Tri-Cabin aft heavy

Greetings. Been mostly lurking since joining some time ago but have a question now. In the Leaking Salon Windows 36' Tri-Cabin thread Mendal, Aaron's father, made a comment that his 1972 Tri-Cabin was aft heavy due to the engine placement and utilizing vee-drives. Is that the general consensus? I have one of these and fixing it up. Haven't floated it yet.

Many makes and models have engines in the stern and use V-Drives or Out-Drives. They all are a bit heave in the stern, but it isn't anything to be concerned about. The boats run well. The trim tabs add lift to the stern and plane out the boat while crusing.

greetings. the f-36 tri cabin with the engine aft design ( it was changed in 1979 to mid ships under salon) is always slightly stern heavy at rest. that is the quirk of this particular design. if at some point, the back cockpit deck is rebuilt, depending on the materials used, it will be even more so, but, once underway, using the trim tabs will always get her up on a fairly level plane. after we got her in 1972, whenever we washed her down, we always noticed that the water in the salon window channels would collect in the back corners, hence the fact that dad drilled extra drain holes to allow for more drainage.
if you have any more questions, feel free to ask. if i cannot answer them, ill inform dad he needs to get back on and 'talk' to you all.

Using four blade props will also give more stern lift while umderway.

I don't think its anything to worry about , trim tabs would take care of any issues . also so how you store your gear . I would much rather have a stern heavy boat then one thats bow heavy as trim tabs will help stern heavy boat but there is not much you can do with a bow heavy boat . I wish my F36 (conv)was heavier in the stern .

I am not sure what year the moved the engines midship but I do know of a 1977 that is mid ship . there could have been a over lap or made in diffrent areas PA/WIS/CAN.

in late 1977, for the 1978 model year, the design was modified to a flush deck style, although there were still some 'cockpit' tri fly models made until the complete redesign cutover was made. the tri cabins were never made in wisconsin as part of the carver line. the shepherd boat facility made a majority of the f-36 tri cabins with the cockpit until the production was shifted to the elkton maryland plant for the ''new'' flush deck model. these were made until late 1987, when the f-36 tri cabin went out of production. the cockpit versions, always had their engines mounted aft, under the two bunks, but, when the flush deck version was made, the engines were shifted to the mid ships area under the salon.
hope that clears up some of the fog.

hi paul, okay here goes for the f-36 tri cabin evolution. in late 1977, for the 1978 model year, the tri cabin became a flush deck vessel...... the aft cockpit was disposed of and the back deck raised to form a flush deck. the aft cockpit was retained for the 'tri fly' version for the remainder of the 1977/78 model year. for late 1978 and beyond, the 'tri fly' version was abandoned and the 'flush deck' version was retained with some modifications (aft port lights in the aft cabin for two years followed by sliding windows, the forward cabin portlights were abandoned for the 1982 model year and just being retained for the forward head). the tri cabin was made until the 1987/1988 model year, then shut down. the flush deck version was made in elkton maryland from 1977/78 until production of the model ceased. hope that clears it up. to compare the different versions of the tri cabin, do a google search for "1972 trojanf-36 tri cabin" (cockpit version) "1979 trojan f-36 tri cabin" (flush deck version) "1977 trojan f-36 tri fly"

The pic in my profile is a 1985 'flush deck' tri-cabin although, I hadn't heard the term before.

hi paul, ready123, greetings from tampa.... yes, out on the road again. paul, would you mind posting the email i sent you with the tri cabin evolution and the pics to go with them? i have tried all morning long to do that here but for some reason i cannot do it. if you figure it out, i would really appreciate it. on another note, for all you animal lovers out there, do a google search and a youtube search for 'sam the koloa bear' that was rescued by a firefighter in australia....... she gave him her injured right paw while he fed her 3 bottles of water. it will really bring a tear to your eyes.
what a great story that is.
thanks again paul for the help.

Just sent koala bear rescue story to some friends the other day. Better than the political crap that flies around.

A very nice animal story for a pleasant change of pace....
