Arne – sorry, I thought it would have just been a click of the button. Still, when you get time, it would be good to see Medium Boy worked out fully – with the Halibut rig of course!
For resin thickener, I have used the fine wood flour salvaged from the collector bag of a belt sander – but only with epoxy, I’ve never used polyester. (Now I want follow Slieve’s experience and try polyester. I’m not epoxified yet, but I dislike the stuff and its expensive).
David – yes, I couldn’t put my finger on it, but Sibling Tender almost looks “cods head mackerel tail” (whereas KISS is quite the opposite, actually more junk-like). Now I am slowly starting to understand that design. I spent some time this evening thinking about it in terms of making a model – clearly there would be more work in it,
Now I would like some more advice – and blunt criticism. I looked at a video this evening of a Bolger Brick (8’x4’) sailing under a flat junk rig.

You want to skip the first 25% of it. Its tootling along, demonstrating reefing etc. It seemed to sail moderately well, which kind of validates what I have tended to believe, that at 8’ just about any shape will do.
This has got me thinking again about the NZScow – not as an entry, its not suitable - but simply as an experiment, or at least a topic for discussion here. I am sure it would sail and row at least as well (if not better) than a Bolger Brick.
For a tiny vessel, I think it has a better bow than either a stem dinghy or a pram dinghy.
Its initial stability would be very high. As for the rest of it, I really don’t know.
The Bolger Brick tells me that it ought to heel a little and sail on its chine as well as any other 3-plank. As for initial stability, and load carrying capacity, it ought to be up there with the best. Lofting and construction can be very simple (I know that much already). Its flat and flabby sections mean it might need to be built a little heavier than a conventional dinghy.
I’ve looked at the run and the sheer line of Sibling Tender, and its proportions – and had another go at trying to cobble together a NZscow dinghy. I’m not looking for anything other than bunt criticism – do you see any particular virtues or vices?
