. ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

...... but it's a devil site less than a Blaze and that's for sure. Just as well you don't have one anymore then - nobody likes to imagine you still struggling with one off the water ! ... or for that matter 'on' the water from what we heard.

There is no absolute limit on weight to be lifted by one person. it is routine for one person to handle up to 2500kg loads in the workplace without powered mechanical assistance - the rated capacity of many 'manual' pallet trucks ... |

Well I'll tell that to the baggage handlers next time I travel they are restricted to 25 kgs, it was 32kgs, and once upon a time, I did run a warehouse where, guess what? ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

Thank you for demonstrating your ignorance here Pierre you appear to have made a very large conflation here. |

I work in a warehouse . With anything over 32 kg we are requested to get help but not restricted to doing this . Therefore as we are not given back the time for getting help , everyone lifts them on their own. And this is not in a little back street company, this is in the main warehouse of multi national car manufacturer.

Pipe lagging or a cradle ?
Would a cradle be used for wooden or plastic boats ? |

Any employer will tell you, we live in a litigious H&S age, where staff have all sorts of rights to 'injury at work' claims and we have insurances and have to have risk assessments, lines drawn between what can be lfited with and without mechanical assistance and trust me, you are asking for trouble insisting on staff lifting stuff over the guidelines. Certain things have to be palletised and moved with pallet trucks and fork lifts etc.
Why are we even arguing this, it's a matter of public record, it's also a fact that the maximum weight baggage handlers could lift was reduced from 32 kilos to 25. The reason it doesn't affect us as dinghy sailors is because we do it voluntarily and nobody forces us to do it, but I wouldn't want to be the owner of some plastic tub operating sailing school and or holiday outfit or face the insurance cost. ------------- https://www.corekite.co.uk/snow-accessories-11-c.asp" rel="nofollow - Snow Equipment Deals https://www.corekite.co.uk" rel="nofollow - New Core Kite website |

| The trolley is mechanical assistance though. A well balanced trolley can make the boat almost weightless to lift and decent wheels (not that any seem to exist) will reduce how hard it is to pull (or push). Empty road bases, on the other hand, are back breakingly heavy to lift. |

Exactly Peaky, having injured myself pulling a boat out of the water the trolley makes all the difference. You are not 'lifting' the boat but moving it around. ------------- Paul ---------------------- D-Zero GBR 74 |

| If you think a Blaze is heavy, try helping with a YW Dayboat - just the centreboard (9.5mm steel) weighs as much as some boats and the total weight without trolley is minimum 204.3 kilos. Makes even the Albacore a lightweight in comparison! |

That https://www.optiparts.com/windesign-products/parts-for-laser/windesign-trolleys-for-laser/ex2015-trolley-for-laser/" rel="nofollow - Optiparts trolley sounds like the biz for a Streaker (you could probably shorten it and make it lighter still!). I've seen Admiral steel Streaker trolleys being sold at £295, i.e. dearer. Does anybody have experience of the Optiparts alu trolley? ------------- http://www.wilsoniansc.org.uk" rel="nofollow - Wilsonian SC http://www.3000class.org.uk" rel="nofollow - 3000 Class |
