We have a Fairline Squadron 56 & have recently acquired a 4.8mtr rib with a 60Hp Mercury Mariner 2 stroke which we would like to take with us on our future travels, but we have two problems..
1) The hinged davits on the boat are designed for 80Kg each
2) The swim platform is no very deep & even Hurley type davits wouldn't take it

The boat has a passerelle & I'm wondering if there is some way the hydraulics of that could be put to use?

You really need to buy a bigger boat to carry the bigger tender��

Speak to ABS in Plymouth about it as they have a couple of moulds for various platforms that are attached to the stern of boats to carry similar RIBs. That would use the hydraulics.

Otherwise tow it or road trailer it round, we used to tow a Boston Whaler around but we were displacement and 120ft.

RIB is 208 kg. Not unless he has several Weetabix for brekkies.

Most hydraulic passarelles wouldnt be rated at that sort of weight. The rams could be made to lift that weight possibly but dont expect the mountings etc to be able to cope.

The pictures of the Squadron are different to mine. Mine has the smaller bathing platform, which is also an issue. Towing isn't really an option surely? & road trailer definitely isn't..

My thinking was adapting the hydraulics of the passarelle to lift it & then having some sort of extension rail to the platform for it to rest on & remain tethered to the lift.

if you do a websearch for <<RIB "swim platform"<< (or "bathing platform" :) ) you will come across pics which show RIBs on small platforms, but swung round so that the beam is vertical. Even pictures of fittings to enable you to do it.

If the boat is a 'keeper' then how about fitting a hi-lo platform from H+B Technics? Tender launch, recovery and storage issues all solved.

Anything is possible but you are pushing it here. A 4.8m rib with the engine raised will stick out significantly both sides of sq56, so mooring will be a problem whether side to or stern to. It really won't look good

Squadron 58 typically had Avon 320 jet rib or 3.4 m outboard ribs, and I knew one fitted with the Avon se420dl tender and 50hp Honda outboard (= lightest 50hp 4T available), but that was right on the limit size and weight. Pictures below shows a Novurania 430 w Yam 78 on a squadron 78, and this is close to the limit (there is no slack on port side, and a 0.5m space was left stbd side for letterbox passerelle to come out). You are talking about a bigger tender (4.8m vs 4.3m) and a smaller mothership, sheesh!
You can probably do it if you're happy with sticking out boat and the engineering needed to make a platform for the thing, plus the looks, but really you'd be better trading it for something a bit smaller I think (like 3.85m max)
