I would like to carry my Oasis on the back of my boat, would like to use a manual Davit (dinghy hoist). Mointing the Davit is not an issue, but how or where to attach the cables or straps to the Oasis is? I keep my boat (and the Oasis) in the Oceanside marine, Pacific Ocean is usually not warm. :o

Could I attach cables to the handles on the side of the Osis? If this would be ok, I’d still need to figure how to stop it from rotating/tilting forward or back?

Another alternative would two Davits with a strap on each which would fit under the hull. Conceptually this works, but would be problematic getting the straps under the hull while sitting in it.

Any ideas appreciated.

Points of attachment are problematic. Plastic will "cold flow" over time and possibly pull out of the hull. That is the reason we warn against hoisting from the handles. If upright wide webbing straps / slings may be best.

As the best way to store the kayak is upside down on the rails... holding it on davits would also be best upside down. I made a hoist in my garage for mine that works pretty slick.

I am really happy with my setup.

I (like most of us) have two primary issues related to kayak storage. One... limited space. Two... ease of the storage and use of the kayak.

I have made a kayak hoist before and was happy with the use, but it did require carrying the kayak into my garage, setting on saw horses and only with the garage door shut, could I hoist. It was a bit time consuming, but clean out-of-the-way storage.

I moved to a new place, so I re-configured my hoist system and it's simply AWESOME!! (I think :) )

I can drive into the new garage with the boat on the roof, so I wanted to be able to hoist right onto and off the roof rack. My boat length, garage and vehicle height are ideal, so may not work for all. But the concept would work for many applications.

This hoist keeps the boat inverted and places the carrying loads on the cockpit side rails just as though on the truck roof rack. This is ideal.

The Hoist: Two overhead pulleys are attached to heavy duty lag hooks threaded into joists. It's a double line system that has two 3:1 purchase blocks below. It has lines passed through scuppers and a pair of dowel cross members (these could be stronger or be of another material), but this works for my Maui. The hoist lines feed to the wall and then down to a pair of cam cleats. I also tie this off for security.

(Drawing / details at the bottom of the post)

I pull the line through the scuppers (The tail of line hanging down allows me to easily pass the line down through the scuppers and then pull the loops through) and then pass the cross members through the loops. I have also added two "humps" of tape to mark and keep the dowel centered. No knots to tie... just two cross members passed through the loops.

Image
I then simply hoist the kayak up off the roof rack. The load is balanced and stable.
The dowels are what I had on hand and could be stronger, but they worked for proof of concept.

The double line system is easier to rig and allows you to pull the lines down when setting up to hoist and adjust height independent of the opposite end while hoisting. I had these triple blocks, but note that doubles there is all that is needed.

Boats without single / centered scuppers aft might have to use a beam setup to split the line to both (cart) scuppers.

Thx Matt. My issue of course, is trying to lift it from the water directly onto my boat. Unfortunately it’s much too heavy for me to do alone, or with my wife (I’m 70). Hmmm.

If you used some attachments and then supported it properly when raised... that could work.

Thinking of getting an i11 instead, need to do a bit more research on them. Will take one on a Demo, either in Oside or DAna Pt. I may post a different thread later.
