 Interior Cabin sole gelcoat (Floor ) cleaning. Still thinking about to keep original gelcoat on cabin sole and built in cabin "furniture".  During 40 years and and my and not only my repair activity  "white" floor was used actively and had was weathered pretty much. Fortunately gelcoat  layer is pretty descent, so I decided to sand it to clean polish and wax it. Easy to say, but it is a lot of work. about 10 hours work on the floor with 3 types of sanders and manual sand blocks.  sanding order 120 grit, 240, 320, 400, 600. After 600 plastic still have satin look, but it is really smooth.  There several places where gelcoat was too thin and I sanded th the glass. Yes, it is some imperfection , but I would rather left them as is. I processed all "white" parts on the floor in the cabin. Wood covered areas (as you remember we removed all rotted plywood) does not require so clean sanding and cleaning, just 80 grit sand to remove old glue and make surface prepa...

Interior Cleaned floor from sealant adhesive leftovers, sanding gelcoat to make fresh surface and remove "ups" epoxy  drops. First run around is complete.   Grind openings in the floor was done to investigate area around compression post, prepared area fro re-glassing. Sailing Afternoon  we get out for sailing. nice day 10-20 knots wind. Upwind  sailing Speed is 6.1 knots (11 km/hour) Wind 17 knots boat heel 23.8 degrees, yes we are overpowered.

 Little work this week, actually nothing to picture Sand excessive glass on the knee connecting deck and port side bulkhead holding steering block Checking color and properties of PVC flooring i plan to use on the cabin sole Reviewing the base under the mast and planing course of actions there  Made new insert covering manual bilge pump and installed it Put breakers locks (to protect supposed always on and  always off breakers to be mistakenly operated) Get out and readjusted autopilot parameters.  Removed Cockpit compass and cup holder board from pedestal to make new one or repair and adjust existing one. VicVic  made template for bow block to insert under bow roller to put back screws.  Manual water pump, connected it to water system, but looks like check valve is too tight for this solution, water flow from manual pump is going to be small, but maybe it is not a bad thing ;) Checked mast alignment.  Mast appeared tilted to port side for 3/4 inch if ...

Interior Removing old Teak and holly plywood from the floor. It was mostly de-laminated and rotted in about 50% of surface. Galley floor in process Younger son provided great help today Whole floor cleaned up from wood. Windlass. Windlass battery strapped down. Pulled out chain and marked 40, 60 and 80 feet points with pieces of webbing to make length tabs Engine room.  Glassing "the shelf" over the opening originally left by builders. This area was just a hole opened directly from engine room to cabin. Result engine room wall was just "in air" and any water splashed in this area will be ended pilot berth really wet.. Another thing which had to be addressed - the bulkhead to deck connection. it was very weak and bulkhead traveled about an inch side to side when any load applied to steering. I am not sure the stiffening this joint this way is right thing to do, but i hope it will provide some support to bulkhead. it si to side direction.excessive glass should be cut...

I planned a long, productive day, but it appeared a very short, However some things was done. Interior Cabin sole Cabin sole floor demolishing started. leftovers of water damaged plywood removed from the front cabin. My younger son helped a lot. Main cabin and galley left to do. We found the original Teak&holy floor was just decorative, it was 1/4" thick or even thinner. <<picture will update later>> I am looking for options to make PVC flooring, likely I will do it with rigid locking planks, like laminate floor, but PVC Cabin table  Checked how it fits the slipping place  to be set as sleeping platform.   It is nice, is not? However when I made it I  did "little improvement", I mare corners radius the same and make exact 90 degrees corner. Now I know  I had to make it EXACT as original one. I appeared it does not fit to place as it should to be a part of sleeping platform. It has a 1/2" gap and holding ribs are about 3/4, so, it will not sit tig...

Engine instruments I have designed Engine monitoring module. It is based on Opensource SensESP project . More details  about open source project here: https://signalk.org/SensESP/pages/getting_started/ https://github.com/SignalK/SensESP   I have bought relatively cheap 4000 RPM tachometer with M16 sensor on AliExpress, for  my 2MQ20 engine, however it appeared, that sensor signal is not strong enough enough to get it work stably on RPM >1200.  https://www.aliexpress.us/item/3256807066465803.html At any case I planned to make engine monitor module and connect sensor to it, and then to tachometer. What I had to do - add signal amplifier/filter circuit to monitor module to feed physical instrument with strong enough signal. My engine monitor board design:    What features implemented on the board? Sensor - Starter battery Voltage Sensor - Alternator output Voltage  Sensor - Throttle position (potentiometer input) Sensor - Fuel Tank "1" level (ADC input...
