All up weight for trailer selection

[pete]

Howdy folks, hope everyone is doing well.

Got a question like one of those 'guess the weight of the cake' types you might get at a village fair, just in this case you don't win the item, just massive kudos and perpetual bragging rights instead...

I'm thinking about getting hold of a trailer fairly soon, most seem to be sold based on length and load capacity. Length is easy, but for an all up weight does anyone have any estimations by any chance?

The keel is ok - i.e. weight of steel + lead - 80kgs of steel (ish) and 120kgs of lead (ish).

The hull is a bit of guesswork - i think maybe 400kgs of plywood and then about 100-150kgs of resin and other stuff. Does anyone have any better ideas about this, i'm just eyeballing the stack of plywood and guessing!

Add a mast (Don any ideas/ spec info from the supplier you have made an agreement with for the kit?), sails, deck gear, outboard (can get this from the suppliers websites), liferaft etc and the rest of the required on-board and launching stuff I'm guessing over 1000kgs.

@don - what capacity is the trailer you have for Trekka out of interest? Any special considerations you made when buying?

Given trailers appear to jump in load capacity from, say 750kgs load capacity to 1000kgs to 1250kgs and the jump from 750 to 1250 is quite substantial (like another 1k GBP for some vendors) it would be good to see if others think i'm in the ball park at around 1000kgs all up weight.

There also appears to be some additional cost for trailers rated for the UK and those rated for the EU roads - i have literally no idea what this means, if anyone has any experience of these two ratings please let me know! Taking the boat to another country right now isn't really looking likely (!) but for definite in the future that would be the plan...

Hello,
@don did you weight Trekka now hull finished + the stainless parts we can see on the last picture ?
It will be then easier to guess a final weight.
In Switzerland you dont have different rates for the road - only one yearly sticker at Chf 40.- for trailer + one for the car, for the motorway. Actually no CG580 event in Switzerland!!
In France it is depending if the height and weight of the trailer maybe this link can help www.autoroutes.fr/fr/classification-des-vehicules.htm

The drawing here about 3/4 way down the page says that we'll be somewhere between 2500lb-3300lb or so (depending on how much you like rice cakes).

Good spot - will be going for the slightly more expensive trailer with greater load rating... 1145kgs + some general other crap in there will push me into the heavier bracket, but still well under the max trailer rating (total train weight) for my car. Good news.

Your on the program here and the final decision is up to you based on the car your going to use to tow and it's max capacity and then how much you want to carry in the boat...I was trying to stay with a single axle trailer as easier to move around when NOT connected to a car...but ended up with twin axle...and I think??? cause I gave my spec to Piotr but looks like we ended up with Not the original custom trailer?? should be 1200-1.5....but you need to check in your country about registrations and standards...very important...so ?? good luck

You always need extra cause you do not want to stress the trailer either at max load, so work on 1200kg and your covered...you will carry the boat with extra stuff onboard for sure...so?? round it all out...very simple...probably about 1 Tonne...so go for 1200kg ...Good luck..also check the car towing capacity...etc..

From my experience, two axles make the trailer much more stable and safer on the road, smoother (but less reactive) to manoeuvre when driving back and mostly self balanced when unloaded.
(except if you have a storage ber) most of the time your boat will be stored on your trailer then the weight will be bistributed on four tyres reducing their tiredness.
"The negative" points: make them more expensive to buy and maintain (double of tyres), they are heavier, need more space to manoeuvre when back driving
