I've got my Moses 679/710/483 set with 82cm mast today. Pretty exciting as I recall Jimmy was talking about 80cm mast this time last year and finally it became available.
So here it comes, component by component
2020 82cm mast
It's an awesome length to ride shallow waters and for folks like me who feel that 71cm is too short but 91cm is catching bottom in OBX/SPI - this one I wanted for a while. As reported previously it's designed sturdier and I realized quickly why so - the tapering on the mast is not gradual but instead the mast thickness changes very little throughout mast length and it gets thinner only last 4" on the bottom (pic below). Even being thicker in the middle it still weigh almost proportionally (71cm 2.7 lbs, 82cm 3.16 lbs, 91cm 3.4 lbs).
Once I saw a pair of extra mount holes I got excited thinking that it would help all the folks who have 140mm mount hole spacing on their boards (for aluminum masts) and then I measured that spacing on 82cm mast is 137mm, which is out of world of mechanical engineering I studied. I guess a bright side of that is that you can move the mast more forward, and ride 590 with 2020 Micro comfortably. Beats me, I have no clue why another nonstandard thing needed to be introduced.
But overall - very good mast and I like it.
came home and ran comparison of mast position (fuselage tip against the wall) and found out that 82cm mast positions fuselage 30mm forward compared to 91cm. The 105cm mast positions fuselage 10mm back of 91cm mast. The 91cm and 105cm mast are slightly angled back, while 82cm is just straight perpendicular to the mast plate.
2020 679 wing
as everyone knows the numbers on Moses wings/stabilizers indicate wingspan in millimeters. Wingspan of 679 wing is 686mm. I know. I measured several times on both sides with same tape I used yesterday to measure 695 wing to match specs. Well, at least confusion of 683s vs 683 is past us. The wing is pretty and I wish I had my 683s to compare it to but it's in Cape Town now being demoed by a friend. Certainly the wing is slightly lighter than 683s because my 683s/710/450 weigh 4.2lbs and 679/710/450 3.9 lbs (710/450 is same weight in both cases). As it came 679/710/483 is 3.8 lbs, finally lighter than 633/749/483 which was 4.0 lbs in its latest/lightest version
683s has been my "wing of 2019" and I sold the 633 promptly after getting 683s. 679 will certainly serve well and it will get its use in OBX where seaweeds would mess with riding a wing like 695. I hope to pair it with thinner 425 stabilizer and get a stunning combination. Will report on that once I have feedback.
I didn't notice any changes on 483 stabilizer and 710 fuselage. Clean and pretty.
A lithium grease tube supplied with set is itty bitty now and there are no M6 t-nuts supplied. The wooden plates holding mast in place were attached by wood screws and zinc plated hex head bolts. Which means no extra T30 M6 bolts either (and it's not a problem).
See some pics below and get yours to get ready to rock for the season to come
