THANKS!
I didn't expect such a detailed answer! I guess everyone in the GP26 scene is aiming for minimum hull weight, so 1000kg should be realistic. I saw a ORC certificate of a similar boat, a bit wider and heavier, and looked for something to compare with to get an idea of the speed potential. |

QUOTE (Kevin Farrar @ Sep 18 2009, 12:23 AM)  Hi Persilz, I did a little review a came up with a imformal guess. Measured wieght includes internal ballast (7% of hull wt. in measurement trim) and Batterys (2% of hull wt. in measurement trim) this measured trim weight can be between 1000 and 1100 kg. A guess of all the stuff excluded form measurement should weight approximately 73 kg. This would included items such as sails, outboard, anchor with rode, first aid kit, flares, fire extingusher, fenders, dock-lines, loose navigation gear, winch handles, tools and spares etc. I figure another 8 kg of personal gear for 5 crew and 5 kg for food, water, beer and of course red wine. So sailing wieght should be about: Hull in Trim 1000 kg excluded gear 73 personal gear 8 food and drink 5 sub total 1086 kg crew wieght 340 Total 1426 kg Add another 100 kg if sailed at max Hull wieght. Kevin, You have underestimated the allowance for red wine!!!! |

About 1 meter to go!!! I Have two pieces in the oven so I am keeping this short.
BTW 1 kilo should be plenty of red. Kevin

Hello All,
Pretty sucessful week. Thermo forming of the corecell below the chines is completed. The Mylar template of the topside panels were drawn, checked, redrawn and the foam for topside panels cut and glued togeather. I finally got around to trimming the rings for two of the bulkheads and they are now set in and curing. Tomorrow I hope to start cutting the unidirection e-glass for the topsides. Like Jim's 20 footer I'll be laying the topsides up and vacuum bagging them off the boat. This process should start in a few days. Kevin

Ok Ok
Mid week up-date. Yesterday we cut the 176- 90 degree pieces for the topsides. The 12- 26.5 foot 0 degree peices still to go ( no biggy ). The 90's were cut on the Gerber sail cutter. Each topside surface needs 44- 7.25" peices none of them over 2' in length but each growing by 1/8" from aft forward. Using the Gerber and AutoCad for the layout it only took a hour and a quarter. It would have sucked doing this all by hand. Thurday night (if all goes well) is interior topside laminating night. Kevin

Friday Morning
A heart felt thanks to Geordie and Bill for thier help with last evenings laminating session. The pump is still running this morning about 13 hours after it started. My guess is that I'll let it go untill the resin in the mixing pots stiffen up a bit more - another 4 or 5 hours. The "hot coat" was done with a mix of Ampreg fast and extra slow hardened with the laminate being mixed with just the extra slow which gave us plenty of time to do it right and also consume a modest amount beer. The next step will be to router the rebate along the edges of the outer surfaces and then do the outside laminate which is the same as the interior side. After this is done I'll trim the topsides chine edges and fair both the topside chine edges and the round bottom chine edges to get a good fit and glue the nealy finished topside panel back into the mold. My goal is to have the second lamination completed this next week and the placement of the topsides back into the mold next weekend. Kevin

Monday Morning Update
The topside panels are laminated inside and out and this morning I spread a layer of micro-balloons on the exterior topside surfaces. This layer should go off by this afternoon and I'll move the panels back out into the shop area. While the second panel was being bagged yesterday I started making patterns for the inside skin laminate for the hull below the chines. Kevin |

We managed to get the two topside panels installed in the mold this past Thursday night. Thanks again Bill and Geogie. The installation did not go as smoothly as planned but with a few more pieces of leech-line and wedges they finally agreed to go in. We bonded the panels at the chines with high density filler and epoxy. The clamping will remain in place until the inside of the hull is glassed from the centerline up to the chine overlap. The 90 degree patterns are made for the 44 piece required in that directioin and I'll start cutting them after this post. The current plan is to laminate the inside skin (centerline to chine ) next weekend with a crew of friends and then bring the two halfs togeather the week after that with the help of the designer.
Kevin

The interior laminate was layed up this weekend (both port and starboard) chine to centerline. The plan is to bond both halves togeather when Jim gets here on Thursday. Once the boat is in one piece we will install the bulkheads that are made and sort out the plan of attack for the remaining interior structure.

A lot has happen this past week. Jim Donovan arrived Thursday afternoon and we went pretty much non-stop until he left to return to Hawaii last night. So here is what we've done in this last push.
The hull halves have been brought togeather and bonded. A bow transom mold has been made and the part made from it has been laminated and installed. Bulkheads A, B, C, aft water-tight and stern transom have been bonded in. The centerline web between A and B has been installed and a horizontal plate now refered to as the Cat Bunk is bonded in place forward of the A bulkhead and the bow transom. The plug for the keel recieving box has been started. I'll post some photos soon. Kevin |

So I get a phone message from Kevin last night - he's finished laminating the keel box inside the hull.
Kevin seemed a little "tired" and possibly even grumpy. I quess an hour of hunching over some stinking bit of laminate in the bottom of the hull, and then trying to get a leaky bag fixed can do this to you. Of course I was the guy who got the glorious task of cramming myself in foward of bulkhead "A" to do the forward lower bond. That was HUGE fun. Kevin will be happy that he's finished that bit of boat. The rest of the keel structural parts are designed to be built outside the hull. |

Yes I might have been a bit grumpy and you bet I'm glad that piece is done. The keel head is under the heat lamp post curing as I type. I thought I'd share some more photos of the project taken over the passed couple of weeks.
Jim Donovan: thinking about getting glued permanently into the bow. Kevin: fitting the transom. The fu*&%%$$ keel box.
