Dinghy sling.

Ian

Greetings. Having purchased a preloved 9’ RIB recently to zip to local spots without taking the big boat and to commute to share when anchored, I am looking at options without a full on davit system. Why - because I would have to pull up the stick down MarineMat on the swim platform and have remade to suit, I have no davit points on it and I haven’t seen anything suitable to mount on the edge of the platform vs the top.

The Admiral found this which looks like a good idea and wondering if anyone has used or seen them and has some feedback.

I assume with a 9’ dinghy your plan is to leave the motor installed when transporting?

I am very happy with my solution but it took a bit of rigging.

Thanks @YYZRC, I like what you have done and am open to either engine on or off although your method lends itself to leaving the engine on. Only problem I see for me is I don’t have an enclosed platform like you do, mine is open so I don’t have the box to bolt through to.

YYZRC

I wish my platform wasn’t open for this reason. I would have cut square holes in the edge and ground the aluminum flush with the edge of the platform and the bolted through the platform. I did this on my old boat and covered the screw heads with the seadek.

Yeah I agree that would be better although couldn’t you cut square ones in the end and push through and secure from the bottom? However I’d still not avoid the same problem - have to fix/do something with the MarineMat.

If I did that, I would have water flowing into the bilge through the receiver and I wouldn't be able to pin the extension in the receiver.

For $300 it's worth a shot, but it looks cumbersome to retrieve the dinghy.  Any other dinghy solution is $1000+

Ahh, I was thinking this was a closed box.

The company is outside Boston so my next visit that way - may be closer to the Cape - I can call by and have a look. Worth a look for the price.

If your RIB uses a 4-stroke outboard, you can only lay it one one side or oil will fill the cylinder(s) and presto damage. 😬. My 9.9 2-stroke weighs in at 65# and trying to remove/install while in the water is just not doable. The newer 9.9/15 hp come in near 100#. You can get a rotating engine mount from Weaver davits to solve the 4-stroke issue. 

It can be REALLY difficult to pull up a RIB on edge. Just personal experience. That was just a 95# RIB less engine. I went with the Hurley H3o.  You could just cut the marine mat to fit in the davit.  No need to take a big piece out. I tried the ‘save money’ route for a davit system and wasted probably $1k in the process. 🙄

The Weaver rotating mount solves the oil seepage issue for 4 strokes but I'd like to meet the person who can pull up a 95 pound motor plus a 100+ pound dinghy to 90 degrees!!

@Black_Diamond my 8HP is around 70lb and I have taken it off and on a few times from the dock and another guy’s 9.9, it’s not that bad. Also aware it can only lay on one side (port in this case) but I also wouldn’t want it hanging on the RIB anyway if I rotated it up vertical. I’m reluctant to cut into the MarineMat as it has that made to fit and finished look.

I’ll look at the Hurley though.
