Home >> How do I? >> Overly thick Daggerboard
Here is a key dimensions I used when a 2nd Dagger Board ordered from RS Parts store wouldn't enter the slot beyond the lower  foot taper:-

Down the uniform chord, i.e. straight, part of the board the board is, or should be, of uniform thickness between 8 cm < - > 16 cm from the leading edge.

This thickness can be measured sufficiently accurately with a pair of outside callipers.  It should be 29 mm.

And should be the same at: the top of the board foot, midway down the parallel part, and at the top of the board.

My 2nd board measured 31 mm.  I considered sanding, but couldn't guaruntee I wouldn't be altering the profile; rule infringment.

When I contacted RS with the measurement and order # a new dagger board was sent immediately.

This after doing other checks on the leading and trailing edges for uniformity, and straightness.

I hope this helps.

I used Harken McLube Sailkote. I use it on the mast track and sails, so I tried the foil and while it was a little bit easier to pull up, it didn't solve the problem. It also made grabbing the centerboard a problem in a capsize because it was so slippery. Won't do that again. 
I also washed and cleaned the whiskers in the centerboard box really well - I figured sand and dirt was making the fit too tight. But not real change there. It makes landing on the beach really tricky and I wish it had a daggerboard.
The gelcoat is pretty thick on the hull, but the foils are not all pulled from the same mold, so I don't know if the gelcoat is the same thickness. I'm going to thin mine a bit this winter when I repair the chips and maybe replace the whiskers while I'm at it.

Hi Lorrian! My daggerboard is also starting to show some resistance against being raised and lowered, and I'm curious about your silicone fix. Did you use silicone paste or spray?

Thanks for all the advice.
Despite sanding board down yesterday, just as bad today.
Shall try washing with soapy water and shaving next week, before Warsash.

I found that my fur had partially come unstuck and folded double. This caused stiff action when raising and lowering. Trimming the fur back sorted it. No problem since then.

Have you tried shaving (literally) the fur?

Thanks Tom.
I shall certainly give the carpet a good wash.
It has been an issue from day one of receipt of the refurb'ed boat from RS. And I believe from various sources that there was a batch or more of overly think dagger boards.No replacement forthcoming despite request.
There is a noticeable increase in profile thickness at the heel of the board, which is where it appears to stick.
Anyway, I've done some sanding, and cutting to get back to smooth and hopefully this will help.

I had the same problem until a few weeks ago when I followed advice from this site and others....I gave it a thorough cleaning and a polish. I also gave the the bit of fur at the bottom of the casing a good wash with clean water to remove years of salt build-up. The improvement is amazing and now I lift it (one-handed of course) to check for weed whereas before I only lifted it when I knew I was slowing down. And,as you have experienced, coming ashore is far more elegant.

Getting really tired of the battle I have with my daggerboard every time I go sailing.
The shark's teeth edge being a testament to our launching area and not being able to move the thing without standing up and pulling with all my strength.
I'm about to sand down the thickest parts. Any advice from anyone. i.e. how far can I go before damaging the gel coat?
