New Member and my 21CC Mods

[Push&Pull]

Hello all.
I just found this site looking for the sealant to use on the Triumph. It's a great site. Lots of great info from everyone. I live way down at the southern tip of Florida and I am in the process of making some radical mods to my 21. I Bought the boat new and removed all the hardware and fittings. I want everything thru bolted. I built a custom aluminum transom motor bracket with 30" setback, that is full floation and I am currently getting it powder coated before I install it. I am using a Honda 130 engine. The bracket will have a hydraulic jackplate and concealed harness. I am redoing all the wiring and making everything waterproof and sealed. No running lights or gauges and minimum electrical, All electronics portable. I want absolute maintenance free. I'm rigging it so it could be swamped, pumped out and still run. I like going far offshore. New larger bilge pumps more foam, etc. I hope to have the boat done in a few weeks and ready for a sea trial. The bracket was quite a challenge considering the weak transom. It should give the hull more strength, better lift, performance and enhance diving and fishing access. I will keep everyone posted and add pics as It nears completion. Glad to be part of the group. Bill

Glad you found us and welcome aboard Bill. Sounds like you're making some major changes. We look forward to seeing the finished product.

Mee toooo, can't wait to see the mods.

I have some pics of the engine bracket during initial mockup on my 21CC. I put them under - Photos / General Modifications.

Here is a picture of the transom/splash well area of the 210.

The foam in the transom area is a very high density and is reinforced with rebar to support the rated engine weight.

It will be interesting to see the final results of your modification Push&Pull but folks need to realize that this will definitely void your lifetime hull warranty and Triumph has provided this caution on doing this:

We would not encourage people to do this sort of modification. As you can see in the attached photo the knee brace kiss off at the bottom of the buckets and most of the transom was removed in the process.

I dig the mod and I am sure you have figured out how to re-seal the inner hull. I only had a couple of questions in regard to the project. First would be how did this affect, or what have you done with the scuppers in doing the new mod? I understand that the boat is now considerably longer and does have far great bouyancy aft due to the added extension. My question is, Is the added length and bouyancy aft going to help or hurt with the over all hydro dynamic hull design? It is to say that using a full transom wide extension on this type of boat may be better served with a larger motor 175. My initial reaction to the design was actually for a small set of twins off the back. I guess my last question would be, did you explore the option of building a bracket that was designed for center extension only, leaving the sides in their normal spot and only relocating the motor back further.

[Push&Pull]

Yes I did consider the use of twins, but due to the weight and the inferior structure of the transom I decided to go with a single. I do believe your suggestion of using more power would surely be a benefit. I already had the honda 130. I may choose to step up to more power after I see the performance with the 130. I bought this bought 4 years ago and it sat around for a couple of years before I decided to put the bracket. The 21 was the largest roplene boat made then. The bracket provides me with a bit more room and function. I had another boat I was using and I finally got fed up with fiberglas and went back to completing the 21CC. The Aluminum reinforcing box I used to replace the splashwell is a 100 ties stronger than the roplene structure that I cut out and it is completely bonded and sealed in place to the the hull and to the bracket. I even have a lid on top and use the compartment to mount my hydraulic pump for the jackplate. I plugged the scuppers as they were all but ineffective anyway. (more water came in then went out) Most small boats do not sit high enough above the waterline for effective scuppers. That's what bilge pumps are for. I also installed a drainplug in the bottom of the hull that selfdrains if the pumps fail. One note. I had a 25' cat and if they ever make a Roplene Cat I will buy it no matter how much it costs. I've owned over 30 boats from 18' to 36', all offshore use and the cat design is far away the best. I'm just sick of maintaining fiberglas. Sorry for the long post.

To answer NC angler. I agree, I would not reccommend this mod to most users. It was a very difficult project due to many unexpected issues with the Roplene hull design. (expensive too) Besides, Triumph now has the 23 that looks fairly impressive. And yes, it surely voids any warranties. But this was the fourth boat I have modified by adding a bracket and I have been pleased with the benefits obtained on all. It suits my needs.

Great post Push&Pull

Like many of us have said, over and over, there is no such thing as the perfect boat. To our family, the 210CC was as close as we could get to perfect -- for OUR family. We understand that it may not work for others, but as long as it works for us, that is all that matters.

We really like your pictures and the modification to date. We also fully agree on the scuppers. What a waste -- we plug ours up before launch.

Looking forward to additional pictures as you put her back together.

I am a long post kind of guy myself too. I do have to agree with the scupper comment you made. Unless the boat has some serious scuppers they never really work right. I have been contemplating adding another bilge pump to my boat also. I have had a couple times when the extra bilge would have really gone a long way. I will be really interested to know how the boat performs and reacts to the new transom and motor. Please keep us posted on the progress of it. I have worked on all sorts boat projects with friends from bracketed singles and triples to diesels, but this one is really cool and different. I am a big fan of the wiring concept you are using on this boat also.
