    Concept boat design is the design work done for the purpose of providing the desired purposes on the boat. Excursion 36 has a comfortable seating area, sun pad area, icebox, toilet and much storage areas. The Boat can use V- Drive System, Waterjet system or Sterndrive system. Excursion 36 has 13 person capacity. This is a multifunctional workhorse used for touring, exploring, diving, ferrying people or party. Excellent sea-handling and performance, together with its functional, yet comfortable lay-out lies at the basis of the Excursion 36 undisputed reputation.

    Can I be the devil's advocate, I like the shape but is it multi-function? No serious fishing, diving - how (swim platform), ferrying people around with limited seating seems a bit dangerous, I think it needs more thought.

    Impossible to comment on how this design achieves the objectives that the designer had proposed. The appearance is nice. Many sharp edges, which can be a danger to passengers.
    Yes, a nice render.

    Well for fishing I like the cockpit to be clear, it's a working space. For diving, its needed a method to raise tanks and equipment, it's a huge sandbar boat to me.

    Hi Jorge, best scroll down the by the OP in post #1 provided link for more renders of various interior and stern layouts, for different applications of the boat, you have to choose the one that suits the application of interest most, and then judge for applicability of the design.

    I think the accommodations lacks practical boat use experience, though the rendering is lovely. How much at sea time did the designer have, before drawing this puppy up? Have they every dived off a 35' boat, with no platform? How about fished or towed a set of skiers? It seems really easy currently, to "design" wonderful pictures and possibly full CAD derived plans, but has the designer any clue about what the boat might actually need when out there, preferably from personal experience? That to me, is the world's biggest bow rider and looks to be as dangerous as you can get, for a craft capable of venturing into waters as deep as that can.

    Not trying to be insulting, but tell me Umut, how much time have you spent on a pleasure boat? Just get close, it doesn't have to be down to the hour or even the week. For example, I was born on a boat, 150 miles off the coast of Virginia, heading for the bay, when my mother had me and my sister on an old schooner, the boat being delivered for a family friend. I was raised on an island in the Chesapeake Bay and grew up on and around boats, throughout my childhood. I can't possibly count the thousands of hours I've spent on pleasure and working boats over the years, mostly because of my age now, but I've seen some sea miles, with several ocean crossing under my belt as well.

    How about you Umut? Now, I'll admit I have a more than usual level of experience than many, but I'm not unusual in the industry. Have you ever lived aboard for extended periods (months, if not years, not days or a few weeks). How long have you ever been at sea solo? Have you ever crossed an ocean in a relatively small boat? No single designer or NA, that I've met, hasn't crossed an ocean, making them uniquely in tune, with some of the things you just can't envision, unless you have.

    My point is, the skills to draw up pretty pictures and even develop the engineering skills, to actually design something, that will satisfy class requirements is one thing. It's entirely another, to have a clue about what is necessary or convenient or desirable, if you don't have the "sea legs" time under your belt, which is the whole reason I innocuously ask about your experence.

    Hi

    Hi, Jorgepease I didn't say fishing. I said diving like the photo. This diving work is fast and more times during the day.

    Hi Sir (PAR Design),

    First of all, I respect what you say.

    I'm Naval Architecture and Marine Engineer. I'm working small boat (from 3m-15m) design and manufacturing during the last 10 years. I do not have as much experience as you. Only sea trials and several times stay on the boat.

    You can check my website: Best Boat Design - Boat Design and Boat Plans Site | Boat design, Yacht design, Boat Plans https://www.bestboatdesign.com

    I agree with your comments. Also, I work to improve myself.

    Regards,

    Yes, sorry I did check out the link after and see your other configurations.

    For diving, should be a benches with tank racks just behind, that skimpy dive ladder to a swim platform way out of the water is hardly purpose built.

    13 people trying to get tanks on and in the water fast as possible equals big dangerous mess.

    I don't have experience designing boats but I do have 28 years experience as a commercial and recreational diver, all out of boats <10m in length.

    Key considerations are: -
    - Space to gear up (a diver need about a 1.5m x 1.5m square of space to gear up); and
    - An easy way of getting divers and their equipment into and out of the water - diving equipment is heavy and climbing up or down while wearing it is difficult.

    I suggest: -
    - Delete as much as possible of that large raised deck you have at the rear of the design - it will be an impediment for divers.
    - Cut the engine box down to the minimum space it needs to occupy.
    - Re-design the stern with a boarding platform that will be very close to water level when the vessel is at rest. The walk through door in the transom door of the side console configuration is good feature. It would be better if you removed the steps and added a closeable panel.
    - Attach fold-down or pocket-stow boarding ladders to the aft edges of the boarding platform, ear the corners. For diving a "T" style ladder with a single stringer running down the center of the rungs is preferable/easier.
    - Consider railing around the boarding platform with gates that open to admit divers (if aesthetically acceptable). On some boats I have seen the fold down ladder also serve as the gate.
    - Plenty of hand holds in the gearing up area and at the boarding platform

    You also need to think about: -
    - Storage of dive bags, weight belts and tanks
    - Plenty of drainage
    - Spear gun racks?
    - Kill-tanks?
    - Freshwater shower?
    - Private areas for anyone who may require them to get changed?
    - An on board compressor for filling bottles?

    The weight distribution needs to be thought about carefully. Dive gear is heavy and storage location affects vessel trim and stability significantly. This depends to a large extent on how many divers will be on board and how cold the water is. Colder water requires thicker wetsuits and heavier weight belts.
