40 Crack on keel to hull

My boat is currently in italy and I am attempting to bring her in december to Portugal, where I will haul out and do a big work on the hull and paint water line. But there is a crack (20 cm) between keel and hull (normal I have been told) as keel bolts are ok and bilge is dry.

Just for the 1000 miles passage I am thinking in applying Sika flex 291i or 292i. Just to protect from water geting in the epoxy. 

Any thoughts? Any other advice?

Yes, these are relatively normal..  The separation you have I have seen before.  When I get this on Stormsvale, I open it up, rough up the lead and hull with 40 grit and fair it with expoy filler.  I remove any loose filler etc before fairing. If you dont it will require another fix relatively soon.  I think I did it last time about 5 years ago.. Lars may have better advice. I suppose a flexible sealant may be better but it is key to get all the loose fairing away. 


Have a nice trip... we are in winter prep mode here..

Dear Duarte
The recommendation is to also tension the forward keel bolts. 
According to old information their size is M20. pls check. I can then give recommended torques. The forwardmost bolt may have a bottom end washer recessed into the leading edge

Thank you Lars as always.  

I will try to do that once I address the mast step. Although bolts a very well covered in some kind of rubber and will be a pity to unprotected them.  

I just want to put some kind of isolation in the keel to do the 1000 miles passage to portugal.  Once here I will address properly as you say and with epoxy.  

many thanks for your time.

Hi Mike. 

thank you for your reply.  
I'll do exactly that once I have the boat in Portugal.
