    I want to design a small (less than 30 feet) but still capable of long-distance sailing voyages across the ocean.

    Outdoor activities in the ocean voyage is dangerous, and therefore reduced the space on the deck and expand the cabin space.
    She has a hard top cockpit, driving in the cabin rather than in outside, in the most severe sea conditions may be normal navigation.

    External structure suitable for cold weather to maintain consistency.
    Gap at the bottom and the cabin filled with foam to ensure the insulation resistance and sinking.

    That looks like a slow boat that will have an uncomfortable motion at sea. Have you been sailing much? Try sailing different kinds of boats, preferably in high enough winds, to get an idea of what you may like.

    If you really want the interior to be roomy, as you say, make the cabin longer. That will also provide something to hang onto if you do have to go forward in bad conditions.

    Those are very large windows. It would be nice if they could be made strong enough, but if it were me, I'd cut them in half vertically and bulkhead off the pilothouse from the rest of the interior. Otherwise, you've GOT deck space galore with that flush deck, which I do like.
    Another five feet of length would probably preclude comments about excessive windage. That is, if you expect to have standing headroom.

    Little boats on the big ocean is a bit like pull'in too many Gs in a late model fighter plane. It's hard to find anyone willing to take such a beating.

    Easy Rider.

    Well windward ability isn't going to be this boat's strong suit, so don't go crazy on the bulb and appendages. With that deck house you'll constantly weather cocking and marching around your anchor rode or mooring. Hard to tell whats going on with the hull shape, but sailing preformance doesn't seem to be one of your primary goals. Considering the cost of stock plans, where the serious hydrodynamic issues are attended, you might be best advised to make accommodation revisions to them, rather then attempt to design from scratch. If you have to ask why I recommend this, then the more the reason you should work from a set of stock or custom plans. Is this the latest version of your radius chine, steel, ocean cruiser?

    Donna Lange did a solo circumnavigation in a ~30ft Southern Cross. Rather than reinvent the wheel you may consider one of those or mirror the primary boat specification very closely.

    I would prefer a 35ft to 45ft boat myself. Provided you are a good sailor, are keen on avoiding weather systems and use a well designed boat I don't see any problems. Donna did a great job with all of the above including rounding Cape Horn at just the right time.

    It's all in the timing.

    I would hate to cruise in the tropics in a boat that forces you to stay inside most of the time.

    I would hate to sit in the sun all day long.

    Better to open the rear door and the front window, isn´t it?

    On a 29' boat the pool is out board, so a big thing to cover...
