Previous blog posts have mentioned the infamous dinghy davit project that spanned two years. This blog covers the intricate details of the massive project. As with all blog posts, Hilary is the author and will preface this post by saying how excited she is to document this project which showcases just a few of Bert's many talents. Bert is truly amazing and Hilary is excited to document and share his project journey. Each of our boats had a dinghy. Rain or shine, we very much enjoy relaxing dinghy days and many "Sunday-Funday's" have been spent in the dinghy. Thus, equipping MMS with a davit system for our dinghy was a necessity.

| A rainy dinghy day a few years ago. |

| Chilling in the dinghy, visiting with friends. |
When we purchased Make Me Smile (MMS) in March 2023, her original 2006 fiberglass swim platform was cracked and rotten. Additionally, she had never been equipped with davits for a dinghy (aka tender) nor a dinghy launch/retrieval system.

After purchasing MMS, we put her on the hard in mid-March 2023 to address a series of maintenance items, including replacement of the swim platform. Bert located a local fabricator in Cape Canaveral to custom fabricate a new swim platform and swim ladder for MMS. Bert also located a custom builder of davits on-line. Measurements were taken for both, designs were created and approved and orders were placed.
Upon delivery, the custom swim platform exceeded all our expectations!!! The fabricator even included installation. Having the final installation included was a big relief to Hilary as it was a bit intimidating to her to potentially be involved in securing the new swim platform to the transom, especially considering the new swim platform also needed to support the dinghy.

When the crate containing the dinghy davits was delivered to the yard, we were disappointed the stainless steel was not polished as depicted in the images on-line. Sigh....... yet another challenge to navigate as neither of us would be satisfied with davits that were not polished. Polishing stainless steel was a job Hilary could handle, allowing Bert to stay focused on more serious mechanical maintenance items. Bert ordered a tube sander for Hilary and many, many weekend hours were spent polishing the davit tubes. Three passes were made with increasingly fine sandpaper before applying the polish. The sander looks a bit intimidating, but it was definitely the right tool for the job.

After four months on the hard, we launched MMS back in the water in July 2023 and brought her home to our slip in Harbortown. We were able to park our former boat, Simplified, in the slip next door to facilitate our move from Simplified to MMS.
The winch system to mechanically lower and lift the dinghy had not been installed yet. Even so, the transfer of the dinghy from Simplified to MMS was expected to take less than an hour. However, it became evident very quickly that lifting the dinghy manually was going to require some serious rigging. We are very fortunate to have a dear friend, a retired fireman, professionally trained in rigging. It took a full day to get the dingy rigging (version 1.0) configured to lift the dingy out of the water and two men using a lot of muscle to get it lifted. The rigging anchor point was the base of the radar mast up on the bridge. This created a trip hazard on the bridge and also prevented pivoting the mast down for low bridge clearances. Not a big deal in 2023 but a very big deal in 2025 for navigation of the Erie Canal. We need to be shorter than 15' to traverse the western section of the Erie Canal which means lowering the radar mast.
 |
| August 2023 - Beginning of the day: Bert deep in thought on how to install rigging to manually lift the dinghy into place. The winch to mechanically lift the dinghy had not been installed yet. |
 |
| End of the day: Temporary rigging version 1.0. Several ratchet straps were used for the first lift of the dinghy onto the new davit system. |
 |

Temporary rigging version 2.0 quickly replaced the ratchet straps with sturdier, stronger lines to hold the dinghy in place until the cabling system and mechanical winch could be installed. The original design of the davit system had the winch attached to the dinghy davits. However, once we started using the dinghy, the tension on the winch was unacceptable. Bert got to work creating a new design to change the pivot points of the cables to reduce stress, spread out the weight load for lifting/lowering, and also to move the winch up to the hard top on the bridge. Suffice to say Bert spent many, many hours, days, weeks using complex math that is far beyond Hilary's capabilities.

Fast forward from the summer of 2023 to early 2025. Bert completed designing the permanent winch and cable system on paper. Time to begin manufacture of parts and prepping MMS for the permanent installation. The two permanent anchor points for the winch and cable system are on the hard top, requiring reinforcement. Prior to departure from Merritt Island, two large areas were drilled, the balsa wood was ground out and replaced with poured epoxy resin to ensure enough strength to support the entire system.

With the hardtop reinforced and the anchoring system for the cables in place, Bert was ready to install the winch and cable system. After the cable system was installed the temporary rigging lines were removed. We can now lower our radar arch to move through the Erie Canal. Additionally, with the radar arch tipped down, Bert had access to replace the original, non-functioning TV antenna with a new one. Yea!!!!!

With the permanent cabling system in place, Bert's focus transitioned to moving the winch from the dinghy davit up to the hard top. This also required running electrical to operate the winch and installing the plug for the winch remote control. In the picture above, you can see the new winch installed on the hard top (black cover on it). The post directly beneath the new winch is where Bert needed to run the electrical wires down to the engine room. This required Bert to custom fabricate yet another tool. A 5' drill bit to drill through the hard top and transom at the top and bottom of the post. Yes, a five foot drill bit!!! Stores don't sell such a tool and necessity is the mother of invention. Bert rode the eBike to the hardware store, purchased a long piece of metal conduit tubing, brought it back to the boat and made his own 5' drill bit.

With the dinghy davit cabling and mechanical winching system fully installed. There was still a bit of clean up required. The temporary winch that had been on the dinghy davit for the past two seasons was cheap and had rusted. Bert cut the old winch off and it went to the dumpster. Hilary then set to work with Barkeepers friend and removed the rust from the dingy.

| No more rust. Barkeepers Friend is an amazing product. In addition to removing the rust from the dingy, Hilary polished the dinghy davit too. Nice and shiny once again. |
Once complete we treated ourselves to a short dinghy ride up the Hudson. In the midst of completing this massive project while we've been at Albany Yacht Club, Bert also completed the required maintenance on the dinghy outboard motor (oil change, impeller, spark plugs, etc.). She runs beautifully. We can't wait to complete our journey to MI and are looking forward to many dinghy days on Lake St. Clair this summer.
If you are wondering when we will be underway, we believe we will start moving Thursday, weather dependent. There are still two locks on the western Erie Canal that are not open, but the major repair of the earthen embankment between locks E-16 and E-17 is holding so we are confident it is time to move forward and through that section of the Erie canal.
