From previous owner Matthew (Buzz) Hall

I have just purchased the "Pelican" from Tim, Mimi and Matt Riley in San Diego. The Pelican is still in San Diego, but I hope to relocate her soon to Channel Islands marina in Ventura County, Ca. 
The current information listed by Matthew (son of the previous owners) is correct and I would like to amend his comments. The Riley's have kept up the Pelican diligently over the years. My Daughter Tracie Hall and Matthew Riley have been dating for several years. I was offered the Pelican after the Rileys picked up another 36' sailboat and a 30' powerboat. I guess the boating bug really hit them hard. I am currently traveling every weekend from Ventura County to Pt Loma to make minor repairs on the Pelican before having her hauled out, having the bottom painted and surveyed before I move her to a new home at Channel Islands in Ventura.
I have never owned a boat before (but have done a little sailing) and really love the lines of the Mariner yachts. The Pelican is suffering from some rot on the decks but none of the rot repair looks insurmountable. Many areas have been re-built over the years. I am a general building and electrical contractor with lots of structural repair experience (on the building side). I have noticed the mizzen mast support looks to be less than what I would call adequate. I am trying to re-support the mizzen and front cockpit from under the deck and clear the area where the upper cockpit deck meets the cabin bulkhead of some rot without destroying the entire area. I have seen many of the documented repairs listed on the mariner web site but none that I have come across indicate the original design of the area just aft of the cabin bulkhead (with a Perkins 107 installed). For the life of me I can't figure out the original intent of the builders with regard to the support of the port side of the cockpit well and Mizzen mast.
I have my ideas but would really like some pictures of another M31 with the Perkins and associated support of the front cockpit and mizzen (from the engine compartment). I would appreciate any information you may have. If there is some one
local that has a similar boat and would allow me to look at the structure above the engine and supporting the mizzen (or send me pictures) I would greatly appreciate any information. I have included a few pictures of the Pelican at rest and interior shots.
