    Hello Boat Designers, I'm looking for suggestions for a sailboat design that is around 30ft. long, has a flat deck, and a large spacious cabin. This sailboat does not have to be fast. Any suggestions or links will be appreciated. Thank you.

    Do you mean a raised deck?

    Sounds like a flush deck. It's doubtful that you'd get standing headroom in a 30 footer with a flush deck unless the boat is quite burdonsome (maybe 15-18,000 lbs displacement).
    What I mean to say is, of course you could do it with a relatively light boat, but it would be rather high-sided and probably a little clumsy looking. It would sail on its mooring and the hull would catch a fair bit of wind going to weather.
    Look at the Stone Horse design. At 24 ft, and moderate displacement, the cabin is a real cave, having very little headroom, being perhaps 1 1/2 feet shy of standing headroom. At 30 ft, the same design upscaled might have 5 1/2 feet of headroom.
    You can get headroom and sleekness at 35 ft. I would suggest a small doghouse if the boat is 30 ft, enough for the head, galley, and a bit of the berth area to be full standing headroom of maybe 6 ft 2-3 inches.
    It needn't be wider than 5 ft or longer than 8 ft, so you still would have a lot of deck. Most importantly, you'd have low windage and a more attractive boat.

    Was meinst Du? Deck ohne Aufbau, oder sogenanntes "Backdeck"?

    Flushdeck sailboat

    Boatdesigners, Thanks for the quick responses. My background is architecture and set building and this is why i may ask some silly questions and use the wrong terms. Sorry about this. I do mean flushdeck sailboat. I looked at the
    Stone Horse design and this is a great suggestion and i'm still looking at the Bolger 29.

    Is it possible to have a flushdeck sailboat at 30ft with 6ft.4 inch headroom and have a deeper draft so the hull won't catch so much wind and look clumsy? As mentioned by Alan White.

    I assume the draft of a sailboat is determined by weight (?) and is it a crazy idea to add extra weight to the keel in order to have a deeper draft?

    Herr Richard: es tut mir Leid! Ich sprachen kein deutch! aber, ya, eine segelboot mit kein aufbau. Danke.

    Peter Cole designed some high decked boats in the 1980s. The Nantucket Island 33 was flush deck:

    They look better in the flesh than the photos here.

    There is also a Cole 31 that I think was built with a flush deck but the most common variation is the Eastcoast 31 and it has a slightly raised deck that is not quite flush. The ports are in the side of the hull though similar to the NI33.

    Second hand boats are still available around Australia for a reasonable price. They are large volume boats for the length and sail well. The 31 was designed to IOR half ton rule and was very competitive. Not as extreme as some - really nice on the eye. They were too pricey for me at the time but were my first choice.

    A sailboat is a collection of comprimises. You can't have it all but neither can anyone else. You needn't go too heavy, too deep, too clumsy looking, or too anything. You have to comprimise and give a little in a lot of areas.
    I think there are plenty of boats out there with flush decks that you might find attractive and functional.
    Earlier, I was talking about ideals, but you aren't so far off the mark in your requirements that nothing can be done. You just need to find the right comprimise, that's all.
    Is this a deep sea boat or a coasting boat or what? You start with the intended use and go from there.

    Good idea to start with the intended use and go from there. This boat would be used in not so deep and shallow lake region in Germany, outside Berlin. My main purpose is to be able to sleep comfortably for a night or two and be able to sail very short distances. The sailboat can not be too big because i only have so much room in my backyard! 30ft is max. Thanks.

    Hmm, that makes the task not easier.
    You have choosen to sail the shallowest region in the European waterways. (naturally)
    Neither the lakes and rivers in Brandenburg, nor the Müritz Nationalpark allow for a draught that would make your idea possible.

    Due to the lack of strong winds you should give up the idea of a flush deck I recommend.

    Regards
    Richard

    Hi Richard. Thanks for speaking english. Yes, i live in Potsdam. The lakes here are not deep. What would you say is the deepest draught a sailboat can have in this region? 1.25 meters or 1m ? Thanks.

    Deepest possible should be around 1,5m, deepest sensible 1m, even that´s a lot, because there are quite many shallow regions. The Oder is sometimes below 1m during summer (just as a example).

    seems to me that a center raised portion that would let you move about to where you want to go would suffice

    do you need full standing room over settees bunks/beds galley counters etc?

    what is your reason for wanting full flat deck area?

    after all said you might want to consider a catamaran
    this one from the top of a quik search is 36ft and has little draft, planty flat deck and spacious cabin, 30ft cats there too
