Honwave GPR seat

Hi!

Have brought a new Honwave 38 IE, and a freshwater used Yamaha 9,9 from 2002.

Into this boat there is a GPR seat, and I would lik not to use it. And instead use the Trem seats I have brought:

Does anyone know if the Honwave boat need to have this GPR seat mounted to make the boat/construction stiff enough?, or is it ok to use the boat without it?



Have also adjusted the engine a little. Removed a small metal part from the trottle system so it open 100%. And then adjust the reedvalve to 15ps spec (6 mm opening each side). Engine is much more powerful from idle and all the way up.

Fred

You will be fine without it. Enjoy!

I have a 4m alu floor Honwave and do not use that bench. I use a launching roller for both launching and seating inside.
Show us a pic of your boat with the Trem seat! Is it the 40cm diameter one? How do you fix it?

Hi!

Thanks for nice and positive answears.

I did buy two of the TREM 80cm x 30 cm.

For me they fit perfect inside the boat, I blow them up to around 50% pressure, fit them between the tubes in the boat, then I fill them up to 100%. Then they are completly locked between the tubes, and slightly lower on the top than the Honwave tubes.

I can`t tak any picture now, because boat is into my campingcar(with lots of snow on and around). Give me a couple of months and Ill make some pictures

Today I did find my Honwave again. New, only tested once before winter.

But when it was correct packed in original bag and stored in the garage into my camper I did drive around 200 km before I could blow it up..
On this time I have got a hole in the boat because of the transport....

My last boat was a BRIG and this was with us on holyday in Croatia with no problems with the rubber/nylon skin.

Is the Honwave skin bad quality?


And how to repair... Look not so easy for me on that place.....


Cheers

Is the hole from friction, puncture or is it a crack from flexing while at a low temperature? What was the temperature when you were driving with it in the camper?

It must be from staying in original bag into the camper when driving. Must have been "some flexing" Temperature 12-20 celcius.

Strange, the boat was dry, no air into it, packing it like original, staying quiet into a camper garage like the Brig I had, and this happends...


How to repair?? HEEEEELP.....

You will probably have to lift some of the edge area of the rub strake and the handle to get a patch on it. The crack probably occurred at that location because the surrounding handle an rub strake must have created a stress concentrator at the fabric between them.

I am assuming that that you meant minus 12-20, rather than plus 12-20. I'm not sure at what temp PVC fabric becomes brittle, but it probably is somewhere at the lower end of that range. Hypalon stays flexible well past -40.

Hi!

Thanks.

Seems to be a really good Idea.
But to lift the rub strake and handle I mut make the glue hot I guess? so I get them lifted from the aeria around the hole, and put a patch there.

But how much heat is needed? Hair dryer or a Bosch heat pistol??.

When adding heat on the parts, is the rubber parts easy to lift off?

Have checked this out now. This damage has to be repaird from the inside.

A spesial workshop in Oslo must make a "working hole" in the tube, repair it from the inside, and repair the big hole at last. Was normal repair he said. Will cost me around 2500 NOK or a little less than 300 euros.
