Can anybody tell me if Sikoflex is a real superior alternative to traditional caulking below the water line, and if so which Sikoflex product would you recommend?
If you go to the Sika Group site (Google should find it easy enough)and choose 'Marine' you will find detailed info' about all the products and how to apply and care for them. IMHO I would say yes they are excellent products but have to be used as per manufacturers instructions with the correct preparation and primers.

Couple of years ago , I renovated a 50 year old mahogany carvel built
yacht where many of the seams had opened up. Used Sikaflex 291 with
the appropriate primer and had exellent results -no leakage whatsover
even after the boat planking had swelled to normal.
Polyurathen is a good product as is polysulfide sika at least make a product ment for marine use though many boat chandlers sell the less expensive houshold product having less UV protection, I would and do use 2 component polysulfide for the deck,but under water never
A cavel hull should take up if it dosent then you should recalk with cotton, for small leaks or whatever i use putty with a bit more linseed oil ive used this where ive had wood softened by the action of hull fittings and on on the planking along the waterline in small areas ive bein able to dive with the putty and fill the damage around the fitting later when i find a yard that will let me stay out longer than 3days i remove the fitting cut the wood away and make a graving piece if i had used sika i wouldent have got the fitting out and the job of cutting away the wood would be harder
