M23 Dhana on Lake Chelan
by Gerald Wyatt 14 Jul '17

14 Jul '17

Hi All, I posted some neat pictures from a four day trip on Lake Chelan on the MSOG Photo Site. If you live in the Pacific Northwest and like isolated quiet locations, you might want to explore Chelan on your Montgomery..... Let me know if you would like information on the lake. A Montgomery 23 is perfect for extended cruising on this lake. https://msogphotosite.com/Scripts/StoryTechnical/storytechnicaldetail.php?i… Gerry

Zincs needed for my M17??
by Tyler Heerwagen 14 Jul '17

I have the boat in the water for the summer. Wondering about corrosion to rudder fitting, anything associated with the Keel or centerboard, and anything else that does not occur to me. It's in salt water, I do keep the OB tilted out of the water.What do you recommend? Any specific products or methods?Thanks,Tyler H.SeranitaM17 #232

Ah, the blessing of being on the dry side of the hill! On Jul 12, 2017 11:16, "Gerald Wyatt" <wyattgs(a)gmail.com> wrote: Hi Mark, Not bad at all. I didn't use mosquito nets or bug spray and only came away with a few bites. It is likely the bites came during hikes. With Chelan being on the east side of the cascades there is less rain then on the west side and much less bugs.

Very nice. I'll have to put it on my list of possible cruising destinations. How were the mosquitoes and noseeums?

Well, since you asked Jerry, I've been mooring the boat by this ring. It's a small lake ( very small, only 200 odd acres) and I haven't been using the clear because without chocks I worried about chafe on the mooring line from toe rail or the bow fitting. Perhaps that is part of the problem? I rebedded this in 2015 and likely did a poor job and allowed water intrusion. The off centered force from mooring the boat here might have exacerbated this. Still, I am surprised it was an issue since the bow ring shouldn't be seeing that much water ; it is pretty high up.

on my 17 circa 1977 there was a wooden block glasses into the hull. I added a layer of glasses and refilled the 2 holes and used ss nylon locknuts on the 2 legs of the boweye.
