tri-cabin owners proof read

[aaronbocknek]

talkinga bout fuel tanks, my trojan was converted (twin 454's) in 2009 and i have 4 total tanks with "80 GAL" stamped on them.... was that an option or did the PO add those?

what year is your tri again? when the redesign took place, according to the 1982 brochure i have, extra tankage could be added under the salon as wing tanks, additional to the tank under the center aft berth or under the two p/s twin berths on the 77-80 models. i do not recall any of the flush deck tri cabins having this option though. if your tri is pre flush deck design model year the extra tanks were added by the PO.

its the 74 model, there are twin tanks on each side (identical tanks) in the main saloon which in my pinion is a VERY idiotic design, as it makes it vertually imposible to get anywhere behind the tank (such as the shutoffs) water and septic system along with all hte piping back there, theres simply no acces to it due to the tanks...

the original set up was two wing tanks, 75us gallons each for a total tankage of 150 us gallons. if i recall, there were not one but 5 shut offs, facing towards the keel, accessible through the genset access hatch. one for each engine and the other for the genset, which used the starboard tank to draw from. the other two shut offs were in the two rear engine areas, copper fuel lines and shut offs mounted on a block of wood facing forward. but, remember, the 1972 f-36 tri cabin was nearly a prototype and that particular setup might have redesigned in later years. on my tri cabin, 1983, i have a shut off on top of the tank under the centerline aft berth, and 3 shut offs on the forward bulkhead in the engine room. one for each engine and one for the genset.

Aaron,

I always enjoy reading about the history of your parents Tri-Cabin... My boat (hull 440-2763) had the storage features you mentioned, but made do with the original windshield design. She had the optional teak aft cockpit covering boards and toerails, and factory teak swim platform (clever in how it blended with the hullside spray rails). And there was one more Sea Raider carry-over... all '72 model boats had solid teak helm stations. This changed to FG in '73.

BTW, according to Don, that '7' in the hull number indicated that the boat was floated across the U.S./Canadian border as opposed to trailering across (I'm thinking this had something to do with Customs duty and taxes?). Interesting, I thought.

ok my set up is TOTALY different, i gues the PO when installing the new motors in 2009 changed that up as well....
there are 4 shutoffs that are located ontop of each tank (virtually impossible to access), there's one on the forward part of the engine compartment for each engine and one right next to the gen-set which draws from the PORT tanks instead of the STBD and then on the aft deck (outside) when you lift the storage hatch theres a crossover shutoff for the fuel (go figure why the hek thats all hte way out there)

what i cantfigure out thou is which tanks are the primary tanks that the engines pull fuel from... i mean i fill all 4 tanks (4 seperate fill holes) and it runs but the question is which tank is the primary (id figure it would be the aft tanks first) and the boat has a fuel transfer feature but none of it is labeled so no clue what switch does what .... i know its kinda sad

hi jon, you bet. that teak helm station was absolutely beautiful and was one of the selling points for mom and dad. for a 'fiberglass' vessel, we sure had a huge amount of teak, but, when washed and dressed, it looked absolutely gorgeous. and you are so right about the blending of the platform to the spray rails. a true unique mark of the 'canadian' tri cabins. shepherd always blended them that way. i've never seen anything like it since. just a small touch, but, that little detail really set it off. one of the best days of my life was sitting beside the swim platform 'forming' guy at the shepherd plant the day bubala 3 rose out of the mold. in his late 60's, a mild mannered canadian man with a non lit pipe in his mouth. he explained how the teak was cut, steamed, formed and molded into the swim platform. i actually still remember the smell of the fresh teak---intoxicating! he said to me, ''you know what, i'm working on the platform that's going on your mom and dad's boat. i hope you and your sister enjoy many a summer day jumping off of it when you are at anchor.''
memories.
