Den er konstrueret som den gamle blot lidt længere langskibs.
På den gamle mastefod var det midterste firkantede rum fyldt ud med glasfiberspartel.
Regner med at gøre det samme blot med epoxy, så er der da ikke noget der kan give efter og synke under mastefoden.
Her billeder af det finér på kant der skal støbes fast.
Regner med at give det 6-8 lag 200-300g rowing og epoxy så burde det kunne holde - samtidig med den massive klods i midten.
Have you checked if there are cracks in the current mast foot? In my boat, there were cracks that had grown in the welds for the 'ears' that attached to the stays that were inside the boat.
SvarSletIf you look closely at the design, the original mast foot is really isn't able to provide very good support except for fore and aft. With a little creativity, you can build a much stronger and lighter fiberglass construction that will weigh less and provide better function. The aluminum piece can then be screwed/glued directly to the fiberglass without the heavy stainless steel clump.

Hi Greg,
SletThanks for the good advise.
My plan is to start by laminating a couple of layers rowing with epoxy all over the bottom of the boat.
Then afterwards I will mount the mast foot stringers.
And give them 4-6 alyers 300G rowing.

Another thing to keep in mind is that if any water leaks through your mast, which usually seems to happen, it will land in all of the spaces around the mast foot... this is a real pain to keep dry. This year I am filling the gaps with pink foam and then fiberglassing roving over them to make the whole surface into one space. Hopefully this will make the leakage easier to deal with :)
SletI am also going to try and get the mast watertight again, maybe it will work on the third attempt!

Hi Greg,
SletGreat idea to foam up and glass the mast foot area dry and with a flat area.
Only thing is that i would really like to be able to visually inspect what is going on around the mast foot - at least the first season. Remember the sail area has been increased a lot and the pressure on mast and mast foot is increased substantially. So the first season i'll have the whole area visible.
But next year I would like to foam it all up and put a couple of layers rowing on top with epoxy.
