Don't put any more varnish over soft stuff. You may wind up with a real mess to clean up. Switch to Two part paint if you are having issues with the varnish.

Thanks for info.Googled varnishing on wood boats and read instructions.said to thin first coat so varnish penetrates deeper.read can I used and it said not to thin so might have to scrape off finish on porthole window frames and try something else (or build new)Tried sanding this morning and frames seams to be dry.read spar varnish is a little softer to allow for wood movement;maybe that's it.will try thinned varnish to seal up new wood and unthinned for more coats.had a few problems with epoxy runs on cabin sides so will have to sand those down first then varnish.

:D Called in order to Glen-l today-more epoxy and fillers and Epifanes varnish.Should be here in week or so.will come UPS ground.Hope 2-1000 ml cans of Epifanes will be enough.got the epoxy and fillers to make fillets on inside of motorwell and corners on rear sole.and for glue for flooring.Sure was nice to talk with Gayle this morning.Good to hear about her dad and am anticipating the order.Picked up a little more cedar and a sheet of exterior ply for core of rear door and to build fold down pantry door that doubles as eating table(bar)

:D I'm kinda in a quandry about boat power;I was currently going to use the older Evenrude low-profile 15hp to power my craft.However was offered a Mercury 2-stroke 25.the 25 weighs more but has more power(if I put power prop on)but will drink more fuel.They both are the same shaft length (20") have electric start.The 15 has a bolt through the tilt tube.unknown if that holds motor together or what.the 25's is open.I used to use the 15 to power my old 24' steel pontoon boat so was ample power.Anyone want to weigh in ?

I can't imagine the weight being an issue in that size of a boat. BoJest specs say 5-10 horsepower right? If I'm correct in a displacement hull more power will really not net you much increase in speed, just increased fuel usage.

:D I understand .The plans recommend 5-10 hp.That's for an inboard shaft drive engine.was wondering if the hp of outboards was similar or what?I've noticed from the other Bo-Jest builder that some have used 30hp.figure I probably won't go any faster with bigger motor,however a little extra might come in handy if needed(rough seas or excessive current on rivers)I also decided on one fuel tank instead of two small ones.I can put fuel on one side of boat and water storage and holding tank on other.

The extra hp will not get more speed. That is forward speed plus or minus current. Hull speed is your speed related to the water. It will help going into a strong wind.

I had an 8000# 27' sailboat with keel. It had 7.5 hp diesel. It would go hull speed. It did let me down one time. I was trying to pull another sailboat into a strong wind. It didn't help that my prop. was covered with barnacles.

Modern outboard hp is measured at the prop shaft. Inboards is just the HP rating at the flywheel or whatever. Not sure how much you lose in a marine trans.

:D Was hoping the motor would last this year.plan on a better 4-stroke next year.unknown if I'll even get it in the lake this year.Got my 2 boxes of stuff from Glen-L today.Looking forward to this weekend so I can do more fibreglassing.need to work on inside of motorwell as well as the side decks.most of the side decks will be totally covered up by top board.there will be drains along bulwarks for rain water as well as ventilation shafts for the bilge.gotta figure out side vents that are not made of plastic.back door was made wrong so have to redo frame.lots of little things to do. :D

Tim, nice pattern on the table!

I have 4 of those exact same chairs. They're fine for normal use, however, be careful as the glue joints at the base of the back failed on most of mine and I had to re-glue them. One of them now serves me as a stool in my garage.

Chair won't stay in boat-will probably use something that folds up for storage.Having problems with sliding door on back of pilothouse-might have to use hinges on door.No room to open out -will have to open in.cuts down on interior room ,however could use open door as bathroom door in pinch.got my fuel tank and will be mounting in that soon.also playing around with steering system.
