When I was on holyday I found an Italian beauty and took her home.....
Found her a new boyfreind and gutted her "Gert Style "
here some pics. !!

Style and grace, Gert, Style and grace. Need more pix of the interior. Seeing the varnished pieces I want to see where they go.
I'm as envious of your shop as I am your work. Zowie.

Very nice Gert!

As always, Gert, you're the consumate craftsmen and quite the magician to boot...

Gert

How about you move your shop to the good old USA.

That is just wonderful. Another great looking boat. You do amazing work.

Looks great!!

Rolled or sprayed?

Looking to roll my 25 in the spring.

Looks Great! What's the color?

Sending my greetings from the Lost Sailor boat shed. It's like your shop, only different!

I saw the title, I saw that Gert posted it and knew it would be great.

Fantastic.

I hope to share some pictures in the next few months of my B20 Bahia project coming to a close.

Take care my friends!

Ian.

Wow Gert! You really are a glutton for punishment!! Nice job.

another fabulous job Gert

Gert....of course you realize that you are just setting yourself up to be kidnapped by me and sentenced to hard labor on my boat !!
beautiful job !!

Pretty Work

Thanks guys !!! :) dont forget it is my job !!

The colours are stark white and sky blue , this is the fist coat apllied with a foam roller , next and final coat will be brushed..

Two new crusader powerpaks are underway from your side , and the teak varnished , are the cabinets port and sb on the inside.

I will keep you guys posted !!

Gert

You sir are deeply afflicted with the boating curse.

Pretty work as always, keep us posted

I always wondered if the quality of Riva is better or worse than Bertram--is there any difference?

Always thought Bertram should have used stainless window frames like Riva.

Gert,

Wow, what a beautiful little boat, and an amazing gut job. Does anybody know the history of the 25-26 Riva's. Did Bertram contract Riva to build these boats? Is it the same hull as the 25 Bertram? Although I love the 25 and 26 Bertrams, I really like the way the front windshield is curved on the Riva. It makes this boat look much more like a little 31 Bertram than the square front windshields on the smaller Bertrams.

Like everything else you do with boats, I'm sure this is going to come out first class. Thanks for the pictures. Please post lots of pictures of the finished product.

Bertram licensed Riva to build 20 foot Bahia Mars and 25 foot Flybridge boats----the 20 looked the same as USA versions---25 were modified---I think all the 25's were v-drives.

Just copied this off the RIVA website.



The first two Riva models in composite material were born: the day cruiser Bahia Mar 20’ and the cabin cruiser Sport Fisherman 25’. The new material was first accurately studied by purchasing the hull from the Bertram boatyard. The hull was subsequently redesigned and both models were then finished with wood details, in line with Riva's tradition.

wow!

Beautiful work Gert.
Can you run us through your painting process and what products you used ?
Thanks in advance.
John

Just beautiful. Nicely done.

From one of Gert's posts

"And of course Dick , it has been brushed , but Awlgrip will also go nice applied with a fine foam roller , but very important for this paint is use 10-15 % reducer an apply it below 75 Fahrenheit and the moisture in the air must be below 70 %. "

Gert:

What are you putting in for engines? 5.7 Crusaders? Where did you purchase them over here?

Gert-
I ran into one of Carlo Riva's old captains a couple of seasons back http://bertram31.com/newbb/viewtopic.ph ... iva#p71328
I was told that Riva's B31 had "Riva V-8s" which were raw water cooled Crusader 454s with intake and exhaust manifolds of Riva's spec. I was also told that the boat was "gone over" at Riva and they replaced all of the hinges, latches, etc. with the stuff Riva sourced.
Good work and good luck!

What was that flash of lightning - oh that was just Gert starting and finishing another awesome boat redo! Holy smokes Gert do you ever get things done when you set your mind to it!
What a job your doing please keep the pics coming, Wow is right.

Gert, you present us all our ineptitude on a plate ,your workmanship is truly that of a master craftsman, to say I`m jealous would be a massive understatement, I hope that somewhere in your shop there is someone leaning your skills, so your tradition is carried forward, your photos are an inspiration to the rest of us ,please keep them coming, I love seeing these projects come together,it helps keep me on track with mine

What materials are Riva manifolds made of? Their profile gives a little more room between the engines. I was told that it was some alloy and not cast.

Few pics of another restored boat---

I do not understand the seemingly odd bottom paint.

Seems that it abruptly stops about 3/4 the length of the hull. It was in Gert's pictures as well as these. Definately not painted with the water line.

Is there some requirement for multi-colored hull bottom in case of capsize?

Curious...

Ian.

Good eye, Ian; it appears that the painted area is consistent with the wetted area when the B-25 would be at plane. Maybe a drag-reducing coating? How 'bout it, Gert?!?

I bought them at our local Riva / Crusader dealer

Carlo Riva spend a lot of time at the Criss Craft yard and they did some things together , he went over to Dick Bertram to have a look how fiberglass boats were build ..
Bertram was tired of the (very nice) expensive curved front windows and made the 25 with straight angled ones ... Riva changed it back ( to our curved ones ).
He also changed the fly bridge window from positive to negative , to create a better wind deflector .... this was also harder to make..

Sanded it grid 240 , then epoxy primer it to get rid of all the silicone and have a good base layer, after that sanded it 360 for the first coat of Awl grip

They are made of copper.......

Guys , this a tipical Riva bottom paint job , even the wooden ones have this , in the old days they used white gloss paint instead of antifouling.

sorry 38

I would have thought that Copper would be too susceptible to corrosion… You're sure it's not Cupronickel or Monel?!...

I never knew about the white forward and red aft bottom paint for Riva's.

Learn something new everyday.

Ian.

Gert,
Any photos of the finished interior?
Would love to see it.

Steve

Not sure if Gert monitors the board. It has been a while since he has been on. He does respond to a PM.

Hi Guys , it has been a while , kind of busy,,.....steven here the link
