    Default Boarding Ladder

    First post here for a while.

    The latest project is a folding teak boarding ladder adapted from the excellent plans in Sam manning's article in WB issue 84. The changes are mainly to add an additional 2 steps due to the freeboard of the boat involved (Paine 34).

    The teak is recycled from a bookcase liberated from a local Lifeline store.

    The first 2 photos here show a mock up of the design in pine and a test for the rung to sides attachment. I wanted to avoid screws into the mortised end grain of the rungs and will most likely use the technique shown . This involved a through tenon with 2 wedges glued in . The 2nd photo shows a test joint that has been made with pine and coachwood wedges (differing colour for clarity); the joint was then sawn in half to check what was going on inside the glued joint.

    The first question to post here is on the type of non skid treatment to use on the ladder rungs. The rungs are 70mm width ( 2 3/4") and the ladder will be finished with Cetol Marine oil. At the moment the 2 leading candidates are to install a pair of glued splines on each rung. These would protrude no more than 3mm (1/8") but provide a non-slip feature. The 2nd option is to plane 2 grooves in each rung along a smiliar layout plan to the splines. I would be grateful for comments/photos of what others have done.




    Cheers

    Hi Peter,

    I made our boarding ladder in 2013 and used a simple dado joint (glued and screwed) to attach the rungs to the rails. It is still very rigid. The wood is mahogany and the hardware is from Davey. It is finished with the old style Cetol which has held up very well. It is not slippery when wet and we haven't found a need to add non-skid, but if we did, I would go with the clear self-adhesive non-skid tape.





    There are some more photos of it at the end of this album: https://www.flickr.com/photos/jdless...57640736587473

    THe mounting brackets are attached to a teak step at our lifeline gate that is bolted through the genoa track.



    Good luck. It's a fun project.

    Dowels at the bottom of the lower section fit into holes in the top of the upper section when the ladder is folded. This helps to eliminate any diagonal stresses on the hinges.

    Thanks Dave.

    Nice ladder : neat idea with the dowels also. I have the same hardware on order. Should be getting my hands on it very soon.

    Love your boat . We came aboard at the 2015 Port Townsend Festival....nice part of the world!

    I have basically the same ladder - but in unfinished teak. The steps have 1/8" (~3mm) wide grooves routed in them about 1/2" (~13mm) apart & 1/8: (~3mm) deep. Haven't slipped off yet...

    Hi Peter,

    I remember meeting you quite well. Although this year's in-person festival has been cancelled, the Northwest Maritime Center is hosting a virtual festival on September 12th.

    https://virtualwbf.org/

    It looks like a pretty good program and saves you a long flight. Hope to see you there.

    My friend Eric, owns Pélican, an Anthéa's sistership.
    He's very creative.
    He imagined a boarding ladder with a platform.!

    I like that! Bet it's pretty heavy though. Then there's storing it. Mine fits nicely under the forepeak hatch - which I really like.

    Thanks Garret and Gerard - the replies are appreciated.

    Gerard - your friend's ladder is a piece of art!

    I am hopeful that I will get my hands on the hardware soon and can get some more work underway ...and post some more pics.

    Dave - I would be grateful for a pic of your ladder in position on the boat. I have finally received the hardware for the ladder and will need to modify the design to be more like yours.

    I am particularly interested in how the ladder rests against the hull sides.

    Thanks in anticipation.

    A good ladder that gives ample support to a swimmer to board is really an asset!
    I like what you are doing here Dave and those ladders from France are just the ticket in that department as well. If one has a dog aboard that needs a walk on the beach, that one with the platform is tre's bon!

    Peter,

    We have a rub rail about 6" below the sheer, and the ladder rests against that. The step with the brackets (post #2) is bolted through the genoa track. It's on the port side, so not visible in this photo that shows the rub rail.



    It's important that the ladder hangs vertically to avoid lever forces on the brackets. I attached some spacer blocks to the ladder where it lands against the rub rail to ensure that it's vertical.

    Sorry, but I don't have any good shots of the ladder in place, but I'll be back on the boat next week and will post some photos then.

    We have a similar set-up with a rail cap and a rub rail. Here is a pic of our current ladder. It presents a bit of a challenge in getting out of the water after a swim- hence the need for a new version.

    Folded, it's a boarding ladder for getting out of the dinghy, and only extends down to the waterline.
    Unfolded, it's a swim ladder, and the 3 steps below the waterline are key to getting out of the water.

    The water is too cold for swimming where we have sailed, so it's almost always folded.

    You may want to add some weights to the lower portion to keep it from floating if you're using it as a swim ladder.

    Progress has been a bit slow of late but the ladder project is underway. The ladder steps have been made with the tenons left over-long for trimming later. The steps have been given 2 grooves to assist with non-skid properties.


    The sides of the ladder have been cut and step placement marked.



    The mortises in the ladder sides have been cut and fitting is underway.

    I love that ladder with the platform on it. A bit big for my boat but I'm definitely starting on a ladder project this winter once I get my shop set up in our new home.

    More progress on the ladder with non-slip grooves cut on the treads (top and underside for the part of the ladder that hinges down) and handholds cut in both parts of the ladder frame. The handhold positions took a bit of thinking about so that they would be in the right place whether using the ladder from a dinghy or from the water (swimming) . The parts have been given 2 coats of Cetol Marine Oil and Varnish before assembly. The main purpose here was to hopefully avoind any staining from the inevitable glue squeeze-out when the wedged through-tenons are glued up.

    The 2 sections of the ladder have been glued with wedged tenons to avoid screws into the end grain of the ladder rungs. Clean up with a plane and ROS has seen good results with the finished effect. Dry fitting (minus wedges) was necessary to ensure everything was coming up square. Photo quality is a bit variable.
