Interesting New Boat splashed recently

[Mister]

Stripping planking is nothing new, been done for years with multiple layers even stripped planked alloy all been done for years and is tried, proven and tested. Might have to wait a few (quite a few) years before this so called new planking is tried proven and tested.

Just mentioning the word "bog" has all sorts of conentations, most not good ones.

From what i was lead to believe, any motor with a gear ratio sligtly less than or equal to 2/1 would have produced much the same results. Etec was not specified, just what the owner ended up choosing.

The strip planking isnt "bogged" as such but 3mm approx of resin based glue is squeezed between each plank, then glassed over, thus producing numerous mini "ibeams" between the inner and outer skin. The only difference between the old style of strip planking that i can see is instead of glueing the edge of the plank before placing it in situ, the plank is placed first, then glued.

Each to their own but i rather like the look of the flat sheerline.

Where does the 3mm fit with the 30mm?

[Stewey]

Between every 30mm (i think) plank there is a 3mm gap. Tthis is where glue is squeezed into.

Hi there Mister 3mm tile spacers go between the planks, the planks are 30mm x 12mm for the PT21 and yes its not a new thing but the way its done on these boats is a lot easyer and less hassel than the old way with all the clamping and the bog or very thick glue mix is a mixture of cabosol and qcell and epoxy not your ordinary bog by a long shot and after all the strip planking is still only the core and the whole boat is a true epoxy composite no polyester and chop strand and ichy scratchy.

Just finished reading the whole boat build thread (has taken me a few days) lol but I am really impressed with the workmanship that has gone into making this boat well done to Dean and BMD. Cheers

Hi there marto78 yes a very good build hes a chippy and very clever ,the thing that impressed me was how he turned the boat over under the house by himself.

[stevemid]

I don't know if Dean is on here or not but did he ever say why he went against the designer's advice on gearing in the first place? Happy result but long way round.

[chris69]

hi steve yes it suited his electronic but just about all motors have NMEA 2000 set up now,originaly it was going to have a 150 yamy on it.

[chris69]

Just saw a clip of the boat test of the protournament 21 with the etec 150 and as the motor is still new and running in it got 42knots at around 4900rpm so still more speed to come out of this rig when 5850rpm is reached.

[Mister]

No doubt there will be a follow up when 5850rpm is reached, can't wait!

Just an update on the "splash" of this boat. Following is a link to the latest video on this boat. Link is to the website page and click on the video for the Pro Tournament 21. Happy viewing.
