Evening all,

Headed out on my maiden voyage in my new 7 at the weekend. Had a few issues extracting the daggerboard whilst hurtling towards the shoreline which wasn’t the greatest.

I had a reasonable amount of rig tension on and quite a bit of the slot gasket fluff has fallen off but has anyone else had a very stuck daggerboard and if so are there any general tips on how to resolve this? 

Cheers,

Simon

Hi Simon,
Welcome to the fleet.  Not a common issue I've heard of  but with the raking boards it's worth making sure you're pulling it up straight to avoid getting wedged in at an angle either forwards or back. 
 
Could be that there was new slot fluff put on that hasn't been used yet?
 
Rig tension really shouldn't be impacting it but worth checking out the forums on how much to put on.  Normal range is in the region of 32 on a loos guage.   I'm sure others will have more detail to share.
 
By the way, there's an event at Queen Mary on 2/3rd November which might be a good place to see some other boats and pick up some tips.  Normally a good mix of standards at events and very friendly for help for those new to fleet.

Simon, Unfortunately, it is something that used to plague my boats.   It won't help you but the daggerboard box has been redesigned to prevent this from happening. 
The first point that you have now learned is to always check that the board is loose before coming ashore.   As Matt has said it needs to be straight (not raked) and forward in the box before you start pulling it up, so the first action is just to make a gentle pull to check it's OK or to ease it forward and straight before you pull it up.

I would always have to ease the rear end of the bottom of the box (and sometimes all of the box) with sandpaper and then line with 50mm wide velcro ( so that it stuck to the edge of the slot and the inside of the box).  So long as the board is bearing on the velcro it will be easier to raise.

If you have the time sand and reline so none of the daggerboard gets to rubs directly on the Gelcoat on the inside the box just to avoid the inevitable scratches on the board.

Also, head over to the 700 facebook page. This forum is not very active anymore.

Thanks both - some good tips!

I will use the Facebook page from now on.

I have a relatively new boat so the box should be the new version. I have bought some daggerboard fluff and will do some work to sort the slot out and remove all friction.

The boat is set up with the correct rig tension and rake 450-500 lbs and 7300 rake so all within guidelines.

Cheers gents,

Simon

HI Simon,
I think you bought the boat from Lee?  If so, you've got the older style case with the raking board.  
New cases were only introduced around 2 years ago and use a slightly different daggerboard (the aero one).
 
 Don't worry about that though, you'll find it fine when you get used to giving it a wiggle to make it lift straight up.

Cheers matt, yep I have just bought 1013 from Lee. 

At present a little more than a wiggle is required but I’ll sort
it. The boat is set correctly which is good, dagger board slot needs some fettling.
