Motor Sailers?

[TeddyDiver]

Thanks Lazey.. Nice job! I think there's more demand to monos like this in the northern lats.

[Guillermo]

Nice boat, nice numbers, nicely built boat. Congs!

Lot of boat for the money, ask 260k, but want out, , repowered with a 120 4cyl JD would be great world cruiser

This looks like an attempt to create a planing surface for when the boat is under power.

I can see how it might just work without spoiling the displacement speed too much.

Guillermo, The Nordhavn MS 56 is one of my favorites I'm sure it'll get you anywhere, but I'll likely never afford it by retirement time. The Island Packet SP Cruiser 41 footer is a more likely candidate but wants for a controllable pitch prop. The price may be doable. I think you rated it an : H-15/29 on your Motorsailers and Motorsailing website (nice site, by the way). Very usable envelope I'd think but I wonder if it'd be better suited to a slow turning, fuel sipping engine and a larger prop. The available Genoa and captive reel system are requisite. I like the shoal draft and the forward cockpit would be nice with the remote control for the autopilot. OK, I'm getting really lazy now. Go ahead - put the cushions on the cockpit seats.

Hi Knight,
Sorry for the late answer.
The IP SP 41 has lots of power (110 HP), too much for my taste. From the propulsion point of view 50% of that would be enough for a 23000 lbs boat and I don't think appliances can justify the other 50%. The Banjer 37 (27800 lbs) has two basic motorizations, 62 and 95 HP (continuous). I've tested both and in my opinion the 62 HP engine is more than enough. But it seems to be a tendency nowadays to overpower motorsailers.

On the other hand, the ballast to displacement ratio is quite low for a proper oceangoing yacht (STIX 39).

Those two things plus the D/L ratio of 223 and the flat stern sections indicate she has rather been conceived as a good weather 'fast' motoring 'island hopper' in semidisplacement mode.

Cheers.

[White Knight]

Thanks for the input Guillermo. I too thought it was highly overpowered and that's one reason for the need for the controllable pitch prop. It seems I'd usually be running the engine at fast idle speed and wouldn't want to run it long-term underloaded. Then again us Americans never heard of too much power. It could come in handy to vacate an area at the approach of a storm. Still, I think a lazy sailor like me might appreciate the newfangled line handling rig and keep the wife warm and happy to boot. She'll camp out on the water for awhile but not for long. I'm planning to lure her off the shore full time.

[White Knight]

Then again I might ought to reconsider that stability index. HUMMMM - 39. Might she prove to be just a bit tipsy?

[Guillermo]

The STIX tells nothing about the seakindliness or performance of a boat, being just an indication of the boat ability to cope with strong conditions from the point of view of stability.

An STIX number close to or over the boat length in feet is a desirable characteristic, so 39 for a 41 footer doesn't look too bad.

Cheers.

[White Knight]

Yeah, thanks - I follow you. STIX is the ability right oneself from an upset. I knew that. It's also a rock band and a river in Hell, according to Dante. Appropriate - Huh? Or is that Styx? I was unsure of the optimum index rating. Close to length is good rule of thumb. More is better, OK; but is Stix figured with full sail, motoring under bare poles; no poles either, or what?

[Guillermo]

Shall I refer you to the STIX thread? You'll find there all you wanted to know about STIX and didn't dare to ask about....

Cheers.

[TeddyDiver]

You must feel the STIX and come to the dark side

[White Knight]

Maybe I don't know as much about STIX as I thought. Go ahead STIX me!

Any comments on GLEN-L design motorsailor "KODIAK 29"?Any body with some experiance with building/sailing with this boat?

Best Regards
Todor

I seek to contact me trevor bolt
I am interested in the 34 foot to build.
but I can not communicated with the architect trevor bolt
I already send mails but several unanswered.
Can you help me?
thank you
