I30 Mark II Profile Drawing

Hello fellow Islander owners!
Does anyone have a profile drawing of the Islander 30 Mark II? An interior layout drawing would also be very helpful. I have the I30 drawing and I'm trying to determine the differences between the I30 and the I30 Mark II.

Bert,

Sorry, I don't have reference drawings of the I30-2, nor have I found any on the Internet.

However, I can tell you there's quite a difference between the I30 and the I30-2. You can read about some of the differences in this post.

Regards,

Tom

Re: I30 Mark II Profile Drawing

Interesting information, and not a whole lot of other people are jumping on this bandwagon just yet. It will take a bit of convincing that the I30 and the I30 Mark II don't share the same hull and simply have updated interiors and perhaps a different rig. Again, I haven't seen a Mark II to be able to compare. I find it strange that I've seen lots of B30s and a lot more I30s, both quite distinctive from each other, and yet no I30 Mark IIs. Those Islander owners who claim their boats are Mark IIs (no documentation) have, in my opinion, an I30 hull, not the Bob Finch designed B30 hull. Of course, I'm not going to lose much sleep over this, I just don't believe everything on the Islander web sites.

Re: I30 Mark II Profile Drawing

Scanned from an old (1975) book I've got, but no interior plan.. don't know if this will help much... FWIW I think this is the I30 MKII, quite different from the original, as you say, and that the B30 is an upgrade of this original 1970 design...

Re: I30 Mark II Profile Drawing

Interesting! Sure looks like a Bahama. It's too bad the underbody isn't outlined, that would be the definitive view. Thanks for the info, I will add it to my collection.

Re: I30 Mark II Profile Drawing

Yes, I have interior and exterior. I just took pictures of both, and think they are attached to this. Note, the interior one shows the Dinette arrangement, however, some, mine included, did not have this, it has a fold down table on the bulkhead and couch/settee on both sides.

Re: I30 Mark II Profile Drawing

John

Thanks so much for these drawings! With the sail actually showing the Mark II designation I have to take these as gospel at the time. Too bad there is no year listed. Interestingly, the underbody is identical to the Islander 30 and not the Bahama 30. I have my suspicions that the Mark II is simply a development of the original Islander 30 designed by McGlasson, not by Bob Finch. Research continues.....

Re: I30 Mark II Profile Drawing

Now I'm confused:

This is the McGlasson I-30:



Even though there's no underbody profile it's difficult to believe the underbody here is going to be anything like the MKII images posted by John - in fact I'd strongly suspect its a full keel/attached rudder..



Clearly the MKII above, and the Bahama 30 below:



It seems logical that the McGlasson 30 (top) is the 'original', the 1970 Finch the 'MKII', and the B-30 a refinement of the Finch boat as they are very similar to each other in many ways (similar hull/deck, but new foils)....

Re: I30 Mark II Profile Drawing

Your confusion has clarified the issue for me!! I did not realize that the "McGlasson" I30 was the original, older design, I've never seen one of them. So although Finch designed both the I 30 Mark II and the Bahama, they are quite different boats both on deck and below, as well as underbody. Thank you for the information! I knew someone would have it sooner or later!
