I put trap wires on a Blaze? In my quest for a middle of the road single hand trapeze boat. Since they won't make me a light Contender, the Blaze is a bit lighter, not light enough by far, but better, maybe ditch the racks? What do we think as a collective? I know it goes against your class sensibilities any thought of customising the dross we have to deal with, but humour me here?

Could it work, what would the issues be?

Would the mast take the forces applied in the different area?

It has been done before* and I actually have all the bits to do this but I haven't got around to it yet. And I have had a kite rigged on my Blaze. Maybe this summer I'll get them both on there together. I won't be risking it with the carbon stick, mostly 'cos I don't want to drill it for the extra fixings but the M7 is a sturdy old beast. A nice new Blaze mk4 hull with racks ditched would weigh around 60kg or a little less IIRC. If you went for the carbon mast you'd save another 2.5kg, dyneema standing rigging, another 2kg or so and you'd be down around 75kg all in. There's no appetite for it at class level but for handicap racing why not.

The Blaze is basically a Buzz / ISO / Spice hull form. So dog slow in light wind due to the wetted surface. Way more than the 3.7. I'd debate Sam's hull weight estimation (but as you know you could make a 3.7 down to 30kg). My view would be that a Blaze would be OK when it's windy for a newbie trapeze sailor, but not very lively, which is fine for a newbie but you are beyond that now, and a 3.7 is way more lively and involving. Can't see how it would bring you light wind banditry.

You are still better off with a fat head main on your Farr 3.7 (with Asymmetric).

Or just by an RS700.

Why not just get a Musto Skiff; much lighter at 82.5kgs all up ...

If you want to make your own based on an existing hull a Phantom might be better.

Well I've ordered a new sail for the Farr 3.7, that is in progress, but I don't think there is a sail made that will undo the waterline length issues v Laser/Aero 7 offwind unless it's full planing hiking, but I do think the Blaze in medium wind with a wire (which keeps me in practise) will remove Lasers and the like from my horizon. We shall see, It's a tin rig, my old one returned for the summer I should be able to sail it better than I did ten years ago when I first got it. From memory it have carbon racks so they don't weight much and I haven't ascertained wether a carbon rig would suit that particular purpose.

Very rough estimate TBF, bare hull around 48-50kg* plus some slate blocks, mast and rigging 7.8kg, sail ~4kg, CB 6kg, rudder 6kg boom ropes blocks, say 10kg so maybe 85kg would be closer sans racks.

* source :- Cirrus but from memory.

The carbon outers save a couple of kg tops over ally I'd say, remember the other 8 rack tubes (two each aft inner, aft outer, forward inner, forward outer) probably make up a fair bit of the weight.

Keep us posted iRGF, it'll be interesting to hear how you get on.

I'm quite inspired by the French dude, he's kited it as well, can't see my lot wearing me fully wiring off the racks and a kite at the new 1033 PY, I can hear the howls and wails from here..

I'm confused as to why you are not converting your 3.7 to a 3.7 Turbo (with Asymmetric). The deep off-wind legs are your 3.7 PY killer.
