offshore bracket

Moving outboard back GOOD or BAD ?? http://www.dusky.com/static/sitefiles/p ... s/dds2.jpg
Do any of you think the transom wont hold up to the added pressures. I have Suzuki 70 hp

Bad for sailing! It moves your center of gravity aft and center of mass father aft and larger.

thanks for the reply you are the first to respond since my joining this forum
I was planning on using the floatation kind of bracket. have you ever heard of anyone doing this confluence

[Wayne nicol]

just curious- what are your reasons for doing it?
space?

[seahouse]

If attached properly (backing plates and bars to distribute the load) the beefy transom on an M should have no problem bearing that motor and bracket. I would think that clearance for full rudder range of movement might be an impediment though. Have you designed it for that?

I disagree with "Grady" I think the Armstrong brkt shown above with a swim platform it does four purposes #1 as it is formed into the shape of the Hull it actually extends hull length which is better for sailing & better fuel economy when powering , #2 it also acts as a floatation tank so ur engine weight has less effect on the transom which helps for sailing , #3 also has a built in swim platform which is great for boarding on /off on an M & also would allow in my case easier raising of the larger engines out of the water without having to raise my helmsman seat, #4 will give the boat a better holeshot when getting up on a plane , should also allow slower cruising speeds with improved fuel economy, I've been researching & studding these for some time now & think these r the best all round benefit for anyone considering installing a jackplate this is the way to go other than the cost of the them "pricey"
Now if we could get 6 guys to buy together I,m sure we could get a much better deal

Just sayin thats all

I like the idea of a swim platform, easier boarding, etc, but as Seahouse says, you need to evaluate your rudder clearance/rigging issues carefully. If you can make it work it would be nice. And, if Highlander likes it, it's gotta be a good idea.

Very interesting, I'll be following this one.

Is the steering mechanism built into these? How would it affect trailering?

The way the picture looks to me is that it will extend the hull only in the center. Once you heel over the hull will be basically the same length. The farther away you move mass from the center of pivot affects the energy it takes to perform a tack. Once again it is a balance between sailing and motoring. Just depends on what is more important to you.

sweet lets get 5 others i am ready!
I am very interested in what you have dug up in your research
do you know the degree angle the M has hull to transom ?
and how far back would you push your big motor? confluence

[confluence]

Grady,
taking into account what you said about the center of gravity. Do you think it would help off set the bracket if i used the forward flotation hold for fresh water tank ?
( keeping the foam in the boat of course ) confluence

[confluence]

Jimmyt,
just how beefy is the transom on the M ?
I'm sure backing plates are a must, but how much do i need to add to be sure the load distributed appropriately
I do plan on supporting the bracket all along the top edge


GUYS has this been done or am i " braking water " here confluence

[Jimmyt]

You may be confusing me with Seahouse; who posted that the transom was plenty beefy. Several folks on the forum are running 90's on them, and I haven't seen a post where the transom has been ripped off of a boat (fairly sure someone would have posted it if it had ever happened...). Most of those brackets appear to actually spread the load over more area on the transom. I'm running the stock setup with a 60, and have yet to drill a hole through the transom, so I'll leave the "will it hold it, and how to reinforce it" questions for others. I just like the idea of a little more boarding room and a swim platform. As pointed out above, steering linkage, rudder manipulation, etc will need to be worked out. This will be a project that brings several projects with it. Good luck and post pics.

Thanks , I did confuse the author sorry. However your input is very helpful. Yeah its going too be an extensive project, but worth it I think. The COMADOR is on board with this mod( or would be if its easier to get on and off the dock) confluence
