You guys are talking about theoretical hullspeed, which is more like a rule of thumb than a law of physics. Boats with displacement hulls can and do exceed their theoretical hullspeed all the time, including by heeling (which lengthens your LWL), or by surfing along the front of a wave (which turns your displacement hull into a planing hull, albeit briefly). For an M23, 6.5 kts heeled and 8 kts surfing are both very plausible. ----- Original Message ----- From: "Dave Scobie" <scoobscobie@gmail.com> To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Sent: Tuesday, July 19, 2016 6:51:22 PM Subject: Re: M_Boats: 1) BBQ 2) m23 speed M23 waterline about 21'10". hull speed is about 6.3 kts. otherwise i'm in agreement with what Connie wrote. -- :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: M17 #375 SWEET PEA - www.m17-375.webs.com On Tue, Jul 19, 2016 at 4:45 PM, Conbert Benneck <chbenneck@gmail.com> wrote:

Hi Josh,
Maximum hull speed is a function of waterline length. The longer the waterline the faster the ship can sail.
Our old 29-footer would sail at 5.5 to 6.0 knots with about 12 knots of wind, on the ocean.
If the wind increased I might see the occasional 6.5 knots.
Therefore I hardly think that an M23 can reach 8 knots, unless the situation is exceptional: with spinnaker; going downwind; optimum wind strength; relatively flat seas....

Just curious what the preferred grill mount is for the m23 if you have the
little round magma one. I see Dauntless had it drop out and down just a hair off the stern on starboard side. (Can see on you tube under dauntless)
Can an m23 do 8 knots ... In shore costal on lake Minnetonka.... I just restored one but have never sailer her! I think according to Bones it will do about 6.5. Any other m23 owners have any thought to add here?
Ps how many m23 owners are in Minnesota ... Are there more than two.?.?
Fair and fresh winds to all of you.
