Siren 17

I just bought a Siren 17.
The former owner didn't understand much about how she ought to be rigged.
I can't make much sense of how to rig the mainsheet.
It appears the line from the boom would lead to a small block on the port side of the stern, then to a block on starboard with a cam cleat.
Thus it appears the boom will always have a port bias.
Doesn't seem right.

Secondly, the two bolts at the forward end of the "swing keel" confuse me.
Why are there two?

Finally, I'm not familiar with roller furling jibs.
The seller told me the roller furling jib luff takes the place of the forestay.
Can this be true?

Congrats on the new boat.
Yes the furler does take the place of the forestay. As far as the mainsail, it seems there are a couple of different setups. Here is what I have seen on our dock:
Mid boom sheeting, with the mainsheet led to a swivel block on the cockpit sole...

and boom-end sheeting:

It's 5 o'clock somewhere:

I have been sailing my siren for the first summer and towards the end my father and I feel that we have figured out some nice features. First The swing keel upper bolt is a lock pin, on ours I had to drag a rope under the boat and pull to get it to lock in place. (That may not be you need to do with yours.) Second the cushions inside come out to sit on while sailing, these are great on long days. Also I feel that the boom end sheeting is the best because it makes the boat feel a little bigger but if your flying solo rock it out on the sole. The boom on ours was too low on the mast and we moved it up so that the sail almost touched the top of the mast and it made a ton more head room.

There is not a ton of info out there for these so I hope this helps. It is everything that I have learned over the course of a summer. Most importantly lock the keel in place and if it is your first time learning to sail buy a heel gauge for about 10 bucks and learn that the boat heels really nice and if your new it feels like a lot more that it is. I run mine in high winds about 20 degrees although before I found out that I had the keel only half way down I nearly capsized it a few times.

Have fun and enjoy your new boat

Re: Siren 17

Hi everyone! My apologies in resurrecting this old post, but I am also new to sailing and purchased a Siren 17 in unfortunate condition. Most pieces were broken / missing, including portals, main hardware that attaches the boom to the mast, and the rudder. A friend of ours had a Siren that was destroyed in hurricane Sandy, and we benefited through his donation of a rudder and some hardware. After purchasing a Nautos swivel block to attach the boom to the deck, and buying a new fixed gooseneck from Dwyer, we are almost ready to sail! My question is that we have the halyard currently attached to the boom, holding it horizontally against the mast. Obviously this needs to be attached to the head to raise the mainsheet, but does there also need to be another line to hold up the clew end up the boom, or will the mainsheet be enough to support it? I've been looking at pictures in books and online, and some appear to have a secondary line going to the end of the boom, but others don't have one at all. Thank you in advance for your help!

Re: Siren 17

I know this is an old thread, but I suspect there are still some folks out there (like me) who have recently become a Siren owner and are trying to figure things out. Luckily, mine came with some old paperwork that provided some answers. I have attached a diagram showing three different rigging arrangements for the main sheet. When I bought the boat, it had the "single block" arrangement, which didn't seem very efficient. I figured the other options were progressive improvements, so I used the specs for the "boom-end" arrangement to re-rig the main sheet, and it works pretty well. The "secondary line" you refer to is called a topping lift. It supports the end of the boom, but should be detached and secured when the mainsail has been raised. On the Siren, it consists of a 3/16" by 27 foot line.
