Does anyone have a rough estimate of the number of M-36 still sailing?
Number of members on this site?

Tory Salvia We have 145 active members. 64 are M-36 owners. Mariner made 85 M-36 hulls. I'm hull 61. I've owned Sparkle Plenty since 2001. To see member groups go to MYOG GROUPS in the menu. (https://marineryachtsownersgroup.ning.com/myog-groups).

Erik R There are a bunch though that have been decently maintained and restored that are in very nice condition. I'm half way through doing a hefty restoration on mine to get it ready for sailing down to South America.

Erik R There used to be a list of all or most of them somewhere on this site with current owners. I cant seem to find it anymore but it never seemed like it was actively updated or looked after. It would not have been a complete inventory anyways as i…

I purchased my Mariner sans water tanks. I contacted Florida Marine Tanks and they said that they didn’t have the dimensions and the price would be outrageous for them to design and fabricate.
Has anyone had experience with using a bladder type…

James Porter My 1983 M36 had been fitted with bladders on both sides by a previous owner but they were pretty torn up. Rather than going back to a hard tank cleaned up both compartments and added partial bulkheads on either end to help keep everything in place…

Erik R Do you have a Mariner 36? A few years ago I inquired about getting replacement tanks. I gave them the tank # off of my old tanks and they said they could make them for me. I think they quoted around $750/ea if i remember correctly. If you have a…

Anyone know what was used for original floor varnish?

I did some restoration in the head area and ended up scraping the varnish of the sole in that area. I re-varnished it , but it turned out much darker than the original cabin sole which has a light honey color. I know this is a longshot, but I dont suppose anyone happens to know what particular varnish or finish they might have used on the original cabin sole of the Mariner 36's? OR, has anyone re-varnished their cabin sole on their Mariner and managed to get that light, warm honey color like…

Inflatable Dimensions for Mariner 39

I am looking to purchase a new inflatable rib (fiberglass/aluminum floor). My goal would be to store it on the foredeck during long passages. I am looking for something in the 10-11.5 foot range. Curious if anyone the forum has dimensions (length and width) of a rib that would fit on the foredeck. I’m about 5 hours away from where my boat is stored during the winter and won’t be able to measure the space for a couple of weeks. Thx!

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.

Seacock Replacement

Posted by Matt Moreau on October 28, 2025 at 11:48pm

Hi all,

I need to begin the arduous process of replacing my seacocks. Has anyone in the group tackled this project? If so, would you kindly share any best practices or tips? It appears that each of the seacocks are embedded within an area of reinforced fiberglass. Any guidance here? …

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

Posted by Joseph R Robert on October 19, 2023 at 11:02am

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. …
