Hello Sjoormen,
You are making a very good job of constructing the hull of your boat.
I think you should spend some time thinking about all those rigging lines and radio gear, which will be covered up by the deck.
When the deck is fitted into place, will you be able to repair any of those lines if they were to snap, or come off the pulleys ???.
Worth thinking about now, while you still have the chance to imagine any future disasters and how they could be fixed !.
The keel could be made at a lighter weight and still be effective, by making the keel deeper.
A "true to Scale" yacht will always be blown about in the wind, the J Class yachts in America, have a keel which is 50 mm deeper than Scale.
They still heel over a lot in the wind.
You can scale all parts of your boat, but, you cannot scale the Wind !!.
The keel is not seen while the boat is sailing, a deeper one will make your boat sail more like the real one did.
Have a look at the keel fitted to my Schooner, Bluenose, she sails very well, the real boat did not have a keel.
People will understand that a keel is required on a model like yours, with all those sails.
John.
