Re: S2 7.9

ajoliver- Hey, I try! I prefer to ask intelligent questions, not ones I can have answered with a quick Google search anyway. Believe me, I know all about cavitating, that little 3 hp on our Renkin did it like crazy every time we went over a wave! Thanks for your thoughts, I really appreciate it. I must say that my ideal 7.9 would have the inboard Yanmar diesel, but I've heard enough about the BMW diesel at this point that I'm considering it more of a detriment than an advantage!

Re: S2 7.9

Question for those that have/had a 7.9 or know about them. On an inboard converted to outboard, does it matter which side of the rudder the outboard is mounted (port or starboard)? Also, am I correct to assume that the "original" outboards have better resale value than the ones converted from inboard?

Thanks!

If I may...

My Morgan 22 has a Nissan 5hp. As has already been mentioned- in the bay on flat water and no headwind it is fine. However, it will not get my boat to hull speed. I go much faster under sail than I do on the outboard. Heading into wind and waves, there are times when I'm not going much of anywhere. When I am returning from offshore to my marina, there is a channel I have to travel and then a drawbridge I have to wait for. The sails have to come down when I get to the channel, so there is a fair bit of motoring. At the end of the day I am part of a parade of boats heading for home. Since I can't run hull speed, I have to get out of the way a lot because I'm holding up traffic putting along. Other sailboats are cruising 5 knots on the motor and I'm doing 2-1/2 if there's a headwind.

I don't know about anyone else, but I swear on all that is Holy that wherever I need to go there is a headwind.

The carpeted headliner is a minus. They tend to get moldy and are a pain to remove. The glue used seems to bond rather well to the fiberglass. Another area to look out for is the rudder attachment. Most have been reinforced and/or retrofitted with stainless plates. They also have an inboard model. The BMW diesel tends to be problematical with age and expensive to maintain. Some of these inboards have been retrofitted with 1 cyl Yanmars which is a more reasonable solution. The inboard is preferable in bigger waves and chop as it does not come out of the water like an outboard prop.

It is not exactly a ling distance cruiser but it is a fun boat to sail. You can trailer it to where you want to go and happily live/sail on it for a week with little problem. I wouldn't be afraid to be out in a blow with one but for the big stuff you need some heft which translates into a boat that would not be trailerable. Some owners have told me that the boats with hull number 400 or higher are the ones to look at.
hold on there mate, laughing sally, a 7.9 from cedar island yacht club was racing on the detroit river with board up and spinnaker up in maybe 15-20 knots. boat capsized, went under and was never seen again. all the crew was fine. not much of a blast there.

Re: S2 7.9

Racers often push their boats to the limit, and with small boats under spinnaker, the limits can include sinking them. For example, a fairly common occurrence with racing J24s.

I do think the fact that risky sailing can sink the boat does not conflict with the well-stated advice regarding their desirability and usefulness for the OP. Remember he wants a trailerable boat, and pretty much anything trailerable, probably is sinkable. The 6.9 offers the OP the best of that class, but it is still a member of the class, unless you chase one of the keel versions, which becomes not trailerable.

Sailing like life is full of tradeoffs.

Certified...in several regards...

They found the rudder, belonged to a friend of mine. Key words are they had the board up and the hatch open.
Another friend did the same thing with a Paceship 23. You can sink them if you try hard enough.

Re: S2 7.9

I'm not particularly concerned about that, as has been said: any boat can sink! We'll be sure to have the hatch boards in if we are running under spinnaker, have the board up, or are in rough seas. Anyone have any insight into my last question concerning the mounting location for an outboard?

Re: S2 7.9

I think that basically all outboards are mounted on the Port side of the transom, maybe because most Sailors are right handed ?

I would stay with convention,

Re: S2 7.9

Yeah, that's kind of the impression I've got too, most of the pictures of 7.9s (and other sailboats with outboards) have it on the port side, but the one I'm contemplating currently has it mounted on the starboard side. Do you (or anyone..) think that this is something I should be concerned about? Perhaps there is more weight on the starboard side due to the head and battery being on that side, and so the engine should ideally be on the port side to counterbalance it? Am I overthinking this?

Thanks!

Re: S2 7.9

Oh, and should I be concerned about spiderweb cracking like this in the deck?
