Need help.
I have a Mariner 36' sloop, 1979, I live in Melbourne , FL.
The last hurricane this fall, 2024 bashed up my bow at a hard dock slip.
Does anyone have the dimensions for the bowsprit and/ or have a starboard bow/mooring chock or know where…

Wiring Question

In the bilge of my Mariner 39 I have a wiring harness (I think that's what you call it) that connects various wires (ex navigation lights, wind instruments, etc.). See attached photo. I am looking for a better solution as this approach seems rather flimsy.Any thoughts on a better approach?Thanks!

FYI: Had to replace a cracked plastic 90° elbow on the bottom of the starboard aft water tank on our Mariner 39

Earlier this year, I was putting a new gasket on the top of the starboards aft water tank (like I did for the aft holdign tank a few years ago), when I dropped a socket down the front that I could not reach from the front. We have an access hatch on the side and when I openned it, I noticed the plastic 90° elbow on the water was cracked. We replaced it with a metal 90° elbow and hose. We had already replaced intake and vent hose.

Sailing Polar for Mariner 39

Does any one have or created a Sailing Polar for Mariner 39. All major/real weather routing apps (i.e.,Luckgrib, Predict Wind, qtVLMm, etc.) need sailing and motoring polars to be more accurate. I've been using a modified Valiant 40 (also tried Passport 40 but it's faster on numerous wind angles). If so can you email me a copy (jashmun@gmail.com) and if possible post the on the group? Thank you!Juliasv Esprit (#27)Currently in Curaçao (for hurricane seaon)

Who made mast on M36?

Anyone have any idea who made the mast and boom on the stock M36? I have not been able to find any manufacturer stamps or labels on my mast, and have not figured it out trying to trace the profile and matching it on sites like Rig-Rite.

M39 Hull Thickness? ... Sizing thru-hull fittings

Hi all,I'm getting ready to replace thru-hulls (which are all original) on my Mariner 39 with TruDesign fittings. I've heard the hull is 2"+, which would be too thick for the skin fittings I bought. Snooping around the forums, it sounds like it's under the engine where it's that thick, but thinner elsewhere?Can anyone confirm hull thickness?While I'm at it, any advice on replacing the thru-hulls specific to the M39 is welcome. Other than I need to grind the original ones out of the fiberglass..…

Filler used inside of bilge?

Has anyone ever dropped their keel on an M36? I'm wondering how thick the glass layer is on the bottom of the keel stub, and how thick the layer of filler material is that they added in the interior bilge compartments?

Need information on dropping the rudder...

Posted by Julia Ashmun on February 5, 2025 at 1:49am

Hi Mariner owners, I’m about to haul-out to drop my rudder to replace the 304 stainless with 316 and have a few questions:

1) Mariner 39 owners, does anyone know the full length of the rudder? As in, can I drop the rudder while the boat is on jack stands vs raised in the travel lift ($$$)? Digging a hole for the rudder to drop into is not an option at this marina.

2) Any skeg mounted mariner owner: wha are the steps to drop the rudder? How hard is it to get the bottom bolt and/or…

Engine Guard - M39

Engine Guard - M39

One improvement that I am really happy with is the addition of an engine guard. When working on anything on the far side of the engine, this allows laying on top of the engine without risk of damaging the small fuel pipes. It is made of 1/8" steel. It attaches with 3 screws for easy removal to work on the engine, but remains in place for normal operations. …

Complete Engine Rewiring - M39

Over the last winter, I completely rewired my engine. This was prompted by finding some scorched wires at the control panel, and later learning that the original design had a couple significant and even dangerous design flaws. This is just a summary, but if anyone wants details, feel free to ask.

Key points:…
