    I got to thinking (I know, I Know) about putting the dink up on the Weaver davits with the motor still attached. But, the more I looked, the less I liked the idea. I looked at other davits, and there was just something missing with them, although I liked some of their concepts. So.....I made my own, which combines the Weaver receivers with other "types" of davits.....customized to satifsy my personal needs.....And part of the beauty is that I can still slip in the Weaver Snap Davit if the going gets rough and I have to flip it up.

    So...I now have a new davit....I guess I should name it.....HMMMMMM.....Dom's Dinghy Davit....yup...that'll work..... :grin:

    I made some drawings and went to a local marine fabricator....he made the mounts to my specs.....Your critique is welcomed....

    What'd you shell out for it?

    I've been thinking along the same lines. I like the removable 'shoe' aspect of the weaver. But dislike the gouging the flip-down davits charge.

    I'd wonder about repositioning the shoe so that it didn't slide fore/aft but port/starboard and perhaps facing each other. This to avoid motion of the dinghy from shearing a pin and dislodging the shoe.

    I never turn down the opportunity to criticize someone else's work.

    Actually, that's nice work. I would question, however, the use of bungees as the tie down. I'll try and send you a picture of the factory tie down on my hydraulic platform and I think you would need to do something like that... It'll be later in the week as my boat's bottom is getting sanded and painted today through Wed.

    I don’t mind when someone runs with an idea to use it for themselves, but when they take someone else's idea and start to sell it, it becomes piracy. I take piracy very seriouly as most entrepreneurs do!

    Dom,
    Seems to me that once you buy something you can do whatever you want with it (with in reason). Who the hell is Boater for Life and whats his problem? Maybe we need to keep vendors off the board. :smt013 Thats like saying I can't change the wheels on my Corvette (well not really but you get my point........ !!!! )

    Hmmm, how to unsuccessfully market a product... continuously jack up the prices, play games on auction sites and then antagonize people on web forums. Not quite what most would call a recipe for success...

    Care to actually point to a reference to this so-called pending application? They are public and can be searched, you know...

    Make sure they're stainless. No sense having them rust and end up dripping on the swim platform. Are they removable from the transom of the dinghy?

    Excuse me while I step up on my soap box.......

    Generally speaking, I think it's a good thing when vendor's visit and contribute to the CSR site.

    However, when a vendor makes the assumption that a CSR member who modifies or customizes "anything" to be used on their own Sea Ray will then be going into business to sell and compete with that vendor, and then try's to publically lecture to that CSR member, I quickly change my opinion.

    This forum is not, and should not, become a venue for vendors to make subliminal legal threats against CSR members who enjoy working on their boats and then sharing their experiences with other CSR members.

    If a Vendor feels that there has been an infringement on their patent, then that Vendor should seek their own relief OUTSIDE of this great site.

    The last thing we need here on CSR is a slew of Vendors, or worse, lawyers, breaking in to "tell" all CSR members that any post in the "Modifications and Customizations Forums" are not allowed because "they" say so.

    I don't want or need anyone's blessing or permission to modify "ANYTHING" that I "do to" or "use on" on MY boat.

    I'll step down now......


    So.......... Frank, what do you think of "Dom's Dinghy Davit".... :grin:

    Actually, the tie downs are plastic.....all the parts on "Dom's Dinghy Davit" are either Composite/Plastic, rope or 316L Stainless......I believe that the Weaver Receiver is also 316L Stainless......

    I must not be seeing something in the pics - what keeps the lever insert from sliding out of the snap davits? Is there a pin or something?

    Looks good. :thumbsup:

    Mike:

    Yes..... I used the Retainer Pin that comes with the Weaver receivers. If you look at the first picture, you can see the hole in the back of the bracket's base where the pin inserts.

    Thanks.....

    Ah ha. I though that might be it, but I wasn't really sure.

    Nice work.

    Doms Tip Up Davit

    This innovative agglomeration of material and concepts is supurbly executed and causes one to think more of St Croix than Hurly, but heck thats just me.

    I'm an owner of the Hurly Davit system and have become very familiar with what it will and won't do. I know one thing, that Miss Michigan wouldn't get my 310 Rib on my Hurly Davit System that is for sure.

    I love the tip up concepts because they are a low cost answer to a need in a high cost world of davit systems.

    I've a 460 with a swim platform that at the surface is nearly 24 inches off the water. The Hurly fixed pivots add about an inch in height. My Avon 310 RIB is 46" wide, which means the center line of the dingy is about two inches short of mid point on the bunk when the dingy is 100% verticle and the davit is verticle (getting a inflatable floating on one tube verticle is a real trick, doable but a trick and is very amusing to the sea lawyers on the dock). Which means the fulcum to the lever is not to the advantage of the skipper, no indeed that outboard tube, fiberglass hull and 50% of the mighty 15HP elect start Nissan will fight back in this circumstance!

    My Rover weighs in 140#, 15 HP Nissan 140#, Fuel, oars and gear and you have a 300-315# rig which you must get vertical or it will slide away from the bunk, can do no problem just lasso the out board tube .... then lever the rib back and up into the bunk ... not so easy ... in fact two strong hefty guys just make it happen but then we weren't wearing bikini's sooooo.

    The Hurly System and other tip ups seem to me to need an application that involves a swim platform that is closer to the water than 1/2 the beam of the dingy, the less the better. If the platform is higher scrap the tip up idea and go to plan "c". But for a 25", all in high platform and a 46" beam dink weighing in at 300# plus, the tip off is a back breaker and boarding this in anything other than dead flat seas is simply silly to think about.

    All that said, the bunks provide a reasonably good place to strap down a dingy on a narrow swim platform. I traveled througout the Abacos and in some very challenging Atlantic open seas with my rover in my Hurly Davit System and it rode there fine. On the other hand I never took it off because I knew I couldn't get it back on myself and I'm reasonably fit strong 300# gorillia. The Admiral simply refused to be a party to such a comedy .... on final examination I can't blame her ...


    Hurly Davit System and other tip ups ... great ideas, really neat just not for this skipper. Next stop a power lift ....
