Here's a few more tiny junk rigs

Magazine 79 (referred to by Kevin) actually has a feature on dinghies with junk rigs

There's a range of different types there.

For your Selway Fisher dinghy, the mast position for the gunter sloop would look to be about right, though a little taller, and not raking aft would be better.  It's then a matter of designing a sail which has its geometric centre (CoE) about in the same place as the sloop. It's not all that critical in my opinion, as a dinghy with a centreboard (which can be adjusted), and crew weight position being moveable, a little dinghy can be made to balance easily enough and is pretty tolerant of where the rig is placed. The other mast position (for the sprit sail) would also do if it suits you better. Pay attention to the stern and allow for sheeting. If there is difficulty you could add a boomkin, but it may not be necessary.

Here's a few more:

Herb Mc's "Peking Duck" (a PD "racer") has a tiny, full detail, junk rig. (It looks like a "Johanna" or modified Hasler McLeod sail).  

But a dinghy sail can be simpler than this. For example:

Paul Th designed a brilliant sail for Marcus's little boat, a simple little fanned type.

Here's Blueberry, a simple Hasler McLeod (featured in the Boat of the month gallery, scroll back to March 2024)

Here's Skib (Jan W?) I think this is a "Halibut" rig designed by Arne. Can't get simpler than that.

And here's a flat top SJR - Jan Cz.

It's probably time we did another magazine article on dinghies.

Hi, I have never sailed before and am starting to build a Selway-Fisher dinghy (the Surf 8, an 8 foot ply and epoxy dingy) which I plan to use to try and learn how to sail. I figured the junk rig seems easy to use and would like to use it on the dinghy.

The Surf 8 plans come with plans for ' the single sprit main rig ' and 'gunter sloop rig' and a centerboard or daggerboard option. I see these rigs have the mast in different positions. I'd appreciate it if someone could point me in the right direction to get information on where I should position the mast for a junk rig (or could I use one of the current positions?) so I can accommodate this as I build the dinghy. I guess I'd need to know the dimensions of the mast and therefore the design of the sail too so any help in getting information on these would also be helpful.

Thanks in advance
