Re: GT27 Build (Wes K)

Rain on the weekends has slowed progress because I need dry conditions to lay out and cut the panels in my driveway. Here's the progress so far. Still need to trim the edges back to the midpoint of the nearest stringers/cleats.

Re: GT27 Build (Wes K)

Happy new year everyone! I ended up gluing on the cleats to the hullsides. I found that by slimming them down to 3/4" thickness (though still 1" high), it was much easier to get them to take the very modest curvature of the hull. This still leaves a decent amount of gluing area and plenty of support...

Re: Preparing for GT27 build - questions

Thanks for those details. Only the forward and aft cockpits are closed up at this point. For those, the edges against the hull received the same fillet plus two layers of the 6" wide biaxial tape (12 oz. tape) as used elsewhere for the stringers and floor frames. I can add more layers that's advisab...

Re: Preparing for GT27 build - questions

My biggest concern about adding cleats is that, to bond them to the curved hull at this point, I'd need to somehow brace them with enough pressure to get the 1x1 cleat to take the curvature of the hull until the epoxy cures. If anything slips out of alignment, I risk not having a truly level "landin...

Re: Preparing for GT27 build - questions

Jacques, Looking over the GT27 plans, I just noticed that one of the drawings shows a 1x1 cleat attached to the hullsides to support the outboard edges of the flooring. I had not noticed this before, and a different (overhead) diagram of the floor frames shows no such cleat against the hull. I'm won...

Re: GT27 Build (Wes K)

Progress has been a little slow with holiday shopping, decorations, family visits, etc., but I got the floor of the front cockpit and the fuel tank coffin box fiberglassed w/ 9oz cloth just to provide extra protection in case any moisture ever sits on those surfaces for awhile. Aft cockpit floor is ...

Re: GT27 Build (Wes K)

Hey fallguy, I forgot to comment on it earlier, but your build looks fantastic. I stop over on your build thread often to watch the progress. You do great work!

Re: GT27 Build (Wes K)

Thanks for that link OrangeQuest! swglenn, you've got it backwards... propane is heavier than air (perhaps you're thinking of natural gas?), flows downward like water, and requires an overboard drain hole from a safe locker to ensure the gases don't collect in the bilge. Here's one of the clearer wr...

Re: GT27 Build (Wes K)

Thanks guys. Topwater, are your scuppers open or covered by a flap? Any downside to having them that large? My concern about going too large on the GT27 is it's so unlikely to take on water, but large scuppers might actually let in following waves and keep the floor wet. Having no experience with sc...

Re: GT27 Build (Wes K)

So I'm finding that a common recommendation (per ABYC) is that scuppers should be able to evacuate 75% of the water in a full cockpit within 90 seconds. I'm planning to install closed seats in the aft cockpit so that I have sealed storage area for propane tanks on one side and a water pump/filter on...
